Abstract
The feeding strategy of Characidium lanei and C. pterostictum was studied in the "Cabral" stream, a coastal stream of the Atlantic Forest, in southern Brazil. The samples were taken using electric fishing between March/95 and February/96. We studied about 15 stomach contents for each species in each season of the year. The stomach contents of the studied species were composed of 39 different food items, 28 in C. lanei and 24 in C. pterostictum. Chironomidae larvae and Ephemeroptera nymph were the most important items for C. lanei, except in the summer when Acarina and not identified Arthropoda were the most important items. Chironomidae and Simulidae larvae were the most important items in C. pterostictum. These results indicated an insectivorous habits and opportunist feeding strategy to C. lanei and C. pterostictum with several items rare or not very frequent.
