Studies on the structure, life cycle and behaviour of Sardinella brasiliensis (Steindachner, 1979), in the region between 22º and 28ºS, Brazil: 4. Growth: quantitative aspects

Abstract

The length and weight growth parameters from Sardinella brasiliensis were estimated along the Brazilian coast between 22ºS and 28ºS (RJ-SC)3 showing two distinct patterns: first for the specimens living on the Cananèia-Paranaguá lagunar regions (25º -26ºS; III) and second from those of the coastal area; in this one was identified a northern group of individuals (22º -23ºS; I) with higher growth than those inhabiting the rest of the area (23º - 25ºS; II and 26º -28ºS; IV). The results suggest that the species is not homogeneous in the area where explotation occurs, supporting previous hypothesis. The estimated values of the growth parameters were: ;
