Facts & Benefits

FLOW-THROUGH Systems

 

The Flow-through system is the traditional way of production.

Facts

Benefits

Open to disease from intake water
Temperature depend fully on intake water
Low efficiency on salt treatment
Well known technology
When establishing new flow through farm, investment / kg production capacity is
circa the same as a new re-circulation system.
Very high cost both in investment and running costs to sterilize intake water.
If heating - very high heating costs
Site placement depends on large amount water availability

Possible full oxygen control
Possible full system monitoring
When using existing facility - no investment

 

 



 


 Re-Use Systems

Re-use gives you a fast track to increased production. DOUBLE YOUR PRODUCTION at low costs, and have your system fully prepared for expanding your fish farm to a fully re-circulated system at a later stage. By re-using your present available water intake 1 or 2 times, you can in most cases double your production in your existing fish tanks. Re-use systems designed in the right way, is the first step to Re-circulations and the gateway to all the benefits available in modern fish farming.

Facts

Benefits

Temperature depend fully on intake water
Relative high cost both in investment and running cost to sterilize intake water
Low efficiency on salt treatment
Well known technology
When establishing a new re-use farm, investment / kg production capacity is circa the same as converting existing
tanks to re-circulation.
If heating - very high heating costs
Site placement depends on large amount water availability

 

 

Full oxygen level control
Full system monitoring
Low manpower need
Low investment
Low energy costs
Reduced water usage by 50 - 65%

 

 

 

 



 

Basic Re-Circulation Systems

Re-circulation gives you unlimited possibilities. PRODUCE FISH AT ANY LOCATION as long you have access to minimal water supply.
Example: 1000 ton production per year - water usage 8 - 10 liter/second.
INCREASE YOUR PRODUCTION BY 4-6 TIMES in your existing tanks, and cut your production costs by 30-50 % and profit from all the BENEFITS in Re-circulation technology. Re-circulation gives you all opportunities to supply your customers FISH FREE OF DISEASE AND CHEMICAL RESIDUES - exactly what customers want.

Facts

Benefits

Intake water = 0,5 - 25% / day of total volume of fish tanks
Investment same or lower per kg produced fish - compared to flow through and re-use.
When adding salt, concentration is easy kept for many days - due to low water change.
Possible to increase temperature to 19 degrees Celsius in order to cure IPN outbreak
The low amount of intake water, makes it affordable to sterilize 100%.
The low amount of effluence makes it easy to handle and to comply with environmental legislations.
Production planning becomes easy, as there is no dependence on weather conditions.
Oxytetracycline have no negative influence on bio filters.
More than 20 years of experience with re-circulation - secures well proven technology
Free choice of site placement - need no river.
Compared with Flow Through and Re-use, the production cost in Re-circulation are 30 - 50% lower.

Low investment
Full disease control
Full temperature control
Full salinity level control
Full water quality control
Full smoltification control
Full oxygen level control
Full effluence control
Full freedom of site location
Full production year round
Full system monitoring
Full management support
Low production costs
Low or no mortality

 

 



 

Closed Re-Circulation Systems

Re-circulation gives you unlimited possibilities. PRODUCE FISH AT ANY LOCATION as long you have access to minimal water supply.
Example: 1000 ton production per year - water usage 0,25 liter/second.

INCREASE YOUR PRODUCTION BY 4-6 TIMES in your existing tanks, and cut your production costs by 30-50 % and profit from all the BENEFITS in Re-circulation technology. Re-circulation gives you all opportunities to supply your customers FISH FREE OF DISEASE AND CHEMICAL RESIDUES - and that is what customers want.
