为了示范斑点叉尾(鱼回)从鱼种至成鱼阶段生长性能,本试验在江西省吉安市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进行了养殖试验。试验在3口2.0亩的鱼池中进行,每亩放养斑点叉尾(鱼回)600尾和白鲢100尾。经187天饲养,斑点叉尾(鱼回)从52克/尾长至平均710克/尾。斑点叉尾(鱼回)和白鲢的平均毛产量分别为415千克/亩和72千克/亩,它们的平均成活率分别为97.6%和100%。斑点叉尾(鱼回)对该豆粕型全植物性蛋白饲料的平均饲料系数为1.31:1。养殖试验的平均净利润为人民币1154元/亩,平均投资回报率为41.2%。利用美国大豆协会的80:20池塘养殖技术和豆粕型饲料进行的本试验,展现了斑点叉尾(鱼回)生长快、主动摄食和饲料系数低等特点。
In order to demonstrate the growth performance of Channel Catfish (FISH) from fish species to adult fish, the experiment was conducted in Ji’an City, Jiangxi Province by using the American Soybean Association 80:20 pond culture model and soybean meal-based adult fish feed. The experiment was carried out in 3 fish ponds of 2.0 mu, with 600 catfish and 100 silver carp per mu. After 187 days feeding, Channel Catfish (fish back) from 52 g / tail length to an average of 710 g / tail. The average gross yields of channel catfish (fish back) and silver carp were 415 kg / acre and 72 kg / acre, respectively, with average survival rates of 97.6% and 100%, respectively. The average feed ration of the channel catfish (fish back) to this soybean-meal whole plant protein feed was 1.31: 1. The average net profit of the breeding experiment was RMB1,154 / mu with an average return on investment of 41.2%. This experiment using the ASA 80:20 pond culture technique and soy-based diets demonstrated fast growth of the channel catfish (FISH), active feeding and low feed efficiency.
