Successful reciprocal hybridizations between Clarias gariepinus and Heterobranchus longifilis were performed during three experiments. The reciprocal hybrids were viable, their survival rates being similar to those found in the maternal species. Hybrid morphology was intermediate to that of the parents. No difference in external morphology was found between the reciprocal hybrids. Growth rate comparison under the same conditions and over a period of 307 days, revealed a considerably faster growth for H. longifilis x male C. gariepinus hybrids displayed an even faster growth than H. longifilis.
