Resumo - Estudos foram <strong>de</strong>senvolvidos visando conhecer a composição do zooplâncton e seu papel<br />

como indicador da qualida<strong>de</strong> ambiental no sistema estuarino <strong>de</strong> Barra <strong>de</strong> Jangada. As<br />

amostras foram coletadas com re<strong>de</strong>s com 300 µm <strong>de</strong> abertura <strong>de</strong> malha, em arrastos<br />

horizontais sub-superficiais. Foram i<strong>de</strong>ntificados 29 taxa, <strong>de</strong>stacando-se Copepoda com<br />

as espécies Pseudodiaptomus acutus e P. marshi, as quais são indicadoras <strong>de</strong> sistemas<br />

eutrofizados, evi<strong>de</strong>nciando forte poluição orgânica neste ecossistema.<br />

Abstract - Sdudies were carried out to assess the zooplankton composition and its role as<br />

environmental quality indicator of the Barra das Jangada estuarine system. Sampling<br />

were ma<strong>de</strong> with a plankton net 300 µm mesh size horizontaly hauled at sub-surface. It<br />

were i<strong>de</strong>ntified 29 taxa, dominating Copepoda wih most abundant species<br />

Pseudodiaptomus acutus and P. marshi, which are euthrophication indicators showing<br />

the high organic pollution of this ecosystem.<br />
