高温季节养鱼.由于气候炎热,水温较高,水中各种生物的耗氧量增加.加之管理不善,鱼类就会因缺氧引起泛池泛塘或死亡.因此,改善水质是高温季节养鱼的一项不可忽视的重要工作.高温季节养鱼可用以下几种方法改善水质:(1)合理投饵施肥改善水质放的饵料要新鲜、适口,严禁投入未经加工发酵的食物和腐烂变质的草类.特别要注意不投有毒害作用的物料.一次投饵不宜过多,以防剩余饵料腐烂发醇消耗水中氧气.天气和水质较好时.投饵量可适当增加.水质透明度在20厘米以下或阴雨天.则应减少投饵.闷热天和暴雨过后,应做到不投饵.施肥应采用少施农家肥,适当增施化肥的方法来培肥水质.施肥时间应掌握在上午8—9时,下午5—6时为好.禁止在中午或雷阵雨前后施肥.施肥量应掌握宜少不宜多的原则.
Due to the hot climate and high water temperature, the oxygen consumption of various organisms in the water is increased, and in combination with poor management, the fish may cause pan-pond pan-pond or death due to lack of oxygen. Fish can not be ignored an important job .High temperature season fish can be used to improve the quality of water in the following ways: (1) a reasonable feeding and fertilizer to improve the quality of the water put bait should be fresh, palatability, non-fermentation of raw materials and spoilage is strictly prohibited spoilage Of the grass.Particular attention should be given to the material does not cast a toxic effect.One should not be too much to prevent the remaining food rotting alcohol consumption of oxygen in the water.When the weather and water quality is good.Feeding amount may be appropriate to increase. 20 cm or rainy days, you should reduce the feed .Sundable days and heavy rain, should be done without bait. Fertilization should be used less manure, fertilizers appropriate way to fertilize the water quality. Fertilization time should be in the Morning 8-9, 5-6 pm as well.No fertilizer before or after noon or thunderstorm.The amount of fertilizer should grasp the principle should be appropriate should not be more.
