Estudos sobre estrutura, ciclo de vida e comportamento de Sardinella brasiliensis (Steindachner, 1879) na área entre 22ºS e 28ºS, Brasil: 4. Crescimento: aspectos quantitativos

Abstract: Foram estimados os parâmetros de crescimento em comprimento e peso para Sardinella brasiliensisda costa sudeste do Brasil (22ºS-28ºS), evidenciando-se dois padrões de crescimento distintos: um, para os exemplares que ocupam as regiões estuarino-lagunares de Cananeia e Paranaguá (25º-26ºS; III) e outro, para aqueles que ocupam as regiões costeiras da plataforma. Nestas regiões foi identificado um grupo no extremo norte da região (22º- 23ºS; I) com crescimento mais intenso que o verificado para o resto da área (… Show more

“…Being a short-lived fish, the growth rate of Brazilian sardinella is high and it is supposed to have an important bearing upon variations in the species' asymptotic length. Therefore, age and growth have been its most studied aspects in population dynamics, but the variety of methods used (length frequency distribution, age annuli in otoliths and scales, the Compleat ELEFAN, modal progression analysis and FISAT package) have yielded accordingly a wide array of estimates of K (0.31.yr -1 to 0.87. yr. -1 ), L oo (230 mm to 335 mm), and t o (-0.15 to -2.00 yr. (Richardson et al, 1960;Santos & Frantzen 1965;Rijavec et al, 1977;Matsuura, 1977 and1983;Vazzoler et al, 1987;Cergole & Valentini, 1994;Cergole, 1995;Cergole et al, 1999).…”
