The water recirculation techniques used for aquaculture is not only the way forward in countries where environmental conservation is highly emphasized; the technique is also
used to secure a higher and more staple aquaculture production with less diseases and better ways to control the hatchery parameters that influence growth. The strong
environmental restrictions to minimize pollution from hatcheries and aquaculture plants in Northern European countries have sparked a rapid technological devel opment of the
recirculation technique. This promotes environmentally sustainable aquaculture and also implies that hatcheries no longer necessarily need to be placed in pristine areas near
rivers. Now they can be built almost anywhere a much smaller source of clean germ free water is available.
