Abstract
Abstract Blue catfish Ictalurus furcatus were significantly easier to harvest by seining than channel catfish I. punctatus female channel catfish × male blue catfish F1 and F2 hybrids, channel catfish backcrosses, and blue catfish backcrosses (P < 0.05). The F1 hybrid was significantly easier to catch than channel catfish (P < 0.05). The F3 hybrid was significantly easier to catch than the F2 hybrid, channel catfish, and channel catfish backcrosses (P < 0.05). Individual epistatic recombination loss had a positive effect on percent fish caught in the first seine haul. Channel catfish additive genetic effects had a negative effect on ease of capture by seining. The more channel catfish genes present, the harder the fish was to catch.
