Abstract

Effect of eutrophic water in the gill of the Nile tilapia (Oreochromis niloticus) from Aclimação park lagoon Key words: Oreochromis niloticus, gill, pollution, eutrophication, biomarkers Abstract Into the downtown place of the city of São Paulo situed the Aclimação Park that since 1939 had been suffering a lot of modifications about urbanity actions, there is a lagoon of 33.380 m² with eutrophic waters (rich in organic materials), provided with the local sewerage systems, nascent and pluvial waters. In Aclimação lagoon it had been described the presences of fish, the teleostei Tilapia (Oreochromis niloticus). This fish, have an economic interest, and is very easy to obtain heath fishes from commercial fish farms for comparisons with the lagoon fish. Therefore, in histological comparating the lagoons species with farm fish samples, it can be possible to evidence biomarkers and adaptive characteristics of these fishes to water eutrhophication. The objective o this present project is to analyze and to characterize possible effects of the water of the Aclimação Park lagoon in the gills of Nile Tilapia (Oreochromis niloticus) evidencing the action of the poluents. According to that, will be released specific histological stains, electron transmission microscopy and morphometry analysis of the samples from the lagoon and from commercial fish farm. (AU)
