Mangrove crab (Scylla serrata) is a type of crustacean that lives in mangrove forests and estuaries, a member of the portunidae tribe. Mangrove crabs have considerable economic potential at home or abroad and the demand is also quite high. Its availability can only be obtained by continuous capture in the wild, so people are worried about its population. One way to overcome this is by maintaining mangrove crab fattening apartment system. Determination of feed dosage is one of the cultivation processes that needs to be understood because it affects the growth rate, survival and production levels of mud crabs. Therefore, it is necessary to conduct research on the effect of feeding different doses of raw fish on the fattening and survival of mud crabs (Scylla serrata). The purpose of this study was to analyze the optimal feed weight and frequency of feeding on fattening and survival of mud crabs in the crab box. The method used in this research is experimental method with complete randomized design. This treatment was carried out with 4 treatments and 3 replications, namely P1: 4%, P2: 8%, P3: 12% and P4: 16%. The four treatments were repeated 3 times so that 12 experimental units were obtained. the value of water quality parameters obtained during the study is still considered optimal. The results of the research conducted can be concluded that the provision of different doses of raw fish feed in fattening mud crabs is significantly different from the results of absolute weight and Specific Growth Rate (SGR) but not significantly different from the results of Survival Rate (SR) and Feed Conversion Ratio (FCR). The best treatment is p3 with a dose of 16%. The conclusion of this study can be concluded that the provision of different doses of feed affects the absolute weight and specific weight growth rate (SGR) of mangrove crabs (Scylla serrata). The water quality obtained is still optimal for mangrove crab cultivation.
