Intraspecific Hybridization Of Normal Pigmented And Albino Clarias Gariepinus From Yola And Katsina under Hatchery Condition

The study examined the reproductive indices of albino and normal pigmented Clarias gariepinus fish from Katsina (KT) Yola (YY), carried out under hatchery condition. experiment compared fecundity, testes, milt volume, percentage fertilization hatchability (AA) (NN) (YY). Normal C. had highest number eggs (229,240), followed by YY (127,250) least was recorded in Albino (124,750). weights lengths left right lobes as well volumes were quantified . However, KT weight length testis (18g 5.7cm respectively) while AA weight, volume (30g, 11cm 8.4ml respectively). testes observed YY. Meanwhile, 4.0ml 4.7ml, respectively. × (98.7% 98.5% among purebred, (98.4% 97.3% reciprocal hybrids. genetic crosses showed significant differences (p<0.05). results deduced essentiality hybridization. Furthermore, crossing broodstocks different regions have showcased contingency acquiring seed improved potentials hybrids aspects fertilization, rate, quality faster growth.
