水库养殖品种结构的改革不同于池塘养殖品种结构的改革,它比池塘要复杂得多。第一,水库是个非常复杂的水生态系统,它的结构和功能比池塘复杂,鱼类的栖息环境和天然饵料基础表现出多样性。据此,我们在进行品种改革时,首先必须考虑充分利用这些自然资源,才能达到经济有效。第二,各地水库的自然环境条件差异 The structural reform of reservoir aquaculture species is different from the reform of the structure of pond aquaculture species and it is much more complex than that of ponds. First, the reservoir is a very complex aquatic ecosystem. Its structure and function are more complex than that of the pond. The habitat of the fish and the natural food base show diversity. Therefore, when we carry out variety reforms, we must first consider how to make full use of these natural resources in order to achieve economic efficiency. Second, the natural environment of different reservoirs varies
