- Abstract
The increase of the export demand of crabs (Scylla serrata), among others caused by the good taste and have a very high nutrition value, but most of the crab still collected by fishing of natural stock. Therefore, technology of crabs culture should be enhanced. This research was aiming to understand the influence of sexual, feeding regime, environmental factors to the growth rate. This research was conducted experimentally using the randomized block design with factorial pattern 2x2x3. The growth rate and weight gain were measured weekly. The results show that male crab reared in individual aquarium fed by mixed fish revealed the quickest ultimate growth rate i.e. 1.07 g.day-1, as well as achieving the highest weight gain i.e. 84.73%. While in mass rearing method, female crab fed by mixed fish achieved the highest ultimate growth rate ie. 0.8 g.day-1, and the highest weight gain achieved in male crab fed by mixed fish i.e. 52.03%. Anova test reveal that sexual factor and it's interaction was significantly different. The research conclude that the growth of the crab fed by mixed fish was higher than those fed by bivalve meat or combination of mixed fish with bivalve meat; male crab reared individually and fed with mixed fish revealed has higher growth rate then the female crab; and the growth rate of female crab reared in a mass and fed by mixed fish revealed the highest growth rate.
