The aim of this study is to increase the survival rate and development of early larvae stage of mud crab which are generated from improving quality broodstock through different rearing treatment and feeding methods. The selected broodstocks which fed fresh fish 6% of wet body weight (BW) were reared in mangrove habitat. To obtain the mature ovaries of broodstocks, individual crabs were then treated with fresh food as much as 6% BW with different compositions as follows: 1) 3% fresh fish, 1.5% squid, and 1.5% shrimp; 2) 1.8% fresh fish, 3% squid, and 1.2% shrimp; and 3) 1.8% fresh fish, 1.2% squid, and 3% shrimp. Each treatment used 3 individual crabs as replication. Matured broodstock then incubated in aquarium untill produced early stage of zoea larvae (Z1-Z2). The results showed that there were positive correlation between egg qual...

Control of reproduction to increase seed production through feed improvement, is one of the challenges and strategies in the mud crab aquaculture. Due to lack of knowledge about broodstock nutrition lead to producing rate of seeds still relatively low. This study aimed to obtain information on the kind of feed that has specific nutrient and plays a role in increasing the success of spawning and zoea survival. Mud crab of Scylla serrata with initial weight of 500.7±103.4 g, preferably under developed gonads were maintained in a fiber tank measuring length of 2.48 m, width 1.26 m, and a height of 60 cm which is partition sealed into 30×40×60 cm3 to put one crab. Tank was equipped with sand as a substrate as high as 15 cm and seawater system with flow rate of 1 L per six minutes and 25 cm high water. Treatments were consisted of: 1. PI (fresh meat fish of Decapterus sp. with dose of 5%), 2....
