“…This is mainly because the hybrid generally performs better than either parent species for several important production traits including survival, growth, disease resistance, and carcass yield (Giudice 1966;Yant et al 1976;Dunham et al 1990;Wolters et al 1996;Bosworth et al 2003Bosworth et al , 2004. Much of the research conducted so far on hybrid catfish has been on how to improve spawning success and compare their production traits with channel catfish.…”

The present study examined the effects of various daily feeding rates and feeding every other day on the growth, net yield, feed conversion ratio, and size distribution of hybrid catfish (female channel catfish Ictalurus punctatus × male blue catfish I. furcatus) in production ponds. Hybrid catfish fingerlings (average size, 45 g) were stocked into 0.04‐ha ponds at a density of 14,826 fish/ha. Initially, all fish were fed to apparent satiation until feed consumption reached predetermined levels. Thereafter, the daily feeding rates for fish in the restricted feeding group were no more than 112, 135, or 168 kg·ha−1·d−1. Fish in the every‐other‐day feeding group were fed to apparent satiation daily until they reached about 0.23 kg and every other day to satiation thereafter. The results from the present study show that feeding every other day significantly reduces the weight gain and net yield of hybrid catfish but improves the feed conversion ratio. Partial budget analysis indicates that feeding hybrid catfish every other day is not economical at recent feed and fish prices. There were no significant differences in net yield, weight gain, and percentage of market‐size fish among fish fed daily at various rates. Fish fed daily at no more than 112 and 135 kg/ha had significantly lower feed conversion ratios than fish fed daily to satiation. Simple regression analysis indicates that the weight gain, net yield, feed conversion ratio, and percentage of market‐size fish increased linearly as the total amount of feed fed increased in fish fed daily. The results also show that the feed restriction used in the present study does not affect the size distribution of hybrid catfish.

“…There were no significant differences between the growth curves of hybrid fishes and pure A. butcheri . Previous studies that have compared growth between hybrids and their pure parental strains have mainly shown some divergence between the two strains, with hybrids often growing faster than parental species due possibly to heterotic effects (Hubbs, 1955; Giudice, 1966; Green & Rawles, 2010). In the few other cases where the growth of hybrid fishes has been similar to that of at least one parental species, the absence of any heterotic effect under normal environmental conditions has been suggested (Cowx, 1983; Legendre et al , 1992).…”

This study examined the spatio-temporal reproductive patterns, population structure, maturity and growth of Acanthopagrus hybrid complexes, which comprise mainly black bream Acanthopagrus butcheri and the hybrids they form with yellowfin bream Acanthopagrus australis, in two Australian estuaries (Coila and Brou Lakes, NSW). There were no differences between pure A. butcheri and hybrids in terms of their population structure, growth and maturity, suggesting that these two breeds have similar life histories and may therefore be managed as single, naturally cohesive units. Sexual variation in size structure was only observed for the complex in Coila Lake. Although there was significant variation in age structure between estuaries, both complexes exhibited dominance of only a few year classes indicating episodic recruitment and high fishing mortality. Acanthopagrus eggs occurred in higher numbers within upstream creek habitats compared to lake habitats, thereby highlighting the need to protect these spawning habitats. Although maturity in the complexes was not influenced by gender or estuary, differences in growth were detected between the genders and estuaries.
