Abstract: Interspecific hybridization between Clarias macrocephalus (CM) and Clarias gariepinus (CG) has been conducted to produce hybrid with specific desirable traits. To evaluate its potential application in aquaculture, fertility and performance of desirable traits (e.g. growth, external morphology, flesh quality, disease resistance) were examined on reciprocal Fi and backcross hybrids. Reciprocal hybrids were partially fertile with various abnormalities in gonad development that resulted in low gamete production. Abnormalities observed in gonad development of all hybrid genotypes included a single ovary or testis, tumor-like and adipose-like tissues in ovaries, ovotestis, and retarded gonad. Reciprocal hybrid males had problems with spermatogenesis that was likely due to genetic incompatibility since treatment with hormones did not improve spermatogenesis.
