本试验在江苏常州通过利用美国大豆协会的80:20池塘养殖模式和豆粕型成鱼饲料对团头鲂从鱼种至成鱼阶段的生长性能进行了评价。试验在3口5亩的鱼池中进行,每亩放养团头鲂800尾和白鲢100尾。经188天饲养,团头鲂从50克/尾长至平均462克/尾。团头鲂和白鲢的平均毛产量分别为387千克/亩和113千克/亩,平均成活率分别为100%和95%。团头鲂对该豆粕型全植物性蛋白饲料的平均饲料转化系数为1.22:1。养殖试验的平均净利润为人民币705元/亩,平均投资回报率为34.5%。利用80:20池塘养殖技术和豆粕型饲料进行团头鲂养殖,表现了团头鲂生长快、主动摄食和饲料系数低等特点。
The experiment was conducted in Changzhou, Jiangsu Province by using the ASA 80:20 pond culture model and soybean meal-based fish feed on the growth performance of Bream mullet from fish to fish stage. The experiment was carried out in 3 fish ponds of 5 mu. There were 800 tuna and 100 silver carp per acre. After 188 days of breeding, bream 鲂 from 50 g / tail length to an average of 462 g / tail. The average gross yields of bream and silver carp were 387 kg / acre and 113 kg / acre, respectively, with an average survival rate of 100% and 95% respectively. The average feed conversion coefficient of bream was 1.22: 1 for this soybean-based whole plant protein feed. The average net profit of the breeding experiment was RMB 705 yuan / mu and the average return on investment was 34.5%. The use of 80:20 pond farming techniques and soybean meal feed for bream breeding, showing the fast growth of bream, feeding and feed characteristics of low.
