RESUMO

The food habits, seasonal, spatial and temporal distributions and some aspects of the morphology were examined for eighteen species of fishes of the ribeirão do Tabajara, Limeira, São Paulo. The fishes of a stretch (approximately 100 m) of the ribeirão do Tabajara were collected bimonthly, between November 1979 and October 1980. In the community studied, eight species, representing 44,4% of the total species sampled, were present in the stream all of the year. This resident community was composed of: Paroligosarcus pintoi, Geophagus brasiliensis, Cichlasoma facetum, Astyanax bimaculatus, Hypostomus ancistroides, Curimata gilberti, Characidium cf. fasciatum and Hyphessobrycon anisitsi. The other species (55,6%) joined the resident community only at certain times, thus determining the seasonal changes in the species composition of this community. Some of these species, considered immigrants, were collected only in the wet season (Hoplias malabaricus, Gymnotus carapo. Holoshesthes heterodon. Tilapia rendalli and Synbranchus marmoratus). others only in the dry season (Astyanax eigenmanniorum, Astyanax scabripinnis and Bryconamericus sp.) and others both in the wet and dry season (Rhamdia cf. hilarii and Rhamdella minuta). For A. heterodon, S. marmoratus, A. eigenmanniorum and A. scabripinnis it is not possible to conclude that these species occurred in the ribeirão do Tabajara only at the wet season or at the dry season because few specimens (less than five of each species) were caught along the year...
