ABSTRACT



The “Safir” trout feed (Aller Aqua) was offered to carp (Cyprinus carpio) fry of 21 + 5 g/ind. initial weight, stocked at a density of 300 ind./m3 in cages placed in cooling water. Identical rations (5 – 4.0% metabolic weight) were offered for 6, 12, and 18 h per day. The data obtained showed the best results (as indicated by SGR and FCR) of culturing carp of up to about 75 g individual weight were obtained when the feeding took 18 h, 12 – 18 h being the best duration of feeding for the carp weighing 75 – 130 g. No effect of duration of feeding was observed in the carp weighing more than 130 g.

Key words: carp, cooling water, feeding time, metabolic daily ration..
