Yellow mealworm () larvae are a potential alternative animal protein source for sustainable aquaculture. However, reports on the successful complete substitution of fish meal with yellow mealworm larvae in an aquaculture diet have been limited. In this study, we conducted a feeding trial with red seabream () being fed diets with partial or complete replacement of fish meal with yellow mealworm larvae defatted with a hexane⁻ethanol solution. Feed intake in red seabream increased in accordance with yellow mealworm larvae inclusion, and diets including 65% defatted mealworm larvae (complete replacement of fish meal) showed significant growth promotion. The addition of the oil fraction from mealworm larvae to diets resulted in growth reduction, despite meeting the nutritional requirements of red seabream. Moreover, the survival rate of red seabreams fed diets with partial replacement of fish meal with mealworm larvae was significantly higher in a challenge test with pathogenic bacteria. The present study demonstrated that yellow mealworm larvae are not merely an alternative animal protein, but have potential as functional feed ingredients for aquaculture production.
黄粉虫（）幼虫是可持续水产养殖中一种潜在的替代动物蛋白来源。然而，关于在水产养殖饲料中用黄粉虫幼虫完全替代鱼粉取得成功的报道有限。在本研究中，我们用用己烷⁻乙醇溶液脱脂的黄粉虫幼虫部分或完全替代鱼粉的饲料对真鲷（）进行了饲养试验。真鲷的采食量随着黄粉虫幼虫添加量的增加而增加，包含65%脱脂黄粉虫幼虫（完全替代鱼粉）的饲料显示出显著的生长促进作用。尽管满足了真鲷的营养需求，但向饲料中添加黄粉虫幼虫的油分导致生长减缓。此外，在用致病性细菌进行的攻毒试验中，用黄粉虫幼虫部分替代鱼粉的饲料喂养的真鲷存活率显著更高。本研究表明，黄粉虫幼虫不仅是一种替代动物蛋白，而且有潜力作为水产养殖生产的功能性饲料成分。
