Crescimento e mortalidade de Oligosarcus hepsetus (Cuvier, 1829) (Characiformes, Characidae) no Parque Estadual da Serra do Mar, Núcleo Santa Virgínia, São Paulo, Brasil
Abstract:Growth and mortality parameters were estimated for Oligosarcus hepsetus caught in the Serra do Mar State Park, Núcleo Santa Virginia. Monthly length frequencies distributions were analyzed with the ELEFAN method within the FISAT program, using the seasonal version of the Von Bertalanffy's growth curve. The instantaneous rate of natural mortality was calculated using the empirical formula proposed by Pauly. The estimated parameters were K = 0.72, L∞ = 23.3 cm, C = 0.3, Wp = 0.7 and M = 1.25. These parameters co… Show more
