Resumo(s)
Data are presented on the breeding behaviour of Oreochromis mossambicus under captive
conditions. Males tended to synchronize their occupation of territories and breeding activities.
Different male mating tactics were observed, namely establishing a breeding territory, acting
as a floater, or behaving as a sneaker. The majority of spawnings observed involved dominant
males and were subjected to interference from other males. Males were found to court other
males that frequently responded to these attempts by adopting a female-like behaviour. Results
are discussed in terms of a probable time constraint in territoriality, which promotes male–male
competition and a low level of sex discrimination by territorial fish.
