Abstract—This study aimed to identify the species composition
and abundance of marine fishes in selected landing areas of Northern Samar, Philippines; determine their abundance; their local names; and identify the fishing gears used. Sampling areas included Balicuatro Area, Central Area, and Pacific Area. Data were gathered using translated questionnaires. Fishermen and fish vendors were asked about fishing gears, local names of fishes, species caught and their abundance. The landing areas were visited once every three months, from January to December 2013. There were 102 species of fish belonging to 66 genera, 23 families, 3 sub-orders, 2 orders, 2 sub-classes, and 2 classes. The most abundant fish species is Atule mate Cuvier (yellow-tailed scad), while the least abundant is Plectropomus leopardus Lacepede (coral grouper). There were more fishes in the Balicuatro Area, than in the Central and Pacific Areas. The simple hook-and-line was the commonly used fishing gear of the fishermen.
Keywords—abundance, fishing gears, marine fishes, species composition
I. INTRODUCTION ISHES are cold-blooded animals, typically with backbone, gills, fins, and lungs. Best estimates from 15,000 to
17,000 recent species. There are many kinds of fishes and they come in different colors, shapes, and sizes [1].
The Coral Triangle, which includes the Philippines, is the heartland of marine biodiversity. There is relatively poor documentation for most groups other than fishes and corals. Even with fishes, there is a scarcity of information from specific locations within the Triangle [2].
In the coastal areas reside about 59% of the country’s total population and this is where about 70% of the 1,525 of the municipalities in the country, including 10 of the largest cities are located. This indicates how the lives of most Filipinos are closely linked with the sea and its biodiversity [3].
II. OBJECTIVES The objectives of this study are: 1. To identify the species composition of marine fishes in
the landing areas of Northern Samar, Philippines;
Divina Galenzoga is with the College of Science, University of Eastern Philippines, Catarman, Northern Samar 6400 Philippines (e-mail: [email protected]).
Geraldine Quiñones is with the College of Science, University of Eastern Philippines, Catarman, Northern Samar 6400 Philippines.
2. To determine the abundance of marine fishes in the landing areas;
3. To determine the local names of marine fishes sold in the landing areas; and
4. To identify the fishing gears used by fishermen in catching the fishes.
III. METHODOLOGY Northern Samar lies in the northeast portion of the island
of Samar, Philippines with longitudes of 12° 15’ - 12° 45’ and latitudes of 124° 15’ - 125° 30’. It is one of the six provinces comprising Region VIII (Eastern Visayas). The province consists of 24 municipalities, i.e. 15 coastal towns, 5 island towns, and 4 interior towns. Catarman is the capital town of the province of Northern Samar.
Sampling areas included the coastal towns and landing areas of Allen and Lavezares (Balicuatro Area), Catarman and Mondragon (Central Area), and Pambujan and Laoang (Pacific Area).Data were gathered using semi-structured interview questionnaire in English and translated into Samarnon dialect, about the names of fishes, their abundance in the landing areas, their local names, and the fishing gears used by fishermen. The interviews were conducted to 60 fishermen (10 per landing area) and 60 fish vendors (10 per landing area) during the course of one year, i.e. January – December 2013. Visits in the landing areas, where freshly-caught fishes are sold, (local name: talipapa/small market) were done quarterly. During the sampling, fish species composition and abundance were recorded.

B. Abundance of Marine Fishes in the Landing Areas During the first quarter of the year, i.e. January-March,
fishes are less abundant since it is the time of year when ice and snow from the temperate parts of the world start to melt. The marine waters are cold, and some of the tropical fishes are still on their hibernation mode. While in the tropical countries, this is the season of spring time where the flowers begin to produce blooms and leaves again. The waters are still cold.
During the second quarter of the year, i.e. April-June, is the time when fishes are on their most abundant time of the year. Juveniles and young adult fishes, and all stages of fish life go out because it is summer time. Young fish start to grow and go out from their abode areas. The marine waters are warm and many other animals are out to sea and start again to enjoy the warm sunshine after the cold season.

During the third quarter of the year, i.e. July-September, some species of tropical fish start to hide themselves and be rested on their places of abode because the marine waters start to become colder. Fish composition and abundance become less.
During the fourth quarter of the year, i.e. October-December, some species of marine organisms are not found on the landing areas anymore because either they are dormant or hibernating; or are resting because they are on their gestation period. Although fishes are still found on the landing areas, but of fewer number.
Trevallies, jacks and their relatives are well represented in tropical and temperate seas with about 140 species. They are powerful swimmers and are encountered in schools. Most are closely associated with reefs and may patrol huge areas, i.e. several kilometers in search of food, such as octopus, squids, crustaceans, and other fishes [2].
The most abundant fish species belonged to Family Carangidae, i.e. Atule mate Cuvier (yellow-tailed scad/finlet scad). This fish species can be found in all the landing areas of the province anytime of the year in large quantities. This species, found throughout the region, inhabit coastal waters, forming large schools, distinguished by clear fleshy eyelid covering most of the eye except narrow slit in the center. It is implied that since this fish species is abundant, the status of the coral reefs in the province is still in their normal condition.
The least abundant fish species belonged to Family Serranidae, i.e. Plectropomus leopardus Lacepede (coral grouper/Leopard cod). This fish species was sold in the landing areas during the second quarter of the year from April to June (spring-summer time); and only in a small number. They inhabit coral reefs, distinguished by numerous small round spots on head and body, found in the Philippines and throughout South East Asia. They are called as group – groupers. They are the dominant element of the fish community on all coral reefs especially the larger species. They are important table fish at many localities and they play an important role in the reef’s food chain [2].
Although majority of the fishes sold in the landing areas are caught from the nearby coral reefs, pelagic seas, and municipal waters, other fishes are harvested from the fishponds of fish dealers/businessmen in the province, such as Chanos chanos (milkfish/bangus). The abundance of fishes in the landing areas was measured by approximating the total number of kilos, i.e. 1 kilo equals 1000 grams, and the kind of species that was present during the sampling period. Together with the interview, the fishermen and fish vendors approximate the number of fishes (by kilo) present on their tables. Each fish vendor/fisherman owns one table in the landing area, i.e. talipapa. The selling of fishes occur every day every seven to twelve o’clock in the morning, and one to six o’clock in the afternoon.

D. Fishing Gears Used by Fishermen in Catching Fishes The fishing gears used by fishermen in catching the fishes
during the time of sampling were: simple hook & line (kawil), which was commonly used, multiple hand line (lagolo),
bottom set gill net (patitig), bottom set long line (kitang), spear with light (panulo/sarapang), spear gun (pana), crab/fish trap/pot (panggal), octopus/squid/fish jig (rambo), which was seldom used, beach seine (sagad), and round haul seine (lawagan).

a – always/often used b – moderately/fairly used c – seldom/rarely used
1. Simple Hook and Line (kawil) The most traditional form of fishing gear is the simple
hook and line, which is basically made with one or two hooks. This kind of fishing gear is the most common since it can be used in both shallow and offshore waters. A basic hook and line is made of a hook suspended to an extended mainline averaging 100m in length, usually reeled to a homemade bamboo or wooden cylinder. It is the cheapest form of all the cited fishing gears.
2. Multiple Hand Line (lagolo) This type of handline uses multiple hooks suspended with
equal distance to a mainline. Artificial bait made of silk thread and bird feathers are used. The basic operation of the gear involves tugging the line in a regular up and down motion. The time of operation typically falls within dusk and dawn periods where a slight portion of the sun lights the sea surface. During these periods, the artificial bait is said to be the most attractive to pelagic fish. This fishing gear is used second to simple hook and line.
3. Bottom Set Gill Net (patitig) This type of fishing gear is specifically designed to catch
demersal fishes. It is generally constructed at 1-5m in depth. Built with at least 1-10 panels, the gear may be set at depths of 2-10m. Each panel is constructed with an average of 1m in length. The gear is normally employed in an overnight use to a maximum of 24 hours. It can also be operated an hour before the net is hauled and relocated to another area for its next use.
4. Bottom Set Long Line (kitang) This is a fishing line that uses at least 40–100 hooks
suspended along the length of a mainline primarily to catch

demersal fish species. This gear is usually setting the line from shallow to deep waters. A typical outfit is usually installed and kept in a box, and the hooks are placed individually in gaps along the frame of the box to case the laying of baits. In some fishing grounds, the fishermen cannot wait until hauling to avoid loss of gear due to theft.
5. Spear with Light (panulo) This is also another traditional fishing practice used by the
fishermen. The fishermen use a gas/petroleum/gas-fuelled lamp as a source of lighting and a spear to gather fishes. The spear is basically made of a wooden pole with sharp steel tips at one end. It is normally used in a shallow area to catch inactive fishes during night time.
6. Spear Gun (pana) The spear gun consists of a homemade wooden gun with a
rubber sling. The gear is singularly pointed usually with a suspended nylon rope long enough to keep the device retrievable. This gear is complemented with diving implements like makeshift goggles (silip) and flippers (panyapak) to assist the diver during the deep fishing pursuit.
7. Crab/Fish Trap/Pot (panggal)
A typical pot is made with a simple single apical non-returning valve which serves as the entrance of a crab/fish. The gear is often baited with frog/worm meat placed at mid-section usually contained in a receptacle to ensure that it is not consumed. The gear is usually set at 6-10m intervals in depths of 5-20m. Gear soaking usually takes overnight.
8. Octopus/Squid/Fish Jig (rambo) This gear is designed specifically to attract and catch
octopus/squid/fish. The gear is made of lead which is shaped into a fish, with added appendages on the sides, purposely to entangle an octopus/fish squid. It is made with or without hooks which help catch the prey.
9. Beach Seine (sagad) Beach seine is a large fishing net made to hang vertically
in the water by weights at the lower edge and floats at the top with an average of 100m stretch panel of netting. At the center, a conical end is fitted to a length of 10m, usually bearing fine-meshed netting. The operation of the gear is traditionally done on desired sandy beaches operating with a maximum of three hauls. Eight to twelve persons may be involved in an operation. In some areas, beach seine is a set and hauled offshore, employing a non-motorized banca as a platform, while a motorized boat maneuvers and guides the non-motorized vessel to the desired offshore area.
10. Round Haul Seine (lawagan) This practice of using round haul seine as a fishing gear is
used by a group of fishermen in a coastal area. The gear generally consists of a conical lift net with 5-7m in length. A fine-meshed net is usually adopted for the gear, which catches
primarily small varieties of fishes like anchovies, scads, etc. The net is suspended with rope support at each side leading to the vessel. Operation of the gear involves a large mechanized boat. The group of fishermen is headed by a master fisher (manulong) and the mechanic (makinista). Each vessel (lawagan) is complemented with a regular 10-12 crew men (bugador). The vessel has big lights that require 2-3 hours for accumulating a school of fish before the harvest (pagkalat) is initiated.
V. CONCLUSIONS There were 102 species of marine fishes found in selected
landing areas of Northern Samar, Philippines. They belonged to 66 genera; 23 families; 3 sub-orders; 2 orders; 2 sub-classes; and 2 classes.
The most abundant species of marine fish sold in the landing areas during the time of sampling belonged to Family Carangidae, i.e. Atule mate Cuvier (yellow-tailed scad/finlet scad). They were present in all the landing areas anytime of the year in large numbers, while the least abundant fish species belonged to Family Serranidae, i.e. Plectropomus leopardus Lacepede (coral grouper/leopard cod), which can be found only in selected landing areas during the second quarter of the year (i.e. April–June) in small numbers.
The local names that were identified by the older residents, fishermen, and fish vendors of the coastal areas were mostly based on the families of the marine fishes.
The fishing gears used by fishermen in catching the fishes during the time of sampling were: simple hook & line (kawil), which was commonly used, multiple hand line (lagolo), bottom set gill net (patitig), bottom set long line (kitang), spear with light (panulo/sarapang), spear gun (pana), .crab/fish trap/pot (panggal), octopus/squid/fish jig (rambo), which was seldom used, beach seine (sagad), and round haul seine (lawagan).
VI. RECOMMENDATIONS 1. Further studies about fish abundance and diversity
especially in the 5 island towns of the province. 2. Freshwater fishes should also be included since there are
many large rivers in the province. 3. Enforce implementation of laws and orders especially for
the marine resources in the province. 4. Municipal and provincial governments should find
alternative sources of livelihood, as sources of income, for the fishermen, therefore lesser dependence of the sea.
5. Conservation and preservation measures of marine resources be adopted by the Local Government Units.
