Growing Channel Catfish, Ictalurus Punctatus (Rafinesque), in Raceways

Techniques were investigated for growing channel catfish, lctalurus punctatus (Rafinesque), from fingerlings to harvestable size fish during the summer months in a recirculation, flowing water fish culture system in South Georgia. When stocked at a density of 2,000 fingerlings per 100 ft raceway unit, mean production was more than 2,400 Ib per unit with a feed conversion ratio of 1.28 to 1. Survival of the fish was 98.1 %. Successful culture of 2,400 fish in one unit indicated that the carrying capacity of the raceways used in this study was greater than 2,000 fish. There was a gradual...
