• Leave part of our time for visualize how the future could be, how thinks can orhave to change disturbing dramatically theway how we do things.

• Define how we can be in that future

• Organize the efforts to develop the futureand generate new answers.

• Plan for the application of the achievementsof your search for answers at the right time.

• Start the application of your efforts, • Be prepared for corrections• Be prepared to see opposition top the new

• Be unprepared for problems thatseem to appear unexpectedly.

Some history of the application of recirculation in Some history of the application of recirculation in Chile Chile

Small installation for turbot in Tongoy•Formulation of development project in Fundación Chile

•Small scale RAS designed and built •Bigger scale RAS designed and built • & Creation of INACUI• Success of Smolt produced in RAS

•Camanchaca 1rst industrial application FRY•Marine Harvest FRY Unit

•Marine Harvest Smolt farm

•Application to fish transport

•Marine Harvest pilot RAS

Characteristics of fresh waterCharacteristics of fresh water

Abundant fresh water but

•Temperature to high for incubation 10 – 16°C•Temperature to low for fry and smolt production 5°C

Contains Level seen in source

•High levels of CO2 5 – 20 mg/L•High levels of N2 110 – 130% saturation•Low in O2 3 mg/L•Low hardness <30 mg/L•Low alkalinity <5 mg/L

•High level of Aluminium AL+3 0,5 - 1,2 mg/L•High level of Fe+2 0,5 - 3 mg/L

Recirculation of water reduce the energy requirement

• Cooling water for incubation in 90 - 95%• Heating water for fry and smolt in 60%

Also:• RAS have a built in solution for the high level of CO2• RAS have a built in protection against N2 high level• RAS do not depend on O2 in the make up

• Correcting Alkalinity and Hardness only can be done using RAS,otherwise, the limitation comes from the quantity of chemicals needed.

• Al+3 can be controlled with the addition of 6,8 mg/mg of Sodium silicateNa2SiO3 per 1,0 mg of Al+3, forming innocuous Al2(SiO3)3

• Fe+2 can be adsorbed in a Ionic exchange resin or, • Fe+2 can be oxidized to Fe+3 insoluble, and filtered in a gravitational

sand filter.

The applicability of all of these solutions derivatesfrom the reduction of water use

Improving fish transportImproving fish transport

Environmental conditions in the fish transportEnvironmental conditions in the fish transport

• In Chile, transporting juvenile fish is fact of life.• Fish are transported more than ones in their FW period

• Typical transport by road:

• density of 40-60 kg/m3• O2 injection (mostly without automatic control)• Time of transport could easily vary from 6h to 50h

•Water is change during the trip.(no controlling the water quality and conditions)

• TAN and CO2 accumulates during transportation• NH4+ predominates due to low pH generated by CO2


4 tanks of 3000L each5 tanks of 3000L each

1350 kg of fish / (track + trailer)For example:22.500 fish of 60g

200 million smolts needs over 15.000 tripsTanks are fiber glass reinforced plastic, of difficult sanitization

Idea is:

• Improve the environmental conditions for the transport• Increase productivity of the investment• Reduce variable cost of transport• Reduce risks of transmission of diseases from one

transport to the next

A plan for building a full scale demonstration unit was achieve in 2004As JV of FCH, private companies, and money for innovation from CORFO.

The plan was to install a big system for:

•Experiment in a big scale•Take experience and visualize opportunities for improvement•Generate an expertise in a selected groupfor engineering new plants, and improve the solutions.

INACUI was created in 2003
