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紧密的关系,要使鱼长快而又少发病,必须根据全年水温升降规律而严格确定鱼塘日投饵量,使鱼吃好长快。如以草、鳊鱼为例,早春时节当水温上升到7℃以上时,就必须投喂商品饲料和鲜嫩草。每天一次,每次喂量首先为当日存塘草、鳊等吃食性鱼体重3～5%,然后 1. Temperature measurement of water feeding. Fish is a warm-blooded animal, its digestion and feeding intensity and water temperature are closely related to make the fish grow faster and less incidence, according to the law of the annual water temperature rise and strict determination of fish ponds to feed the amount of fish to eat long . Take grass and anchovy as an example. When the water temperature rises above 7 ℃ in early spring, it must be fed with commercial feed and tender grass. Once a day, each feed is first deposited on the same day ponds, 鳊 and other eating fish body weight 3 ~ 5%, then
