Foi examinado o conteúdo estomacal de seis espécies de peixes da lagoa do Jiqui (5º55’00’’S e 35º11’28”W ), Parnamirim, Rio Grande do Norte, coletados mensalmente durante o período de março de 1994 a fevereiro de 1995. A importância relativa dos componentes da dieta foi medida pela freqüência de ocorrência, método dos pontos e pelo uso do índice alimentar proposto por Kawakami e Vazzoler (1980). Verificou-se que as espécies se alimentam principalmente de peixes, insetos, crustáceos, moluscos e matéria orgânica, apresentando um hábito alimentar pelágico.<br>This paper presents the study of the stomach content of six fish species of Jiqui lagoon (5º55’00’’S and 35º11’28”W ), located in the municipality of Parnamirim, Rio Grande do Norte, Brasil. A total of 261 specimens, collected monthly between March 1994 and February 1995 were examined. The relative importance of the diet components was measured through the frequency of occurrence, method of the dots and the use of the feeding index proposed by Kawakami and Vazzoler (1980). The specimens were found to feed mainly on fish, insects, crustaceans, mollusks, and organic matter. This suggests that the trophic habit of those specimens takes place in the pelagic area of the lagoon.
