Abstract

The aim of this study was to investigate the influence of gonadal and nutritional index on the reproductive behavior of Scomberomorus brasiliensis Collette, Russo and Zavala-Camin, 1978 (Perciformes, Scombridae) of the western coast of Maranhão, from June 2001 to July 2002. There was a significant dominance of females when considering the total experimental period. The length/weight relationship did not show a significant difference between the sexes in reference to the alometry coefficient. Analyses of the maturation curve, based on the monthly mean values variation of the gonadosomatic and hepatosomatic relation, and the condition factor, suggest that the reproductive period occurs from March to June. It was observed that the losses of body and liver weight occurred during the gonodal maturation and reproductive processes. The variation analysis of the repletion index mean values showed that the fishes exhibited better feeding conditions before and after the reproductive season
