Resumo: The ichthyofauna of ribeirão Grande microbasin that runs through one of the few remaining fragments of Atlantic Forest (in Mantiqueira mountain range, Valley of Paraíba) was studied. Fish samples were obtained with an electric fishing powered by a maximum capacity generator of 155 V and 60-Hz alterning current, gill-nets and traps. In three collecting days, during July/2001, October/2001, January/2002 and April/2002, 2865 fishes were sampled. These fishes belonged to 12 families, 23 genera and 37 species. The species were more abundant between the piedmont and the plain of the Valley of Paraíba. The Characidium, Trichomycterus genera and the Imparfinis minutus species presented only one ovary or testis and no swim bladder. The ecological significance of morphological features in stream mountain fishes was used to predict the niche adaptation for those conditions, towards K-strategy

As amostras de peixes foram obtidas com um aparelho de pesca elétrica, ligado a um gerador com capacidade máxima de 1500 V e 60-Hz, com corrente alternada, redes de emalhar e covos. Em três dias de coleta em julho de 2001, outubro de 2001, janeiro de 2002 e abril de 2002, foram amostrados 2865 exemplares de peixes, pertencentes a 12 famílias, 23 gêneros e 37 espécies. As espécies foram mais abundantes entre o pediplano e a planície do Vale do Paraíba. Os gêneros Characidium, Trichomycterus e a espécie Imparfinis minutus apresentaram somente um ovário ou testículo e ausência de bexiga natatória. Essas evidências ecológicas de características morfológicas em peixes de riachos de montanha foram usadas para predizer a adaptação ao nicho para aquelas condições, em direção à estratégia KUniversidade Estadual De Maringá2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/165610.4025/actascibiolsci.v26i1.1656Acta Scientiarum.
