abstract={Backcrossing of Albino hybrid and parents <i>Clarias gariepinus</i> was conducted in the fish hatchery of Department of Fisheries, Teaching and Research farm, Modibbo Adama University of Technology Yola, Adamawa State, Nigeria, to study the reproductive and growth performance with the aim of determining the best in fertilization, hatchability, percentage survival and growth performance. Two pairs of brooders ˇáNN + ˇâNAlb and ˇâNN + ˇáNAlb were crossed. The results from the genetic cross ˇáNAlb x ˇâNAlb showed low performance in fertilization (75%), hatchability (61%) and survival (55%) while the highest was recorded in cross between ˇáNN x ˇâNN (95%, 82%, and 85%) respectively. The backcrossed ˇáNAlb x ˇâ NN), and reciprocal backcrossed ˇáNN x ˇâNAlb offspring reflected relatively intermediate fertilization (89% and 79%), hatchability (80% and 73%) and survival. (75% and 70%). However highest growth performance was recorded in backcross offspring (ˇáNAlb x ˇâ NN) with final weight (57.100ˇŔ1.5099), Weight gain (56.530ˇŔ1.4430), Daily weight gain (1.009ˇŔ0.0258), Length gain (4.5567ˇŔ0.0173), Daily length gain (0.0814ˇŔ0.0003) SGR(%/day) (3.58) and K factor (1.3) respectively. While high survival was found in parental cross (ˇáNN x ˇâNN). It was concluded that crossing the albino hybrids gave low growth performance while backcrossing with the female parent gave good growth performance. It is therefore recommended that breeding albino should be between parents and offspring to obtain better growth performance.},
