Abstract

This study was undertaken with a sample of 221 specimens of Crenicichla lepidota, ranging between 4.0cm and 14.0cm of total length, collected monthly at the lagoa Redonda (4º51’54’’ and 68º58’18’’LS and 34º57’08’’ and 38º35’12’’WG) using nylon fishing nets and fish-hook, from April 1987 to March 1988. The diet components were analyzed by a method of points, by the frequency of occurrence of feeding items (Hynes, 1950) and by a feeding index suggested by Kawakami and Vazzoler (1980). The diet of Crenicichla lepidota mainly includes Insecta, Crustacea and Pisces. Qualitative and quantitative changes were not verified with regard to sex and during dry and flood seasons.
