Abstract:

Boddart's goggle-eyed goby (Boleopthalmus boddarti) is often found in mudflats of estuary and coastal areas, has abi-lity to walk on land and spawn inside the mud pits of hiding hole. The aim of this research was to study the fecundity and reproductive potential of mudskipper. Sampling was conducted in Losari, Tanjung and Bulakamba sub districts of Brebes regency from February to March 2012. Fish were caught using trap nets of 100 units for each station, then was repeated three times every two weeks. All fish samples were collected and preserved in 10% formaldehyde, then trans-ported to the laboratory for measurement of length, weight, gonad weight, and counting the number and diameter of eggs. The results showed that the smallest size of brood stock was 15.0 cm in length and 30 g in weight. The ratio of male and female showed a balance of 1:1. Fish condition factor tended to decrease when the levels of gonadal maturity increase. The gonad maturity index of the spawned brood stock ranged from 0.8 to 7.9%. The fecundity for each female brood stock ranged from 4,874 to 28,028 eggs with a mean of 14,520 eggs. Relative fecundity ranged from 108 to 577 with a mean of 303 eggs/g body weight. Gonad of mature female consisted of one size group, and egg diameter ranged from 0.38 to 0.55 mm with a mean of 0.47 mm. Keywords: Boleopthalmus boddarti, fecundity, reproduction, egg.
