Three
strains of Heterobranchus longifilis
were ob­tained from different ecological zones in Nigeria namely Nassarawa
(NS); Kainji (KK) and Ajase Ipo, (SW). 
Six intra specific progenies were obtained from the cross of the three
strains from the ecological zones, hatchability was highest (94.2%) in KK x KK
(Kainji strains); while the intra specific cross between KK x NS had the
highest (80.0%) hatchability. Gen­eral observation of the study point to the
fact that intra specific crosses involving SW and NS male have bet­ter survival
rates.
