夏季气温高,是精养成鱼的生长旺期,只要认真搞好饲养管理,就能获得稳产高产。一、增加饲料投喂。从7月至9月份,应逐步增加饲料。精饲料的日投喂量可按池内鱼体重的5%-7%计算,草料的日投喂量可按鱼体重的80%-100%计算,每天在上午9时、下午4时分两次投至食台。遇低温阴雨天气,可少投或不投,以免饲料浪费。对鱼池施肥,应以化肥为主,能迅速繁殖出大量的浮游植物,为鱼提供生物饲料。一般每5~7天施用一次尿素,每次亩施2.5-3公斤,用水溶释后全池泼洒。要注意保持池水质肥、活、爽。二、加强防汛抗旱。夏季早涝灾害较多,尤其是在多雨季节,要日夜巡塘,防止大雨冲毁或漫过圩堤,造成成鱼外逃。三、抓好水质调节。夏季池塘
High summer temperatures, is the growth of intensive fish growth period, as long as careful management of feeding well, you can get stable and high yield. First, increase feed rationing. From July to September, feeds should be gradually increased. The daily feed of refined feed can be calculated according to 5% -7% of the body weight of the fish in the pond. The daily feed amount of forage can be calculated according to the 80% -100% of the body weight of the fish, and is cast twice daily at 9:00 am and 4:00 pm To Taiwan Case of rainy weather, you can vote less or not to avoid feed waste. Fertilization of fish ponds should be based on chemical fertilizers, can quickly produce a large number of phytoplankton for the fish to provide biological feed. The general application of urea every 5 to 7 days, each mu Shi 2.5-3 kg, dissolved in water Quanchiposa. Pay attention to keep the water quality fertilizer, live, cool. Second, to strengthen flood control and drought relief. Early summer floods more, especially in the rainy season, day and night Xun Tong, to prevent heavy rain washed away or over the dike, resulting in adult flight. Third, do a good job of water quality regulation. Summer pond
