| 中文摘要: |
| 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，IIIand V，respectively. The results suggested that the patten B could keep the rapid growth of O. niloticus and maintain the better water quality. |
