Abstract

The aim of this study was to determined reproductive biology (sex ratio, gonad maturity stages, fecundity and size of first maturity) of the sentinel crab (Podophthalmus vigil) in the west Tiworo Strait.Samples were obtained from the bycatch of the crab fishermens using trap.Each sample obtained was indetified thesex,carapace width and body weight were measured. Sex ratio was analyzed using Chi-square test (p<0,05). Gonad maturity levels was observed from changes in gonad morphology and color. The crab fecundity was calculated using the gravimetric method. The crab fecundity was calculated using the gravimetric method. The results of the study obtained a sex ratio of 1: 4.09; showed an imbalance between males and females. The gonad development of male P. vigil was dominated immature gonads, while that of females was dominated by mature gonads. Fecundity of P. vigil ranged from 415,644-3,466,290 eggs, and the size 50% at the first maturity of female crab was 92.29 mm.
