摘要
对杂交鳢和乌鳢进行池塘养殖对比试验。前者投喂人工饲料,后者投喂冰鲜鱼,结合水质调控和病害防治等技术,杂交鳢成活率80.9%,乌鳢53.9%;杂交鳢平均单产为5.2 kg/m2,饵料系数1.367;乌鳢1.8 kg/m2,饵料系数4.29。整个养殖过程杂交鳢塘换水2次,乌鳢塘换水6次。
Northern snakehead （Channa argus） and its hybrid were stocked into a pond and fed formulated feed or frozen fish separately to evaluate the effect of different diets on growth performance and survival. During the experiment survival of 80. 9%, yield of 5.2 kg/m^2 and feed conversion ratio of 1. 367 were found in the hybrid culture pond in which the water was exchanged twice during the experiment while survival of 53.9 %, yield of 1.8 kg/m^2 and feed conversion ratio of 4.29 were observed in the northern snakehead pond in which the water was exchanged 6 times.
