| Abstract | The effect of dietary lipid on reproductive performance of pond-raised Penaeus monodon was compared using three practical diets. Diets were formulated to contain the same basal ingredients but supplemented with different sources of lipids: cod-liver oil for diet A; a 1:1 combination of cod-liver oil and soybean lecithin for diet B; and soybean lecithin for diet C. An all-natural diet consisting of squid, mussel, and marine annelids served as control. Four 12 m³ flow-through maturation tanks were each stocked with 50 broodstock at a sex ratio of 1.5 females: one male with the females ablated on one eyestalk. The reproductive performance, measured as the total number of spawn sizes, the egg quality (based on morphology), and the average hatching rate of eggs, of each dietary treatment was assessed. The overall response of the broodstock was best for diet A followed by diet c. Response to diet B was the poorest among the formulated diets but was better than the control. Most of the females fed the control diet resorbed their ovaries and failed to spawn; their survival rate was also the lowest. The results suggest that the lipid source in the broodstock diet affects reproduction and egg quality. Diet A proved to be a suitable diet that can support maturation and spawning of good quality eggs from pond-reared P. monodon broodstock. |
