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).

This suggests that the trophic habit of those specimens takes place in the pelagic area of the lagoon.http://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/4417hábitos alimentaresespécies de peixeLagoa do Jiquiárea pelágica
