1 测水体温度定投饵量 鱼类属变温动物,其消化摄食强度与水温有关。而鱼类发病率也往往与鱼类摄食强度紧密相联。一般说,在适温范围内(7℃～32℃),水温越高,鱼的摄食量越大。为此,必须根据全年水温升降规律来严格确定日投饲量,使鱼吃好、长好、少生病。具体方法:早春时节,当水温上升到0℃～6℃以上时,每天投喂1次,每次喂量开始为当日存塘草、鳊等吃食鱼体重的3％～5％,然后逐渐增加,以防投草过量造成鱼类消化障碍而引起鱼类肠炎等疾病。5月份以后,当水温上升到15℃～20℃时,喂草量可增加到当日存塘草、
A water body temperature to determine the amount of feeding fish is a variable temperature animal, its digestion and feeding intensity and water temperature. The incidence of fish is also often closely linked with the fish feeding intensity. In general, in the temperature range (7 ℃ ~ 32 ℃), the higher the water temperature, the greater the food intake. To this end, we must strictly according to the law of the annual temperature rise and fall to vote, make the fish eat well, grow well, less sick. Specific methods: early spring season, when the water temperature rose to 0 ℃ ~ 6 ℃ above, fed 1 times a day, each feed began to save the same day pond, 鳊 and other eating fish body weight 3% to 5%, and then gradually increased , To prevent overdose of grass caused by fish digestion disorders caused by fish enteritis and other diseases. After May, when the water temperature rose to 15 ℃ ~ 20 ℃, the amount of grass fed can be increased to the same day deposit pond grass,
