Abstract: |
Hybrid was produced through cross breeding between native Asian catfish (C. batrachus) male and African C. gariepinus. Heterosis could not be compared between Fl hybrids because of poor gametic viability ofthe cross between C. batrachusC¥ and C. gariepinus (). Hybrid was compared at different stages from larval to market size with its respective control sibs. The average performance traits (viz. fertility, hatching rate, growth and survival) of individuals derived from cross between C. gariepinus~ and C. batrachus c3 was significantly better than its one of the control sib (C. batraclms). Hybrid showed high rate (31.5%) of deformity and abnormality in larval stage before the start of exogenous feeding and deformity extend until maturity. Significant divergence in morph type resembling to both of their parents and corresponding growth was found in hybrid population. In this preliminary study, hybrid showed heterotic in growth performance trait which might have important implication for the aquaculture industry. |
