Resumen del producto

The reproductive cycle of Holothuria (Selenkothuria) lubrica was monitored from November 2003 to November 2004. A total of 1438 specimens were weighted and measured and the gonad of 390 individuals were preserved for the reproduction analysis. The mean length and weight were 9.69 ± 0.070 cm and 18.25 ± 0.271 g respectively. The result showed that the species grows allometrically (b=2.072) at the study site. Five gonadal stages were described according to cell types present in the gonad: undetermined, gametogenesis, maturity, spawning and spent. Gonad index was estimated monthly and compared to gonadal stages and sea-surface temperature in order to determine if there was a relationship between these parameters. This holothurian is dioecious and sex ratio was not different from 1:1. The reproduction showed an annual pattern with a single spawning period during summer. The gonad index showed the highest values during summer, coinciding with mature gonads and when the sea-surface temperature reached its maximum. The calculated weight at first maturity was 27.3 g.
