RESUMO -Com o objetivo de quantificar a contribuição que quatro espécies, Cassia leiandra Benth., Crescentia amazonica Ducke, Macrolobium acaciifolium (Benth.) Benth. e Vitex cymosa Bert. ex Spreng., oferecem através de seus frutos à alimentação dos peixes, foram marcados, aleatoriamente, dez indivíduos adultos destas quatro espécies da floresta de várzea na ilha da Marchantaria -Amazônia Central. O período de maior produção de frutos dá-se no período do alto nível das águas, entre janeiro e maio. A espécie Cassia leiandra apresentou a maior produção com 1.836 kg/ha e amplo consumo pela população local. Os principais peixes consumidores de frutos são tambaqui (Colossoma macropomum), matrinxã (Brycon cephalus), pirapitinga (Piaractus brachypomus), pirarara, (Phractocephalus hemioliopterus), bacu (Lithodoras dors (Triportheus elongatus). As espécies de plantas estudadas apresentam potencial de aproveitamento como fonte de alimento para peixes.

Benth. and Vitex cymosa Bert. ex Spreng., as food resource for fishes, ten adult individuals of each species were labeled on Marchantaria Island. The peak of fruit offer occurred during the high water season, between the months of January and May. C. leiandra showed the biggest fruit monkeys and local people. The principal fruit consuming fishes were, tambaqui (Colossoma macropomum), matrinxã (Brycon cephalus), pirapitinga (Piaractus brachypomus), pirarara, (Phractocephalus hemioliopterus), bacu (Lithodoras dorsalis), pacu (Myiossoma sp., Myleus sp., Metynnis sp., Mylesinus sp.) and sardinha (Triportheus elongatus). The tree species show
