摘要:

以初质量为(6.32±0.20 g)的黑鲷(Acanthopagrus schlegelii)幼鱼为研究对象，开展为期8周的室内流水生长养殖试验，研究不同饲料碳水化合物水平(17%、21%、25%)对黑鲷幼鱼生长性能、饲料利用、体组成和血清生化指标的影响。结果显示，饲料碳水化合物水平为21%时，黑鲷幼鱼的增质量率最大；饲料碳水化合物水平对黑鲷幼鱼的形体指标、饲料效率以及体组成没有显著影响(P>0.05)；饲料碳水化合物水平为25%时，黑鲷幼鱼的干物质、蛋白质和碳水化合物表观消化率显著低于其他2组(P<0.05)；黑鲷幼鱼血清葡萄糖和甘油三脂的含量随着饲料碳水化合物水平的升高而增高(P<0.05)；饲料碳水化合物水平对黑鲷幼鱼血清谷草转氨酶和谷丙转氨酶的活性没有显著影响。说明黑鲷幼鱼饲料蛋白水平为41%、脂肪水平为14%时，饲料碳水化合物的最适水平为21%。
