A 56‐day nutritional research was performed to examine the influence of alternative vegetal protein and lipid sources on performance of yellowfin seabream fry (Acanthopagrus latus) (0.5 ± 0.0 g). In this regard, five isoproteic (Ca. 500 g/kg) and isolipidic (Ca. 150 g/kg) diets were formulated in which fish meal (FM) and fish oil (FO) were simultaneously replaced with blends of plant proteins (PP, soybean meal and corn gluten) and vegetal oils (VO, canola and soybean oils) at 20% (SR20), 40% (SR40), 60% (SR40) and 80% (SR80) levels, respectively; meanwhile, a control diet (SR0) was formulated based on FM and FO. Growth and feed utilization were not influenced by experimental diets. The fatty acid profile of fillet drastically altered by dietary treatments. Fish fed with the SR60 and SR80 feeds had higher total protease, trypsin and α‐amylase activities than other treatments. The antioxidant enzyme activities and glutathione content in liver were enhanced in fish fed with the SR40, SR60 and SR80 diets. Skin mucosal immune parameters including total protein content, alkaline phosphatase and alternative complement pathway activities in the control group were relatively lower than the vegetal treatments. According to these results, it is recommended that 410 g/kg of FM and 45 g of FO/kg can be replaced with alternative vegetal sources in diet for A. latus fry.

膳食中同时用黄鳍鲷（Acanthopagrus latus）鱼苗中的植物蛋白和植物油混合物替代鱼粉和鱼油：生长，消化酶，抗氧化状态和皮肤粘膜免疫力

进行了一项为期56天的营养研究，以检查替代性植物蛋白和脂质来源对黄鳍鲷鱼苗（Acanthopagrus latus）性能的影响）（0.5±0.0克）。在这方面，配制了五种等蛋白（约500 g / kg）和等脂（约150 g / kg）日粮，其中鱼粉（FM）和鱼油（FO）同时被植物蛋白（PP）的混合物代替，豆粕和玉米面筋）和植物油（VO，菜籽油和大豆油）的含量分别为20％（SR20），40％（SR40），60％（SR40）和80％（SR80）；同时，以FM和FO为基础配制了对照饮食（SR0）。生长和饲料利用率不受实验饮食的影响。鱼片的脂肪酸特征通过饮食治疗而发生了巨大变化。用SR60和SR80饲料喂养的鱼的总蛋白酶，胰蛋白酶和α-淀粉酶活性高于其他处理方法。饲喂SR40，SR60和SR80日粮的鱼的肝脏中抗氧化酶活性和谷胱甘肽含量增加。对照组的皮肤黏膜免疫参数包括总蛋白含量，碱性磷酸酶和替代补体途径活性均低于植物治疗。根据这些结果，建议在饮食中以替代的植物来源代替410 g / kg FM和45 g FO / kg。la炒。
