【 摘 要 】

The cost which spent for feed is about 50 - 70% of total component production. The method to reduce tiger shrimp production cost is using milkfish offal waste utilization as an alternative for feed substitution. This study used laboratory experimental method using completely randomized design with four treatments and three replications for each treatment. Each treatment used different milkfish offal meal (%) and fish meal (%) ratio, they were: 0%:60% (A), 20%:40% (B), 40%:20% (C), and 60%:0% (D). Feed was given four times a day at 08.00, 13.00, 17.00, and 23.00 about 8% of the shrimp biomass weight. The material used was juvenile tiger shrimp with 0.75 - 1.29 g of average biomass weight. Tiger shrimp maintained at 30 individuals of stock density in a bucket of water with 30 L volume and 30 ppt salinity. The results showed that crumble-shaped artificial feed with a different substitution percentage of milkfish offal meal had high significant effect (P0.05) on survival rate (SR). The highest value of RGR was 4.90%/day in treatment B. The best PER and feed efficiency were 1.69 and 56.96% in treatment B. Survival rate of tiger shrimp ranged between 83.33 - 87.78%. The water quality was in decent condition for shrimp cultivation media. The conclusion is 20% milkfish offal meal substitution in the artificial feed provides the best growth and survival rate of shrimp.
