关于水库宜鱼水面的计算方法,各地极不统一,有的按水库溢洪时淹没线所涉及的面积(即最大水面),有的按死库容的水面(即最小水面)。据我们调查,这两种方法都不能反映水库宜鱼面积的现实,因为水库水位随着气候、雨量以及灌溉、发电用水而发生很大的变化。若按最大水面计算投放鱼种,随着水位的下降,放养密度相对增大,放养的鱼类不能按时达到商品鱼规格、延长 The method for calculating the surface area of ​​reservoirs should be very uneven. Some areas cover the area covered by flooding lines when the reservoir overflows (ie, the maximum surface water level), and some are dead (that is, the minimum surface water level). According to our investigation, neither of these methods can reflect the reality of reservoirs should fish area, because the reservoir water level with the climate, rainfall and irrigation, power generation water and great changes. If according to the maximum water surface put the fish species, with the decline of the water level, stocking density is relatively increased, the stocking of fish can not reach the commodity fish specifications, extend
