(1) 测水温，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。因此，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
(1) measured water temperature, the amount of feeding bait. 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. Therefore, it is necessary to strictly determine the daily feeding amount according to the law of the annual water temperature rise and fall so that the fish eat well, grow well and get less sick. Specific methods: early spring season
