Abstract

By analysis of seasonal variations of relative frequency of repletion stages and average index of stomach repletion, plus the analysis of the condition factor, the seasons of more intensive predactory activity (Summer) and fat condition (Autumn) were determined in S. spilopleura from Bariri Reservoir. It was also determined how body weight varies with total length, according to Santos (1978), resulting:

W = 0.00602 L3.4711

Where:

W = total weight of body (g)

L = total length of the fish (cm)
