Feeding management on the growth and survival rate of mud crab (Scylla serrata)

This study aimed to assess the growth and survival of mud crab (Scylla serrata) cultured in a brackish water fed with supplemental feeds. The experiment was laid out in a two-factor experiment, sex of mud crab and the kind of feeds. This is arranged in a Randomized Complete Block Design (RCBD). There were three replications with two samples per treatment. The first factor was the supplemental feeds and the second one was the sexes. Factor A comprised supplemental feeds such as trash fish, bread meal and grated coconut and Factor B was on the sexes, male and female. Majority of the male mud crabs supplemented with trash fish and those females fed with grated coconut survived on the second week. Of the three supplemental feeds used, male mud crabs gained the highest growth on bread meal while female mud crabs performed better in grated coconut. There is sufficient evidence to reject the null hypothesis since there is a significant difference on the performance of mud crabs between the use of supplemental feeds and sexes on their weight and length.
