GROWTH PERFORMANCE OF MUD CRAB, Scylla serrata (Forsskal, 1775) USING DIFFERENT INCLUSION LEVELS OF CRAB SHELL MEAL

This study was conducted to investigate the effects of the different inclusion levels of Portunus  pelagicus crab shell meal on growth and survival performance of mud crab, Scylla serrata. There were three (3) dietary treatments used, namely: 0% as negative control (T1), 10% (T2) and 20% (T3) crab shell meal  fed on mud crab for a culture period of 30 days using a Completely Randomized Design (CRD). Results revealed that there were no significant differences among treatment diets (p>0.05). Results of the feeding trial also showed that weight gain, specific growth rate (SGR) and survival rate obtained higher in T3 with 19.4, 0.18  and 83.33 but obtained lowest initial weight (IW) and feed intake (FI) with 129.2 and 358.1, respectively (p>0.05). Results also revealed that 20% crab shell meal  could be a preferable inclusion level that enhance better growth, survival and feed conversion efficiency of mud crab.
