A desirable goal of the aquaculture sector is to replace most of fish meal and fish oil with more sustainable, cost-effective, and environmental friendly ingredients ensuring fish health and welfare standards. Due to minimal environmental impact, compared with most conventional feed commodities, insects deserve a growing attention as candidate ingredients for aquafeeds. The present study investigated, for the first time, the possible application of a 100% insect diet in zebrafish larval rearing. Through a multidisciplinary approach, the major biological responses of fish to the new diets were assessed. Results of biometry, fatty acid composition, expression of genes involved in fish growth, stress response, lipid metabolism, chitinolytic activity, gut inflammation, and liver macromolecular composition suggested a possible application of insect larvae for zebrafish larval rearing. However, further studies are necessary to better understand the use of this insect species in the rearing of fish.
水产养殖部门的一个理想目标是用更可持续、更具成本效益且环境友好的成分替代大部分鱼粉和鱼油，同时确保鱼类健康和福利标准。与大多数传统饲料原料相比，由于对环境影响极小，昆虫作为水产饲料的候选成分正受到越来越多的关注。本研究首次调查了100%昆虫饲料在斑马鱼幼鱼饲养中的可能应用。通过多学科方法，评估了鱼类对新饲料的主要生物学反应。生物测量、脂肪酸组成、参与鱼类生长、应激反应、脂质代谢、几丁质分解活性、肠道炎症和肝脏大分子组成的基因表达结果表明，昆虫幼虫可能适用于斑马鱼幼鱼饲养。然而，需要进一步研究以更好地了解这种昆虫物种在鱼类饲养中的用途。
