Growth of fed aquaculture is dependent on finding sustainable and inexpensive ingredients that would satisfy the nutritional requirements of fish. The present work assessed restaurant post-consumer food waste as an ingredient in feeds for small (ca 6.5 g) rainbow trout, Oncorhynchus mykiss. Food waste from Lebanese-food restaurants was used to prepare seven iso-nitrogenous feeds (ca 42.5% protein, 18% lipid) by replacing soybean meal (SBM), soy oil, and whole wheat in a control diet. Seven diets containing 0, 5, 10, 15, 20, 25, and 30% food waste were made. Fish were stocked in triplicate 52-L tanks (15 fish per tank) and offered the feeds at 4% body weight daily for 8 weeks. Growth, hematology, and proximate chemical composition of the fish were assessed. Results show that food waste can be incorporated as 25% of the diet without affecting growth of O. mykiss. The best growth (ca 317% from initial stocking weight) was observed in fish offered feed with 20% food waste. Feed treatment did not significantly affect hematology, but significantly affected body composition. Total fish body protein proportion was greater in the treatment offered 30% food waste feed than in the control. There seems to be a potential for using food waste as an ingredient in trout feed, and this could mitigate the environmental consequences of disposal of food waste.

饲料水产养殖的增长取决于寻找能够满足鱼类营养需求的可持续且廉价的成分。本工作评估了餐馆消费后的食物浪费，作为小（约6.5克）虹鳟鱼Oncorhynchus mykiss饲料的成分。黎巴嫩食品餐馆的餐厨垃圾用于代替对照豆粕（SBM），豆油和全麦来制备7种同氮饲料（蛋白质约42.5％，脂质18％）。制作了包含0、5、10、15、20、25和30％食物浪费的7种饮食。将鱼放进一式三份的52公升水箱中（每箱15条鱼），并以每天4％的体重提供饲料，持续8周。评估鱼的生长，血液学和附近的化学成分。结果表明，食物垃圾可以占饮食的25％，而不会影响my.kisss的生长。在提供鱼饲料和20％食物浪费的鱼中观察到最佳生长（从初始放养重量开始约占317％）。饲料处理不会显着影响血液学，但会显着影响身体组成。在提供30％的食物垃圾饲料的处理中，鱼体内蛋白质的总比例比对照组高。似乎有可能将食物残渣用作鳟鱼饲料的成分，这可以减轻食物残渣处置对环境的影响。
