Installation for rearing fish with water-stable fish food

摘要

The installation has a feed device (1) which is provided with floating bodies (4, 4'). The floating bodies (4, 4') make it possible to maintain a constantly uniform water level in the feeding place. In operation, the fish feed (13) is introduced via a filter (7), a current of air from a conduit (2) keeping the feed particles (13) moving and supplying the fish with oxygen for breathing. The fish, in particular predatory fish, eat the moving feed (13), leave the relatively small feeding place and defecate outside the feeding place. The excrement (14) collects under a filter base (10). IMAGE
