INTRODUCTION
Description of the Shediac Bay Watershed Association
The Shediac Bay Watershed Association (SBWA) was founded in 1999 as a result of
growing concerns from local community residents over the ecological health of Shediac Bay. In
order to establish a long-term water quality-monitoring program, a community-based association
was formed.
The Shediac Bay Watershed Association vision and mission statements are as follows:
Our Vision – Communities working together to foster a healthy ecosystem that will sustain the
quality of water for future generations.
Our Mission – The SBWA will accomplish its vision through education and community
stewardship.
The Board of Directors includes the following members: Mr. David Dunn, President Mr. Gerry Dionne Mr. Denis Haché
Mr. Armand Robichaud, Vice-President Ms. Connie Doyle, Treasurer Ms. Brenda Ryan
Mr. Victorin Mallet, Past President Ms. Frances Kelly, Secretary
Mr. Bill Murray, Past President Mr. Joe Caissie
Ms. Dominique Audet Mr. Erick Bataller
Mr. Pierre Landry Mr. Léo-Paul Bourgeois
The Shediac Bay Watershed Association gratefully receives guidance, donations and in-
kind support from various organizations and interest groups. SBWA has a database of over 325
stakeholders consisting of business-owners, industry, foresters, farmers, local residents, cottage
owners, recreation boaters and swimmers, conservation groups and community organizations
within the Shediac Bay Watershed.
Overview of the Shediac Bay Watershed
The Shediac Bay Watershed covers 400 km2 of land area and stretches along 36 km of
coastline, from Cap Bimet to Cap de Cocagne (Fig. 1). The Shediac Bay Watershed is composed
of two major river systems emptying into Shediac Bay: the Shediac River and the Scoudouc
River. The Shediac and the Scoudouc rivers are characterized by dendritic patterns of small
tributaries covering a watershed of 201.8 and 143.3 km2, respectively. The Shediac River is
composed of two major water arms. The northern water arm is created by the convergence of the
McQuade Brook, the Weisner and the Calhoun Brook. The southern large water arm of the
Shediac River is the continuation of the Batemans Brook. Water velocity in both rivers is
generally weak due to the gentle regional elevation. The watershed boundaries stretch into both
Kent and Westmorland County and cross into both the Shediac and Moncton Parish. During
summer, the Watershed region consists of a population of approximately 15,000 people.

SHEDIAC AND SCOUDOUC RIVERS WATER QUALITY
MONITORING
Introduction
Water quality monitoring began in the Shediac Bay Watershed during the water
classification program in 2000-01. Basic physical measurements were then taken at the same
sites from 2002 to 2006. In 2007, additional parameters were measured (nitrate-nitrogen, total
phosphorus and E. coli counts) on a monthly basis at each sampling sites. The water quality
monitoring is used to support the need for specific remediation actions and measure the
effectiveness of the work. It is also used to complete detailed sanitary surveys and establish the
status of our rivers.
Such monitoring helps determine if changes to the water quality occurred and if sections of
the stream or river remain are suitable for aquatic life. It is of outmost importance to have
accurate and continuous data of water parameters for the watershed. This allows for effective
management strategies and the creation of remediation plans.

Material and Methods
2.2.1 Water Quality
Water quality testing was conducted between June and October 2014. Sampling sessions
were conducted on a monthly basis at 9 sampling sites (former Water Classification sites) (Fig.
1).
Water quality sampling was performed using the protocol developed by the New
Brunswick Department of Environment.
Basic water quality parameters (DO, temperature, pH, conductivity and salinity) were
measured using a water-condition instrument YSI QS600. Total coliforms, E.coli, Nitrate
concentrations and Phosphorus were measured in the lab of the Petitcodiac Watershed Alliance.
The equipment needed to perform the stream habitat assessment included clipboard and
pencils, waders, GPS unit, digital camera, water-condition instrument (YSI), reference
documents (identification key), meter stick and measuring tape as well as waterproof board and
field sheets.
2.2.2 Macro-invertebrate
A Benthic Macro-Invertebrate survey was performed on a test site in the Weisner Brook,
tributary of the Shediac River on October 30th 2014. The protocol used was based on the
Canadian Aquatic Biomonitoring Network (CABIN) in partnership with a study from the
Southern Gulf of St-Lawrence Coalition (SGSL).
Sampling was done using a 400µm D-frame net (kick-net). Benthos was disturbed during a 3
minute period with the net facing upstream to allow collection of disturbed benthos and
invertebrates in the kick-net. All specimens were stored and preserved using 70 % ethanol.
Macro-invertebrates were sent to the University of Moncton, Moncton campus, at the Atlantic
Region Environmental Science Centre (ESC) laboratory. The site data from field sheets
including site photos have been entered in the CABIN Data Management website.

Results
2.3.1 Shediac and Scoudouc Rivers Physico-chemical Characteristics
2.3.1.1 Water Temperature
Water temperature can fluctuate depending on the period of the day and during season
changes. Values are influenced by numerous factors such as shade covering the stream, water
velocity and water depth. It is considered that water above 25 or 29 degrees Celsius (ºC) tends to
be of poor quality because less oxygen can be dissolved. Therefore, water temperature directly
influences the dissolved oxygen levels.
The overall mean water temperature for all sites was 15.05 ºC, which is an acceptable
value. The overall mean water temperatures were 14.52 ºC and 15.46 ºC for the Scoudouc River
(Fig. 8) and for the Shediac River (Fig. 9), respectively. The highest temperature recorded was
25.3 ºC, at site ShdE on July 23rd, and the lowest temperature recorded was 7.26ºC, at site ScdB
on October 29th. The overall mean water temperature for both rivers during the 2014 sampling
season was 14.9 ºC.

2.3.1.2 Dissolved Oxygen
Dissolved oxygen (DO) represents the concentration of oxygen in gaseous form in the
water column. Most of the oxygen in the water comes from the surface atmosphere and is mixed
in the water by turbulence and current. The measurement of the concentration of dissolved
oxygen in surface waters is essential for measuring changes in water condition and rating water
quality. It has a direct effect on aquatic life and can be influenced by stream habitat alteration.
DO is essential for fish and many other forms of aquatic life. DO vary with temperature, tending
to be higher when the water temperature is low. According to the Canadian Council of Ministers

of the Environment’s (CCME) Canadian water quality guidelines, the minimal amount of DO
required for cold water aquatic life is 9.5 mg/l (early life stages) and 6.5 mg/l (other life stages).
In 2014, the overall DO mean for all the sites was 10.88 mg/l. The overall mean for the
Scoudouc River (Fig. 10) and the Shediac River (Fig. 11) were 8.99 mg/l and 12.14 mg/l,
respectively. The highest level recorded was 20.32 mg/l at site Shd C on June 25th and the lowest
level recorded was 2.89 mg/l at site ScdD on June 25th. The highest and lowest levels seem out
of the usual range, there is the possibility that those readings are incorrect. As in July, we could
not get a reading for the sites ScdB and ScdE. The months of September and October, the YSI
was also not giving any readings for DO, we will fix the issue for the next field season. The
overall DO mean for both rivers during season 2014 was 10.56 mg/l.
FIGURE 4. DO LEVELS FOR THE SCOUDOUC RIVER, 2014 FIGURE 5. DO LEVELS FOR THE SHEDIAC RIVER, 2014
2.3.1.3 Potential Hydrogen
The potential hydrogen (pH) level indicates the acidity level of a stream. It affects how
much other substances (such as metals) dissolve in the water. Many organisms that live in water
are sensitive to changes in pH and may be adversely affected by pH that is either too high or low.
The pH varies naturally depending on bedrock, climate and vegetation cover, but may also be
affected by industrial or other effluents, the exposure of some kinds of rock (for example during
road construction) or drainage from some mining operations. According to the CCME’s
Canadian water quality guidelines, pH should be between 6.5 and 9. Levels under or above these
may cause some problems for aquatic life in the streams.
The overall pH mean for all the sites was 7.44. The overall pH mean for the Scoudouc
River (Fig. 12) and Shediac River (Fig. 13) were 7.41 and 7.46, respectively. The highest level
recorded was 8.9 at ShdC on July 23rd and the lowest level recorded was 6.31 at ScdE on
October 29th. The pH mean for both rivers was 7.45.

2.3.1.4 Conductivity
Conductivity is the measurement of the ability of water to pass an electrical current. It is
affected by the amount of inorganic dissolved solids (nitrate, chloride, sulfate, sodium, etc.)
found in the water. The conductivity level may be influenced by rainwater, agricultural or urban
runoff and the geology of the area. There are no set criteria for conductivity levels for water
quality, but the US Environmental Protection Agency states that streams conductivity levels
ranging between 0.15 and 0.5 mS/cm usually seem to support a good mixed fisheries.
Consequently, a higher conductivity level may indicate a higher amount of dissolved material in
the water and the presence of contaminants.
The following interpretation for conductivity of 2014 excludes the month of July. The overall
conductivity mean for all sites, was 0.108 mS/cm. The overall conductivity mean for the
Scoudouc River (Fig. 14) and for the Shediac River (Fig. 15) were 0.124 mS/cm and 0.097
mS/cm, respectively. The highest conductivity level recorded was 0.579 mS/cm at site ScdG on
September 24th and the lowest level recorded was 0.016 mS/cm at site ShdE on October 29th. The
overall mean for last year was 0.111 mS/cm.
The month of July was very different from the usual conductivity readings. The levels measured
where between 71.3 and 302.5 mS/cm, with an average of 155.5 mS/cm. This may be due to an
instrument malfunction, but in the event that it is not, we included the results in separate charts.

2.3.1.5 Nitrate-Nitrogen
Nitrogen is essential for plant growth, but the presence of excessive amounts in water
presents a major pollution problem. Nitrogen compounds may enter water as nitrates or be
converted to nitrates from agricultural fertilizers, sewage, industrial and packing house wastes,
drainage from livestock feeding areas, farm manures and legumes. The acceptable amount of
Nitrate-nitrogen for the protection of aquatic life in freshwater is set at 13 mg/l (NO3).
The overall mean for all sites was 0.22 mg/l. The overall mean for the Scoudouc River
(Fig. 16) and the Shediac River (Fig. 17) were 0.29 mg/l and 0.16 mg/l, respectively. The highest
level recorded was 0.98 mg/l at site ScdE on August 28th and the lowest level recorded was 0.01
mg/l at ScdD and ScdE on September 24th. The overall mean for both rivers was 0.23 mg/l.

2.3.1.6 Total Phosphorus
Phosphorus is an important nutrient for aquatic plants, but can be a potential pollutant as
well. Large amount of phosphorus coming from cleaning products (detergents), agricultural and
residential fertilizer components can cause eutrophication. CCME’s guidelines suggest that total
phosphorus levels should be under 0.035 mg/l to maintain a meso-eutrophic state or better.
The overall mean for all sites was 0.10 mg/l. The overall mean for the Scoudouc River
(Fig. 16) and the Shediac River (Fig. 17) were 0.08 mg/l and 0.11 mg/l, respectively. The highest
level recorded was 0.4 mg/l at site ShdE on June 25th and the lowest level recorded was 0.01 mg/l
at multiple sites, on various months. The overall mean for both rivers was 0.10 mg/l.

2.3.1.7 Total Coliform
Coliforms are the commonly-used bacterial indicator of sanitary quality for food and water.
Coliforms are abundant in warm-blooded animals, but can also be found in aquatic
environments, in soil and on vegetation. The acceptable count of coliforms in water for
recreation is set at 400 MPN/100ml.
The overall mean for all sites was 2105.33 MPN/100ml. The overall means for the
Scoudouc River (Fig. 18) and the Shediac River (Fig. 19) were 1994.10 MPN/100ml and
2194.32 MPN/100ml, respectively. The highest “Most Probable Number Count” detectable by
laboratory analysis is >2419.6 MPN/100ml, and it was the level measured at 78% of all sampled
site during the 2014 sampling season. The lowest level recorded (74.4 MPN/100ml) was
measured at site ScdB on August 28th. The overall mean for both rivers was 2094.2 MPN/100ml.

2.3.1.8 Escherichia coli
Escherichia coli (E. coli) is one of many species of bacteria living in the lower intestines of
mammals. The presence of E. coli in water is a common indicator of fecal contamination. The
acceptable count of E.coli in water is set at 400 MPN/100ml.
The overall mean for E.coli for all sites was 199.44 MPN. The overall mean for the
Scoudouc River (Fig. 20) and the Shediac River (Fig. 21) were 267.20 MPN and 145.22 MPN,
respectively. The highest “Most Probable Number Count” detectable by laboratory analysis is
>2419.6 MPN/100ml, and it was the level measured at only one site, ScdG on June 25th. The
lowest level recorded was 25.9 MPN at ScdE on September 24th. The overall mean for both
rivers during season 2014 was 206.21 MPN.

Primary contact: Recreational activity in which the whole body or the face and trunk are
frequently immersed or the face is frequently wetted by spray, and where it is likely that some
water will be swallowed. Inadvertent immersion, through being swept into the water by a wave
or slipping, would also result in whole body contact. Examples include swimming, wading,
waterskiing, rafting/kayaking or subsurface diving (Health Canada, 2010).
Theses primary contact activities are not frequent in Shediac and Scoudouc Rivers but happen
typically during the canoe run in spring.
Secondary contact: Recreational activity in which only the limbs are regularly wetted and in
which greater contact (including swallowing water) is unusual. Examples include sailing,
canoeing or fishing (Health Canada, 2010).
These activities are frequent and regular in Shediac and Scoudouc Rivers.

2.3.1.9 Macro-Invertebrate Survey
Laboratory analysis results of our sample is pending.
2.3.2 Shediac and Scoudouc Rivers General Characteristics
2.3.2.1 Riparian Zones
Overall, the banks were mostly composed of shrubs and mixed forest. Many of our sample
sites are located at bridges and near residential areas for easy access, therefore there is the
possibility of human involvement impacting the water quality. Sources of these pollutants can
include: pollutants from the roadways (fuel, vehicle fluids, etc.), farm lands, cattle fields,
fertilizers, pesticides/herbicides, inadequate buffer zones, etc.
Site ScdG flows through crop fields, and there is a row of shrubs and mixed trees on both
sides. However, using 2015 satellite imagery from Google Earth, the width on these two rows are
approximately 20 metres at its widest and approximately 8 metres at its narrowest. The
remaining 30 metres of the recommended buffer zone consists of grass. There is evidence that
the buffer zone may be inadequate, as the substrate upstream of the sample site is covered by
thick layers of silt for approximately 200 metres. The water levels of this 200m section is very
high compared to downstream of sample site; depth upstream 75cm - >1m, while downstream is
20-45 cm (with substrate of bedrock, rocks and gravel). Upstream and downstream
characteristics of the sample site are completely different in regards to: riparian zone, substrate,
channel width and wetted depth.
2.3.2.2 Substrate
In general, the Shediac River is mostly represented by coarser substrate (rubble, gravel,
rock and bedrock), mostly surrounded by sand with minimal fine particles. Bedrock is only
found in Shediac River, mainly site ShdC is characterized as 80% bedrock with small amount of
rock, gravel and sand. The water is mostly transparent and clear of any colour.
The Scoudouc River is mostly characterized by rubble and gravel and finer sediment (fine
particles and sand). When entering most sites, there is often a cloud of sediment lifted from the
slippery bottom. The water colour is mostly transparent with a yellowish/brownish colour.
18 Water Quality Remediation and Public Outreach Program Final Report March 2015
Discussion
General water quality in both river systems was relatively good. Water temperature and pH
values were acceptable. The Scoudouc River is deeper and the riparian zone is covered by dense
vegetation that provides more shade. Therefore, water temperature is generally lower in the
Scoudouc River.
Water temperatures did not exceed the maximum recommended limits 25°C, with the
exception of ShdE on July 30th, which is very wide at the sample site, therefore has a large
surface not protected by a tree canopy. However, there are 3 other sites in the Shediac River that
had temperatures above 22°C in July, a level that is high enough to cause thermal stress in
Altantic salmon parrs, and that lethal limits range between 25° and 28° C (Crisp 1993). The
limits for growth of the salmon parrs range between 6.0°C and 22.5°C, with the optimal
temperature of 15.9°C (Elliot and Hurley 1997).
Dissolved oxygen values were generally over the recommended guidelines for cold water
species (early and other life stages). However, the values for the Shediac River in June are above
the maximum DO saturation (15 mg/L), which would suggest device malfunction. There are
many other examples of device malfunction: Scd D 2.89 ml/L for June, Scd E 0.10 mg/L in July,
and 0.10 mg/L for all sites in September and October. The dissolved oxygen sensor will be
repaired over the winter to be ready for next season.
All pH levels are acceptable under the CCME guidelines, which are located 6.5 and 9.0 for
the protection of aquatic life. The pH is mostly consistent between the sites during the same
months. We see slightly higher levels (more alkaline) at all sites during July and August.
The conductivity measurements support the fact that sedimentation loading and
agricultural runoff could be a problem at site ScdG, where each value is greater than all other
sites (average Scd G 0.298 mS/cm). In September, the levels are exceptionally high 0.579 mg/L.
As described in the riparian zone characteristics (2.3.2.1), this site is in the center of two farm
fields, and the substrate is covered by thick layers of silt that may be the cause for higher
conductivity levels, due to an excess of inorganic dissolved solids. Also, in July, there was a
dramatic change in the conductivity levels that may be caused by an instrument malfunction or a
unit of conversion error on the YSI reading. The field team took note of the reading of the
machine as it was, therefore it was not a human error. There was no rain 24 hours before the
sampling of July 23rd.
Elevated concentrations of nitrate can be harmful to aquatic life, and may contribute to
excessive growth of algae or aquatic plants (eutrophication). Major sources of excess nitrate
include fertilizer runoff from farm fields or domestic landscaping, runoff from manure and
seepage from septic systems. Levels were within the CCME’s guidelines for water quality and
protection of freshwater aquatic life (13 mg/L) at all sites throughout the season. Levels were
relatively good all season at the site ScdG, which is situated in an agricultural area, and had
lower levels than other sites in the Scoudouc River. All sites in the Scoudouc River had elevated
19 Water Quality Remediation and Public Outreach Program Final Report March 2015
levels in August compared to other months (figure 12). The Shediac River shows relatively low
levels during the sample season (figure 13).
Recommendations in NB regarding water quality for freshwater for phosphorus are 0.03
mg/L. Our results are over the recommended levels in 82% of samples, some by as much as 13
times the recommendation. Looking at data from the previous years of testing phosphorus, they
seem to be consistently higher than the recommended limit as well. There is the question of the
laboratory methodology and precision, however further investigation is needed to establish
proper testing. Other factors capable of elevating phosphorus concentrations need to be evaluated
in the possibility that there is an outside source impacting the watershed.
E. coli is the best indicator of fecal contamination in fresh waters by fecal matter by human
or animal origin. Typical sources in the watershed include wildlife, farm animals and
malfunctioning sewage systems. The presence of E.coli usually has little effect on the health of
aquatic life, but may affect the suitability of the water for recreational use. This is why the results
are compared to recreational use guidelines. Most E.coli is not itself hazardous to humans (with
the exception of some less common strains) but the presence of E.coli indicates an increased risk
that other more harmful pathogens may also be present.
E. coli concentrations are elevated at the site ScdG in June, with a value that exceeds the
maximum detection limit (>2419.6 MPN/100 ml) and is the highest concentration for 2014, and
is also elevated compared to other sites in august and September (figure 18). Farming activities
and waste water treatment lagoon runoffs could influence the E.coli concentration in the
Scoudouc River.
Continuing to perform water quality monitoring is of the utmost importance in making sure
our watershed is properly managed. Such activities complement remediation work by
determining not only where work is needed most, but also if such work is accomplishing its
purpose.
PARTNERSHIP WITH STAKEHOLDERS
Stakeholders and Partnerships
Continued industries and stakeholders partnerships are essential to continue long term
remediation efforts. Future remediation steps include the reduction of siltation in many small
tributaries of the Scoudouc Rivers, where human activities such as ATV crossings are affecting
the habitat integrity. SBWA is in contact with the ATV Country Wheeler Club.

HABITAT AND WATER QUALITY ENHANCEMENT
Community Aquatic Community Program
Again this year, we were able to monitor the water quality within the Shediac Bay Watershed by
partnering with the Department of Fisheries and Oceans on the Community Aquatic Monitoring
Program (CAMP) from June to August of 2014. This is a long-term monitoring program aiming
to study ecosystem evolution and changes over time. Data collection is expected to continue in
the 2015 field season.
FIGURE 20: COMMUNITY AQUATIC MONITORING PROGRAM (CAMP), FISH WITH SPINAL DEFORMITY, (2014).
Freshwater mussels in Shediac and Scoudouc Rivers
Freshwater mussels are an important part of a river’s ecosystem, as natural filter feeders capable
of filtering up to 37.8 liters per day, they help maintain the quality of the water. The SBWA has
been conducting freshwater mussel surveys to assess populations and freshwater mussel habitat.
In recent years, the disappearance of the species “Brook Floater” (Alasmidonta varicosa) in
various parts of North America, has raised concern for the status of the global population of this
species.
In 2005, SBWA found the Brook Floater at several locations in the Shediac and Scoudouc River.
This last summer, the field team has attempted to re-confirm the presence of the Brook Floater,
without success. The team did find a healthy population of a more common species, the Eastern
Pearlshell (Margaritifera margaritifera), with a count of 8,746 individuals.
FIGURE 21: FRESHWATER MUSSEL SURVEYING IN THE SHEDIAC RIVER, 2014
21 Water Quality Remediation and Public Outreach Program Final Report March 2015
Habitat Restoration
Fish Habitat restoration is a major initiative of the SBWA. Areas where bank erosion
occurs causes an excess of sediment in the watercourse, that can cause various issues for aquatic
ecosystems; it can suffocate fish and fish eggs, bury aquatic insects, can carry harmful pollutants
such as phosphorus that can further worsen conditions of the ecosystem, etc.
Fish passage issues are both naturally occurring and man-made, like beaver dams, debris
jams, hanging culverts, and man-made dams. When these barriers occur in the lower areas of a
watershed, it can close off a very large amount of suitable spawning grounds for important
migratory fish species like the Atlantic salmon.
During the summer of 2014, the SBWA did restoration work at 4 sites throughout the
watershed. The sites where located around water quality sites, and are identified a Pellerin road
(ScdD), St-Philippe (ShdG), Scotch Settlement (ShdB) and Bateman Mill (ShdH).
- Pellerin road had an abandoned beaver dam inside the culvert that was removed, in
addition to the hut that was cleaned (debris moved above the highest water level). Trees
such as white pine, red maples and tamarack where planted along the banks to increase
stabilization.
FIGURE 22: BEFORE AND AFTER OF THE BEAVER HUT AT SITE PELLERIN RD.
- St-Philippe had a beaver dam underneath the bridge and many trees cut from the
surrounding banks. The dam was cleared and approximately 30 trees where replanted.
FIGURE 23: BEFORE AND AFTER OF THE BEAVER DAM AT ST-PHILIPPE BRIDGE
22 Water Quality Remediation and Public Outreach Program Final Report March 2015
- Scotch Settlement had multiple debris jams and pile ups from abandoned beaver dams.
Debris was cleared and trees and willow stalks were planted on the rivers bank, the length
of the site was approximately 100 meters.
FIGURE 24: BEFORE AND AFTER OF A DEBRIS JAM AND SOME FRESHLY PLANTED TREES AT SCOTCH SETTLEMENT
- Bateman Mill also had a beaver dam in front of a culvert, which was cleared and some
trees were planted. The area surrounding of the site is a wetland, therefore water tolerant
coniferous trees were planted.

Electrofishing
As part of our restoration efforts, electrofishing surveys were done at our restoration sites to
establish population densities, so that we can measure the improvements of our restoration with
future electrofishing surveys.

Tern Platform
A colony of common tern in Shediac was displaced after their usual nesting area, a barge at the
Shediac Marina, was disturbed by the reconstruction of the barge with rocks. A floating platform
was placed near Pointe-du-Chêne in the hopes that the colony would adopt it for nesting. The
platform was equipped with wooden tern decoys and a bird song generating machine. The
project was a success, as one couple made a nest with 3 chicks, which we believe all survived to
stage of being fledged.

Biodiversity enhancement for the Town of Shediac
The SBWA has entered a partnership with the Town of Shediac in a native tree planting
project, funded by Environment Canada’s EcoAction program. The project has a goal to plant
more than 500 trees and shrubs that are native to our region, and to build and place at least 60
bird houses within Shediac town limits.
The work began in October, starting with the Millennium Trail, where 30 hemlocks were
planted along both sides of the trail to create a corridor of conifers. A row of shrubs (15 highbush
cranberries) was also planted along a walking trail in the Centennial Park as well as a few rows
of white ash trees. Also in this area, shrubs were planted around the fence of the dog park, a mix
of elderberry and alternate leaved dogwood. We will continue to plant trees and shrubs in other
parks and trails within the town limits next year. We will also be partnering with the MFB
School in their learning garden project “Jardin Pédagomax”, in which we will be contributing
approximately 1500$ in trees and shrubs as part of this biodiversity project.
The bird houses will be built this winter, by partnering with the 4th grade students of MFB
School and Nature NB. They will be placed throughout the town parks. Five models of bird
houses will be built to favor biodiversity.

5.2 Beach Sweep
Each year the SBWA organizes community beach sweeps to fight against shoreline litter that can
detract from enjoyment of coastal environment. This year, the SBWA organized two events
aimed to combat marine litter and contribute to the protection and conservation of our marine
environment. The first beach sweep was held on June 7 to celebrate World Oceans Day,
sponsored in part by the Town of Shediac and Gestion H2O. It was a cold windy day, but we still
had over 30 volunteers, including families and their children.
The weather was more favorable for our second event on September 16th. Students from the
second grade of MFB School in Shediac received a presentation on litter in the environment; the
sources and impacts on wildlife. The 47 student then formed teams with teachers and
volunteering parents, to collect garbage on the coast of the Shediac Marina, at low tide. There
was then a BBQ lunch, courtesy of the Shediac Co-op.

5.3 Hockey net removal
In 2014, the sight of the abandoned hockey net in the Albert-Gallant River has been all too
familiar for the neighbouring residents. It was abandoned on the ice and left to become a
structure fixed on the muddy bottom of the shallow side of the river, visible at low tide. A
request was made to the SBWA to help clean up the site. The field team put on their waders and
retrieved the net, bringing it to the shore at the Home hardware dumpster, who had happily
agreed to dispose of the item.

Education and Awareness
5.4.1 Shediac Market in the Park
The SBWA Information Booth was displayed at Shediac’s Market in The Park every second
week this past summer. Public response was very supportive. Topics of particular interest were
green crab, habitat restoration, water quality, and our tern platform. Our booth also allowed
promoted the SBWA and attracted several new members.
FIGURE 31: AWARENESS SESSIONS AT THE SHEDIAC MARKET IN THE PARK
5.4.2 Homarus Eco-centre at Pointe-du-Chêne
The SBWA works in partnership with Homarus Eco-Center, located at the Pointe-du-
Chêne wharf. We shared two of our summer students with the Eco-Center, to lend a helping hand
in providing presentations and educational activities throughout the summer. The center was
very busy, attracting local people, tourists and summer camp groups. There were approximately
3 000 visitors throughout the summer months.
5.4.3 School Presentations
In March of 2014, the Fish friends program started with the 4/5th grade class of Shediac Cape
School and with the 6th grade class of MFB School in Shediac. Each aquarium held 150 trout
eggs that where raised and then released into local rivers. The students learned about fish habitat
and fish life cycles.
FIGURE 32: TROUT AQUARIUM IN THE CLASSROOM, 2014

CLOSING COMMENTS
The Shediac and Scoudouc Rivers are the largest source of bacteria input in Shediac Bay.
Also, Parlee Beach Provincial Park is an important tourist attraction during the summer months.
It is important to monitor water quality in the watershed and make necessary actions for the
health of our rivers and the bay.
The work performed during the development of the water quality project included different
activities related to water quality remediation planning and public outreach. The water quality
monitoring program is crucial for the management of the watershed. The water quality
monitoring program allowed us to identify problematic areas and water quality trends.
Continuing to perform water quality monitoring and adopt new methods of doing so is very
important to ensure that our watershed is properly managed. Such activities complement
remediation work by determining not only where this work is needed most, but also if such work
is properly accomplished. All these efforts should be distributed on a long period of time in order
to produce accurate indicators of water quality and habitat integrity.
The Status of Shediac Bay and its Watershed – An Introduction has gained momentum
throughout the year and is well recognized by residents. We are working to develop a Strategic
Watershed Management Plan.
The media also plays a huge role in enhancing the association’s profile. Various articles
were in newspapers, radio stations, television to announce our projects and events. The SBWA
has built reliability among the community. When a project is taking place, we take the
opportunity to make interviews with different media. This way, the public can refer to us as a
complete group performing many projects to aiming to maintain the water quality. The SBWA
also installed their booth at various community events during the year. Hosting events such as
the beach sweeps also served to raise awareness and the association’s visibility while helping
members of the community realize that their participation can have an enormous positive impact
on our watershed.
Furthermore, developing and implementing an annual environmental education program
with local schools has proven especially useful in sensitizing our youth, teachers and parents on
watershed issues and the importance of protecting our waterways. Children responded very well
to our presentations and the schools greatly appreciate our work.
Directly working with various governmental agencies has helped in reaching many
stakeholders. The Department of Fisheries and Oceans, for example has assisted the SBWA in
different projects such as Invasive aquatic species identification with the public. Increasing our
visibility is crucial for the long-term development of a watershed group. We believe that we can
greatly contribute at multiple levels for the management of bays and watersheds. The SBWA is
engaged to respond to environmental concerns and complaints by contacting appropriate
governmental agencies to verify regulations and permit compliances. In some cases formal
complaints are directed to the concerned governmental bodies. The Department of Fisheries and
Oceans and Environment Canada are contacted when sedimentation issues or fish habitat
deterioration are observed.
The SBWA also enjoyed the support of multiple volunteers and members during the year.
Their support always ensures the stability of the group and allows us to continue to develop great
educational activities.
Finally, the Water Quality Remediation and Public Outreach Program was very successful
and we accomplished many activities and events over the past year. Many endeavours remain to
be completed due to the magnitude and scope of the remediation work left to be tackled.
The SBWA is definitively making a big difference in the community. Monitoring results
show modifications in stream water quality. Our work needs to be performed on a long-term
basis in order to obtain positive results. However, we are confident that our group can enhance
and maintain the water quality and a healthy community for future years since action taken at a
community scale has proven to be successful.

Le crabe vert poursuit sa colonisation au
Nouveau-Brunswick
Publié: 17 h 26 min, Mercredi 30 juillet 2014 par Jean-Marc Doiron
La population du crabe vert, une espèce envahissante, continue de grandir dans la baie de Shediac. - Acadie
Nouvelle: Jean-Marc Doiron
Marcel LeBlanc, un employé étudiant de Shediac, vérifie un casier de crabe vert. Son travail permet de tenir compte
du taux de population de l’espèce envahissante dans la baie de Shediac. – Acadie Nouvelle: Jean-Marc Doiron
SHEDIAC – Le crabe vert poursuit sa colonisation des côtes du sud-est du Nouveau-Brunswick. Le crustacé
envahissant représente une menace pour les espèces qui habitent les estuaires.
Dans un petit bateau du ministère des Pêches et des Océans, mercredi, le gérant de l’Association du bassin versant
de la baie de Shediac, Jim Weldon, a vérifié une dizaine de casiers conçus pour attraper le vorace crustacé.
En 24 heures, certains des casiers avaient attrapé plus de 20 crabes verts.
7 APPENDIX A – MEDIA COVERAGE
«Les nombres sont légèrement à la hausse à comparer à l’an dernier, selon nos premières indications. Nous voyons
de plus petits crabes cette année, ce qui veut dire qu’ils survivent bien», nous apprend M. Weldon.
«Dans le dernier mois, ils ont presque doublé de grosseur. Ils sont très contents de l’alimentation fournie par les
algues de la baie.»
Il y a trois ans, le premier crabe vert a été trouvé dans la baie de Shediac. Depuis, entre 100 000 et 5 millions de
crabes verts, mesurant de six à neuf centimètres de largeur, y habitent, selon les estimations de M. Weldon.
Originaire d’Europe et d’Afrique du Nord, le crabe vert est considéré comme l’une des cent pires espèces exotiques
envahissantes au monde. Au début des années 1990, il a été aperçu pour la première fois dans le golfe Saint-Laurent.
Il est reconnu pour son habileté à survivre à de grandes variations de température (de 0 à 30 degrés Celsius) et son
extrême voracité.
Afin d’illustrer leur agressivité, la directrice scientifique d’Homarus, la docteure Dounia Daoud, a introduit un
poisson mort dans un aquarium contenant des crabes verts. En l’espace de quelques secondes, ils se sont rués vers
l’appât, bouillonnant comme des piranhas. Un des crabes a même grimpé sur le poisson et s’est dirigé vers les doigts
de la chercheuse, qui tenait toujours le poisson, avant qu’elle le secoue.
«Ce crabe-là est tellement résistant et se reproduit tellement vite qu’il pourrait très bien, un jour, étendre son habitat.
J’aimerais qu’on étudie ça dès maintenant, afin qu’on ne soit pas pris avec des crabes verts qui envahissent toutes
nos eaux», a-t-elle affirmé.
L’introduction du crabe vert dans l’écosystème menace les populations de palourdes, de coques, de moules,
d’huîtres et d’anguilles, entre autres.
«Les pêcheurs d’anguilles, par exemple, ont des casiers un peu partout dans la baie. Les crabes entrent, en grand
nombre, dans les casiers à anguilles, et mordent les anguilles qui perdent leur valeur», nous apprend M. Weldon.
Selon M. Weldon, la population du crabe vert, qui n’a pas de prédateurs naturels dans la région, aurait colonisé au
moins jusqu’à Bouctouche. Ce serait vraisemblable d’imaginer qu’un jour, à chaque endroit ou une rivière coule
dans le détroit de Northumberland au sud de Miramichi, on y trouvera une population de crabe vert.
Pas de risque pour les nageurs et les homards.
Les amateurs de la plage et les pêcheurs de homard n’ont pas à s’inquiéter que le crabe vert bouleverse leur routine.
Le vorace crustacé habite les estuaires et les eaux peu profondes où poussent de longues algues. Il ne colonise
habituellement pas l’habitat des homards, soit les eaux de 5 à 10 mètres avec un fond rocheux ni l’eau des plages,
qui est couverte de sable.
«Le crabe vert, on commence à l’étudier, mais il n’est pas encore une menace pour le homard. Ils n’ont pas le même
habitat», a affirmé la chercheuse Dounia Daoud.
«Les eaux plus chaudes et peu profondes, avec leurs lits de plantes marines, contiennent beaucoup de nourriture
pour les crabes verts.»
À l’avenir, si la population du crabe vert croît de façon exponentielle et que l’habitat devient surchargé, ils
pourraient étendre leur territoire jusqu’aux eaux plus profondes où se trouvent les homards, selon Mme Daoud.
Green crab may soon be a diner's delight
UPEI, DFO pilot project aims to harvest, market the invasive species as a
delicacy
CBC News Posted: Sep 01, 2014 2:57 PM AT Last Updated: Sep 01, 2014 2:57 PM AT
Green crabs arrived in P.E.I. about 15 years ago.
Finding ways to harvest and market the destructive green crab as a delicacy to reduce the crustacean's impact on the
local shellfish industry is being investigated by the University of Prince Edward Island.
The green crab is an invasive species that has been multiplying exponentially since arriving in P.E.I. 15 years ago
and UPEI researchers have been trying to figure out how to get rid of them.
'You more or less batter them up and deep fry them.'- Luke Poirier, UPEI graduate student
"The green crab is a concern for the shellfish industry and for the government," said UPEI biology professor Pedro
Quijon.
"They can eat an insane amount of little oysters very, very quickly, and up-rooting eelgrass, for example, which is
really bad."
But now, UPEI is working with the federal Department of Fisheries and Oceans on a pilot project that would
promote the crab as a food item and potentially limit the negative effects it has on other marine life.
Graduate student Luke Poirier is researching the successful green crab market in Italy, hoping to eventually see a
similar market established on P.E.I.
"The idea is that you fish them when they moult, which is how crabs grow, and they're soft to the touch," said
Poirier.
"And you more or less just batter them up and deep fry them, similar to like an appetizer or something at a
restaurant."
Group searches for rare freshwater
mussel near Shediac
Brook floater mussels are considered endangered in the United States

The Shediac Bay Watershed Association is looking for a rare fresh water mussel around Saint-Philippe that was
spotted in the area in 2005.
The brook floater population has dwindled in the United States, making the mussel's home in New Brunswick and
Nova Scotia an important stronghold.
Rémi Donelle, the manager of the Shediac Bay Watershed Association, said a few dozen of the rare mussels were
found in the Shediac area in 2005 when they were last studied.
"We are hoping to find some, we should,” Donelle said.
“It is a rare mussel, so there was a few found in the 2005 study, so we're hoping to find, at least on some sites, this
rare mussel."
Donelle is using an unconventional looking device to find the rare mussels. He has a black garbage can with
plexiglass taped to the bottom.
It may look odd, but it does allow Donelle to search for the brook floaters.
However, Donnelle said the watershed association hasn't found any brook floaters yet this summer.
"We don't know if that's because of change in the habitat or if it's been misidentified in the past or if we just haven't
seen it yet," he said.
Donelle said the rare mussel is considered an endangered species in parts of the United States and it's being
considered for the species of concern list in Canada.
But Donelle said he hopes the mussel turns up in the Shediac area. He said that would be a sign of healthy water
systems and it could increase the chance of the brook floater’s survival.
If others find these mussels, the watershed association's manager has some simple advice.
“If they do see mussels just leave them there, they can live really long, they can live a few hundred years if they are
undisturbed, they would be edible, but they wouldn't be good,” Donelle said.
If the rare mussels are found, the watershed association will start work on habitat protection and restoration in the
fall.
Brook floater mussel a rare sight in
Shediac Bay
A 2005 survey found the brook floater mussel in 10 locations along the Shediac
River, no sightings this summer

A rare freshwater mussel, already a species at risk according to the Department of Fisheries and Oceans, has become
rarer in Shediac Bay.
In 2005, a survey found the brook floater mussel in 10 locations along the Shediac River, but this summer passed
without a sighting.
Jolyne Hébert spent about 60 hours searching riverbed bottoms this summer, looking for the brook floater.
The environmental technician at the Shediac Bay Watershed Association says it was discouraging.
“We started to doubt whether or not we were actually going to find them, we started to, if you will, lose hope a little
bit,” she said.
The rare mussel didn't appear and that was surprising given the information collected almost 10 years ago.
“There were some sites where there were reported up to 27 even 30 brook floaters that they had found so we put a
higher priority on those sites,” Hébert said. “When we did the sweep we thought it was a bit strange that we hadn't
seen one.”
Rémi Donelle is the project manager and says the brook floater is only found in the Northeastern United States, parts
of New Brunswick and Nova Scotia.
Lack of mussels could be a sign
“These rivers were considered to be one place where there was a good population of brook floaters so if not, then it
means the species is rarer than first thought,” he said.
Donelle says the missing mussels are a cause for concern, because a healthy population is usually a sign of healthy
rivers.
“The freshwater mussels, they need a good clean habitat, to live, to reproduce,” he said. “They need fish, so if there
is no mussels, or if there is a decline in the mussels it might raise flags, warning flags that the environment might be
degrading.”
The group says it will continue its search next summer.
Shediac group aims to relocate colony of
common terns Shediac Bay Watershed Association hopes a new platform will encourage the
terns to stay in the area

A group in Pointe-du-Chêne is hoping to entice a displaced colony of common terns to stay in the bay after the barge
the birds were using as their summer home was replaced last fall with a rock wall.
The Shediac Bay Watershed Association installed a floating platform on the weekend, complete with guard rails for
clumsy chicks, shade and a recorded tern call to attract the birds.
Rémi Donelle, the manager of the Shediac Bay Watershed Association, said the group does not have a lot of time to
waste if it wants to successfully lure the terns to the platform.
He said if the birds leave the area to nest elsewhere, it is unlikely that they will return to Shediac Bay.
“We really want to keep those birds in the Shediac Bay because it's something that's quite rare, tern colonies, they're
not found everywhere,” he said.
Donelle said he hopes the recorded tern call that is on the platform will attract the birds to the new location. It seems
to be working, he said.
“I can see that birds are hanging around way more,” he said.
But Donelle said he won't know if the new colony has been successfully relocated until eggs are laid.
“The terns arrived maybe two or three weeks ago, they'll be nesting anytime so, in the next three to four weeks we
should know if we've got a success or not,” he said.
If the terns do choose to nest there, Donelle said the watershed association will try to expand the platform to
accommodate a full colony.
Terns have caused controversy in the past in southeastern New Brunswick. In 2009, boaters and birders sparred over
the terns’ nesting habits.
Boaters were upset by the mess the birds were leaving behind.
Harper Government invests in Round II
Recreational Fisheries Conservation Projects
in Southeast New Brunswick
October 20, 2014
The Government of Canada to invest up to $5.5 million to restore recreational fisheries habitat through the National
Conservation Plan
Shediac, New Brunswick – On behalf of the Honourable Gail Shea, Minister of Fisheries and Oceans, Robert
Goguen, Member of Parliament for Moncton-Dieppe-Riverview, today announced that, under the second round of
the Recreational Fisheries Conservation Partnerships Program, the Government of Canada will provide up to
$74,000 for three projects to conserve fish habitat in Shediac, Cap-Pelé and Saint-Louis-de-Kent.
The Recreational Fisheries Conservation Partnerships Program was announced in Economic Action Plan 2013 to
support fisheries habitat restoration projects led by recreational fishing and angling groups, as well as conservation
organizations. Given its early success and high demand, an additional investment in Economic Action Plan 2014
increased the funding available through the program to a total investment of $25 million.
On May 15, 2014, the National Conservation Plan was launched to provide a more coordinated approach to
conservation efforts across the country. Since 2006, the Government of Canada has taken important steps to
conserve and restore our country’s natural environment and connect Canadians to our rich natural heritage. To date,
the Recreational Fisheries Conservation Partnerships Program has invested nearly $6 million (Round I), in 94
fisheries habitat restoration projects across Canada and funding to support up to an additional 128 projects (Round
II) is currently underway. Details about the program can be found on the Program’s Web site (www.dfo-
mpo.gc.ca/pnw-ppe/rfcpp-ppcpr/index-eng.html) where you can also sign up for updates.
Quick facts
Here are the details on the three projects:
•Groupe du bassin versant de la région de Cap-Pelé Inc. – Restoration of the Tedish River including river clean-up
(waste, wood debris, old beaver dam), removal of major barriers to migration, reduction of sedimentation, planting
of seedlings on damaged river bank and encouragement of community to participate in the restoration.
•Shediac Bay Watershed Association – The removing of beaver dams and the replanting of river banks of the
Scoudouc and Shediac Rivers to avoid bank exposure after the dam removal.
•Friends of the Kouchibouguacis – The removal of a degraded creosote wall and the restoration of the shoreline
namely by planting approximately 250 trees, shrubs and plants.
Under the first round of the Recreational Fisheries Conservation Partnerships Program, more than $521,000 had
been made available for 12 projects in New Brunswick.
Quotes
“Our Government is committed to supporting the individuals and organizations who are working along the shores of
lakes, rivers and streams across this country to protect and restore fishing habitats for future generations.
Recreational fishing is an important economic activity which attracts thousands of visitors to Canada and contributes
billions of dollars to our economy every year. The projects funded by the Recreational Fisheries Conservation
Partnerships Program will benefit Canadian communities for years to come.”
The Honourable Gail Shea, Minister of Fisheries and Oceans
“Today we have taken yet another step to support the individuals and organizations who are working to help restore
the rivers of Shediac, Cap-Pelé and Saint-Louis-de-Kent. Projects like these are helping to restore fishing habitats
within our communities while also supporting a popular New Brunswick recreational activity. These projects will
benefit our community for years to come.”
Robert Goguen, Member of Parliament for Moncton-Dieppe-Riverview
