在渔业生产中,因受天气变化的影响,造成严重损失的事例不少。如1992年冬季,郑州市密县李湾水库,网箱养鲤鱼由于没有及时沉箱,死鱼达4000多公斤,损失2万多元;1992年,驻马店地区遇到了特大干旱,宿鸭湖水库投放的十几吨蟹苗收获甚少,损失45万元;近几年春季,不少单位到南方购买鱼苗,由于受到寒流的影响,造成鱼苗全部死亡,损失严重。 如何减少天气变化给渔业生产带来的损失,笔者谈几点看法。 一、建立高标准的商品鱼基地(良种场、渔场),完善渔业设施,提高抵御自然灾害的能力。商品鱼基地要有一定的防洪标准,做到水、电、路三通,配备增氧机械或增氧药品,水源有保 In fishery production, there are many cases of serious losses caused by weather changes. For example, in the winter of 1992, there was a loss of more than 4,000 kilograms due to the lack of timely caissons and cage carp in the Liwan reservoir in the densely populated county of Zhengzhou City. In 1992, the drought in Zhumadian district was exasperated and the reservoir of Suyahu Reservoir was put on Of the dozens of tons of crabs harvested little, the loss of 450,000 yuan; in recent years, many units to the south to buy fry, due to the impact of the cold, resulting in all fry died of serious losses. How to reduce the loss caused by the change of weather to fishery production? First, to establish a high standard of commodity fish base (breeding grounds, fisheries), improve fisheries facilities, improve the ability to resist natural disasters. Commodity fish base to have some flood control standards, so that water, electricity, roads and three links, equipped with oxygen machinery or oxygen drugs, water source insurance
