ABSTRACT:
A method of and installation for breeding sea-water creatures in tanks according to which algae and plankton species forming a preferred food of the sea-water creatures to be bred are grown in feed tanks while the salt content of the water in the feed tanks is adjusted by controlling the sea-water supply to the feed tanks in conformity with the evaporation taking place in the feed tanks. Thus grown plankton species are released from the feed tanks into fish tanks into which the desired sea-water species are introduced in the form of hatches. The fully grown sea-water creatures are withdrawn from the fish tanks and either are eventually sold or a part only is sold while another part as desired breeding stock is conveyed into one or more containers for spawning. The obtained spawn are transferred into one or more additional containers for hatching. Sea-water is in a closed circuit passed through all of these containers after having been filtered. After the hatch has reached a required degree of maturity, it is transferred into the fish tanks.
