高温季节是鱼类主要生长期,由于水温高、投饲量大、水质变化快,因而也是事故的易发期。为了保证鱼类顺利生长,高温季节养鱼要抓“五防”: 一、防病。高温季节预防鱼病一般采用食场消毒和全池泼洒药物防治。食场消毒每10天进行一次,方法是将食场清洗干净后,每个食场用0.1—0.15kg漂白粉水溶后泼洒;全池泼洒可用1ppm的漂白粉或每亩施15—20kg生石灰,一般每半个月进行一次。二、防“反水”。“反水”是由于鳙鱼放养较少或规格小,水蚤在适宜的温度下大量繁殖而导致池水清澈见底、浮游植
High temperature season is the main growth period of fish, due to high water temperature, feeding volume, rapid changes in water quality, which is also prone to accidents. In order to ensure the smooth growth of fish, fish should be caught during the hot season, “Five”: First, disease prevention. Prevention of fish diseases in hot season general use of food disinfection and Quanchiposa drug control. Food disinfection every 10 days, the method is to clean the food court, each food court with 0.1-0.15kg bleach dissolved water splashed; Quanchiposa available 1ppm bleach or 15-20kg per acre Shi lime, generally each Half a month. Second, anti-“anti-water.” “Anti-water” is due to less stocking or smaller size anchovy, Daphnia blooming at a suitable temperature and lead to crystal clear water bottom, phytoplankton
