Resumo: | The reproductive biology of the introduced pumpkinseed sunfish Lepomis gibbosus (Linnaeus, 1758) in the Custódio's Dam, rio Doce high basin, state of Minas Gerais, Brazil was studied from February/2001 to March/2002 and compared with introduced and native populations. Reproduction occurred almost along the entire period of study with a high frequency of fishes in the advanced ripening/mature and spawned/spent stages. The microscopic analyses indicated that the pumpkinseed sunfish presents multiple spawning. The egg diameter of the Brazilian population is similar to the Spanish, Greek and American ones. The standard length at maturity and the gonadosomatic index of the introduced populations are smaller when compared with native ones. The spawning season of the Brazilian population was the longest among all comparisons made in the present work. |
