| Abstract: |
| 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. |
