INTRASPECIFIC HYBRIDIZATION AND RECIPROCAL CROSS BETWEEN CULTURED AND WILD Clarias gariepinus; AND EVALUATION OF THEIR PROGENIES

Abstract

Studies of intraspecific hybridization and reciprocal cross between cultured and wild Clarias gariepinus and 

evaluation of their progenies was carried out, with aim of evaluating the progenies of the crosses hatchability, 

survival, growth etc. Pure strains of cultured and wild Clarias gariepinus broodstock were used. Incubation, 

hatching, and post hatching activities were monitored in 50 litres plastic bowls. Cultured Male Clarias 

gariepinus (CCG♂) x Wild Female Clarias gariepinus (WCG♀) were used as Treatment 1 with Replicate and 

Wild Male Clarias gariepinus (WCG♂) x Cultured Female Clarias gariepinus (CCG♀) as Treatment 2 with 

Replicates. The result showed that in all the two genetic crosses, (CCG♂) x Wild Female Clarias gariepinus

(WCG♀) had the highest fertilization rate (84.93%). Statistically, there was a significant difference (p
