三峡水库蓄水后,尽管水位、流速等水文条件发生了改变,但总体上并未对现有渔具作业造成明显影响,原有的渔具基本上可以继续使用;但并不排除某些江段对部分渔具的影响。蓄水初期,库区渔民捕捞产量减少只是暂时现象,经过一定时期后,渔民的捕捞产量比蓄水以前可能有所增加,可减少库区渔民的部分损失;但从鱼类种群结构来看,流水性鱼类减少,缓流性鱼类增加,由于前者的价格大大高于后者,这对库区渔民的经济收入可能会带来一定的影响。如果考虑因三峡水库蓄水导致库区渔民捕捞产量减少造成的损失给予一定的经济补偿,应对库区现有渔民数量、蓄水前后单船日捕捞产量、作业时间、渔获物中主要品种的比例和价格等指标进行核定。
Although the hydrological conditions such as water level and flow rate have changed after the Three Gorges Reservoir was charged, the existing fishing gear basically could not be obviously affected by the hydrological conditions. However, it is not excluded that some of the river sections Part of the impact of fishing gear. In the initial stage of water storage, the reduction of fishery production in the reservoir area is only a temporary phenomenon. After a certain period of time, the fishery’s fishing output may increase more than that before water storage, which may reduce some losses of fishermen in the reservoir area. However, The decrease of flowable fish and the increase of slow-flowed fish will probably affect the economic income of fishermen in the reservoir area because the price of the former is much higher than that of the latter. If we consider some economic compensation due to the loss caused by the reduction of catch of fishermen in the reservoir due to the impoundment of the Three Gorges Reservoir, it is necessary to consider the number of existing fishermen in the reservoir area, the daily fishing yield of single vessel before and after impounding, the operation time, the main species Ratio and price indicators for approval.
