The establishment of protein and lipid requirements for growth of penaeid species is essential in maximizing productivity but information on the effects of these nutrients on gonad maturation is still lacking. Indian white prawn, Penaeus indicus (H. Milne Edwards) broodstock, were fed formulated maturation diets containing varying levels of dietary protein (35, 45 and 55%) and lipid (6, 12 and 18%) combinations following a 3×3 factorial design. Control group was fed with fresh mussel, squid and polychaete. Results indicate that treatment groups receiving diets of 45/18 and 55/12 protein/lipid combinations and the control exhibited higher maturation rates than the other treatments (p = 1.9 × 10⁻⁴). Shrimp broodstocks fed diets containing the lowest protein or lipid levels exhibited poor gonad maturation. Hepatopancreas damage and gonadal atresia were apparent in treatments with high dietary lipid based on histological and biochemical analyses. The diet with 55/12 protein/lipid combination is therefore best recommended for P. indicus gonad maturation. This study demonstrated that a well‐formulated diet that satisfies the protein and lipid requirements can support successful gonadal maturation comparable with feeding the broodstocks fresh maturation diets.

日粮蛋白质和脂质对印度白虾对虾亲虾成熟的交互影响

确定对虾物种生长所需的蛋白质和脂质对最大限度地提高生产力至关重要，但仍缺乏有关这些营养物对性腺成熟的影响的信息。在3×3因子分解后，向印度白虾Penaeus indicus（H. Milne Edwards）亲虾饲喂配方成熟的日粮，其中含有不同水平的饮食蛋白（35、45和55％）和脂质（6、12和18％）设计。对照组饲喂新鲜的贻贝，鱿鱼和多毛鱼。结果表明，接受45/18和55/12蛋白/脂质组合饮食的对照组和对照组的成熟率均高于其他治疗组（p  = 1.9×10 ^-4）。饲喂蛋白质或脂质含量最低的虾亲虾，其性腺成熟性较差。根据组织学和生化分析，在高饮食脂的治疗中，肝胰腺损害和性腺性闭锁很明显。因此，最好的建议与55/12蛋白质/脂质结合饮食P。 印度性腺成熟。这项研究表明，满足蛋白质和脂质需求的结构合理的饮食可以支持成功的性腺成熟，这与饲喂亲鱼新鲜的成熟饮食相当。
