摘要
设置A、B、C 3种投饲模式,研究其对于池塘养殖新吉富罗非鱼生长及水环境的影响,结果表明,养殖全程模式A、B、C罗非鱼的相对增重率分别为3045.08%、3117.94%和3077.97%,模式B相对增重率高于模式A和模式C,且养殖对象生长较均匀;不同投饲模式下的浮游植物种群结构,模式B为6门32属,其种群多样性较模式A和模式C丰富;3种投饲模式塘水质等级分别为IV、III、V类水。分析认为,模式B更有利于实现池塘养殖新吉富罗非鱼较快生长及保持较好水质。
The study was to evaluate the effects of different feeding pattens （ A, B, C ） on growth of Oreochromis niloticus and water environment in pond culture. The results showed that the weight gain ratio of patten A, B, C were 3045.08%, 3117.94% and 3077.97%, respectively. The weight gain ratio of patten B was higher than that of patten A and C and more uniformly. The Phytoplankton community structure of patten B was 6 phyla and 32 genera, and the plankton diversity was richer than that of other pattens. The environment status of patten A, B, C belonged to IV, III and V, respectively. The results suggested that the patten B could keep the rapid growth of O. niloticus and maintain the better water quality.
