What is intensive Recirculation Aquaculture? Indoor Recirculation Aquaculture System are land-based fish farms, which allows all year round control and delivery of fish. Whether the facility will use fresh water, brackish or a marine water, an R. A. S works on the same principles. The system can achieve optimal temperature and optimal and stable production all year round, independent of seasonal variation, location, climate and environment. 2 1 Water to filtration Tanks in various sizes, where fish is grown to consumption size. Solids like uneaten feeds and faeces are removed by the mechanical filtration. Water to fish tanks 3 5 Re-oxygenate the cultured water to super saturated level. Bacteria consume the ammonia(NH 4), which convert into nitrogen (Co 2) and is released into the atmosphere. 4 UV , ozone and upflow filtration to optimize the water quality.

Why to establish intensive re-circulation fish farms? Legislation Worldwide the environment restrictions and climate change needs solutions. R. A. S. has high production of quality fish on a relatively small area, since high density and a high growth in the controlled environment. Reduced risk of diseases , monitoring control and low mortality rates The water quality is treated to achieve the desired quality. The effluent can be reduced to a minimum, and therefore be controlled. Water consumption R. A. S is the solution. Over-fishing of waters, catch regulations or catch declining. for R. A. S the regualtions are very clear. In several countries water is a major problem while there is a short of rain plus evaporation of water in ponds and lakes, In R. A. S the consumption of water is limited. Average 5% per day of total water volume Quality Climate It might not always be possible to get all year round wild catch quality fish. The consumer however demands all year round “quality fish”. R. A. S you can deliver 365 days per year quality fish. Free of antibiotics with clear ”tracking label” Polution In some areas the optical water is wasted because of continues pollution. R. A. S is enviromental friendly, and water quality is under control Land In several countries the climate is too cold or too warm. In R. A. S all parameters are controlled and fish is growing in optimum conditions. In relation to open culture; in R. A. S fish grows fast in a relatively small area. Species can be grown outside the natural habitat.

what to keep in mind before starting a fish farm? q. Enough willingness to give up a secured life for an unsure future. The job of fish farmer is interesting and the profits are usually good but working with life stock could be a risk. q. Enough financial backing by own capital and/or bank, eventual subsidies must be an extra never the foundation of a business. q.
