CRESCIMENTO DO PEIXE-CACHORRO, Oligosarcus jenynsii (GUNTHER, 1864) NA LAGOA CACONDE, RIO GRANDE DO SUL, BRASIL (TELEOSTEI, CHARACIDAE)

Abstract

O presente trabalho teve como objetivo estudar o crescimento de Oligosarcus jenynsii da Lagoa Caconde/RS. Através de coletas realizadas mensalmente de julho de 1992 a junho de 1993, foram capturados 491 machos e 517 fêmeas. Foi utilizada a expressão de von Bertalanffy (1938) para a obtenção da curva de crescimento em comprimento. A curva de crescimento em peso foi determinada pelo método dedutivo, através das expressões da curva de crescimento em comprimento e da relação peso x comprimento. A formação do primeiro anel etário ocorreu no segundo ano de vida, sendo que, posteriormente, o anel etário aparece em épocas diferentes para os sexos. Os valores de L∠e WâˆÂ, obtidos para machos e fêmeas, foram 203,9 mm e 75,73 g e 258,7 mm e 162,3 g, respectivamente
