微生态制剂在彭泽鲫池塘健康养殖中的应用效果研究

在同一水域选择6口池塘,其中3口池塘作试验塘,另3口作对照组。试验池塘中投放微生态饲料添加剂和水质改良剂,对照组中不投放。6口池塘采取相同的饲养管理方式,经9个月的饲养,结果得出:试验组的鱼摄食强度比对照组要大;试验池的溶氧条件始终优于对照组,透明度比对照池高;试验池中鱼的生长情况始终优于对照池,单产水平高于对照组,饲料系数低于对照组;试验池鱼的出肉率与肌肉营养成份与对照组相比差异不显著。

Application Effects of Micro-ecological Agent to Pond of Pengze Crucian

6 ponds were selected in the same water area,in which 3 ponds were test group,another 3 ponds were check group.6 ponds were in the same feed management,in test ponds micro-ecological agent and water quality amendment were applied.The results showed after raising crucian for 9 months,the feeding intensity of test group was better than that of check group;the dissolved oxygen and the transparency of test pool were better than those of check pool;the growth of the fish in test pool was better than that of check group;productive level was higher than check group,while the forage coefficient of test pool was lower than that of check group;the muscle nutrition composition and the meat rate of test pool had no remarkable difference with check group.
