在使用固定式过鱼建筑物时,由于电站前的鱼类集聚情况往往发生变化,因此能过坝的亲鱼常为数不多。例如伏尔加水电站,在鱼升机工作良好的情况下,过鱼量仅达电站下游河段集聚总量的1/10左右。如果鱼类集聚的地点分散,或电站的工作状况有变化的话,就要建造多个固定式过鱼建筑物。这种方案投资大,占电站建造费用的6—10％。为此,设计了一种浮动式集运过坝鱼船(见附图)。
In the case of stationary over-fishing structures, the number of broodstock capable of crossing a dam is often small due to changes in the concentration of fish in front of the power station. For example, the Volga hydropower station, in the case of good work in the fish hoist, over the amount of fish reached only about 1/10 of the total downstream of the power station. If the fish are scattered at scattered sites or when there is a change in the working conditions of the power station, a number of fixed over-fishing structures will be built. This kind of scheme invests a large amount, accounts for 6-10% of the construction cost of the power station. To this end, the design of a floating over fishing barge boat (see photo).
