摘　　要：为研究不同开口饵料对河川沙塘鳢的仔鱼生长和鱼体成分的影响,选择4种开口饵料,分别为经小球藻强化培育的轮虫、蛋黄、轮虫+小型枝角类和鱼苗专用开口配合饲料。通过15 d的投喂实验,选出最适口的开口饵料。实验表明,经过15 d的投喂以小球藻强化培育的轮虫作为开口饵料最为适合,其平均体长为8.759 mm,平均体重为0.050 3 g,成活率为94%,蛋白含量21.65%,脂肪含量1.57%。其次为轮虫+小型枝角类组,蛋黄和鱼苗配合饲料不适合作为开口饵料。To study the effects of different opening diets on Odontobutis potamophila larvae growth and body composition,four opening diets were selected and they were rotifers enhanced cultivated by Chlorella vulgaris;egg yolks,rotifers ＋ small cladocerans and larval dedicated opening diets. We selected the most palatable opening diets through 15 d of feeding experiments. Experiments show that rotifer enhanced and cultivated by Chlorella vulgaris was the most suitable opening diet,with an average body length of 8. 759 mm,average weight of 0. 050 3 g,the survival rate of 94%,the protein content of 21. 65% and the fat content of 1. 57%;followed by rotifers ＋ small cladocerans group and egg yolks group. Larval dedicated opening diets is not suitable as a weaning food.
