Mud crab is one of the fishery commodity which potential to be cultured because it has high economic value. Mud crab has nutrients content such as protein 62,72%, lipid 0,83%, ash 7,5% and water content 9,9%. Trash fish is fresh feed which commonly used as main feed for the growth of mud crab juvenile of 5,3to 13,8%, however Kuniran fish has omega-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content which is necessary for optimum growth of mud crab.The study method was implemented as the experimental method use Completely Randomized Design (CRD) which consists of five treatments and four replications. The quantity of Crude Fish Oil which is added in trash fish feed on this study are: Treatment A (0%), B (2%), C (4%), D (6%) dan E (8%). The observed parameters are growth of mud crab and feed conversion ratio value. Data analysis use Variant Analysis (ANAVA) and continued with Duncan's Multiple Range Test to determine differences between treatments. The results shows that addition of Crude Fish Oil in trash feed fish for 32 days of rearing gives significantly different effect (P 0,05). High length and width growth of carapace were obtained on D and E treatment. The water quality of mud crab during 32 days of rearing is the temperature range of 28-29°C, pH range of 7,5-9,0, salinity range of 15-21ppt, dissolve oxygen range of 4 mg/l and ammonium range of 0,09-0,27 mg/l.
