Information regarding the reproductive cycle of commercially exploited fish species is extremely important for their appropriate management. The reproductive size of Pinirampus pirinampu (Spix, 1829) was determined for a population studied in the Pantanal wetlands of western Brazil. Samples were taken in September, October, and December 1997, and in February and March 1998. Gonadal stages were macroscopically determined and a monthly gonadossomatic index (GSI) was used to determine the breeding… Expand
