Effects of Stocking Density on Production Traits of Channel Catfish×Blue Catfish Hybrids
Channel Catfish Ictalurus punctatus × Blue Catfish I. furcatus hybrid fingerlings (mean weight, 47 g) were stocked in 0.4‐ha ponds at densities of 7,425, 12,375, 17,325, 22,275, and 27,225 fish/ha in three replicate earthen ponds for each density. Fish were fed a 28% protein diet to apparent satiati...

| Zusammenfassung: | Channel Catfish Ictalurus punctatus × Blue Catfish I. furcatus hybrid fingerlings (mean weight, 47 g) were stocked in 0.4‐ha ponds at densities of 7,425, 12,375, 17,325, 22,275, and 27,225 fish/ha in three replicate earthen ponds for each density. Fish were fed a 28% protein diet to apparent satiation once daily. Ponds were equipped with electric paddlewheel aerators (12.5 hp/ha) that were turned on when dissolved oxygen (DO) levels reached |
