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/m~2,饵料系数1.367;乌鳢1.8 kg/m~2,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.
對雜交鱧和烏鱧進行池塘養殖對比試驗.前者投餵人工飼料,後者投餵冰鮮魚,結閤水質調控和病害防治等技術,雜交鱧成活率80.9%,烏鱧53.9%;雜交鱧平均單產為5.2 kg/m~2,餌料繫數1.367;烏鱧1.8 kg/m~2,餌料繫數4.29.整箇養殖過程雜交鱧塘換水2次,烏鱧塘換水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.
