近年来我国淡水渔业发展较快,湖泊渔业在淡水渔业生产中占有重要地位。但是应该看到,有的湖泊严重受自然条件的影响和限制,湖泊水文条件的变化引起了鱼类生态环境的变化,造成了鱼产量下降。因此,如何总结经验教训,发展湖泊渔业是值得研究和探讨的问题。 一、湖泊生态环境与产量的关系 俗话说:“宽水养大鱼”。这句话是广大渔业生产者在长期的生产实践中得出的结论,颇有一 In recent years, the development of freshwater fisheries in China has been developing rapidly. Lake fisheries occupy an important position in the production of freshwater fisheries. However, it should be noted that some lakes are severely affected and restricted by natural conditions. Changes in lake hydrological conditions have caused changes in the fish’s ecological environment, resulting in a drop in fish production. Therefore, how to summarize the experiences and lessons and develop the fishery of lakes is worth to be studied and discussed. First, the relationship between lake ecological environment and yield As the saying goes: “wide water raise big fish.” This remark is quite a conclusion reached by the majority of fishery producers in their long-term production practices
