高温季节是渔业生产的黄金季节,为确保全年渔业丰产丰收,取得良好的经济效益,现将高温期渔业生产管理技术要点介绍如下: 一、水质控制 高温季节,投饵比较多,水质变化快,搞好鱼池的水质调节,是获得高产稳产的一条重要措施。水质调节主要是提高水中溶氧量,减少耗氧量和氨氮含量,控制池水透明度在30—40cm。调节的方法有:①时加注新水,排除老水。加注新水能带进氧气和老水中缺乏的某些微量元素,且冲淡鱼塘水中的有机
High-temperature season is the golden season of fishery production, in order to ensure full-year high-yield fisheries harvest, and achieved good economic benefits, the high-temperature fisheries production management techniques are summarized as follows: First, the water quality control season, more feeding, water quality changes quickly It is an important measure to achieve high and stable yield by improving the water quality of fish ponds. Water quality regulation is mainly to improve the amount of dissolved oxygen in the water to reduce oxygen consumption and ammonia nitrogen content, control of water transparency in the 30-40cm. Adjustment methods are: ① when the new water, remove the old water. Filling new water can bring some of the trace elements that are lacking in oxygen and old water and diluting the organic
