Abstract:	Reproductive problems were encountered in attempting to produce the second generation of a four-way cross of tilapia from interspecific F1 hybrids. The cross (Oreochromis mossambicus x O. aureus) x (Sarotherodon galilaeus x O. niloticus) successfully bred for one generation, how- ever, not even a single batch of progeny was obtained in the subsequent generation. It was con- cluded that the complex genetic structure of this cross caused the fertility problem. Any similar breeding programs that are based on multi-species crosses should take into consideration that reproductive problems may occur.
