近年来,各地鳖、鲶(革胡子鲶)、蛙(牛蛙)、虾(青虾)等特种水产养殖业的发展势头十分迅速。但鳖、鲶、蛙、虾均只能适应较高水温而耐寒力差,当水温降至12℃以下时,即进入冬眠或出现摄食减少。若越冬保护不当,则会延缓生长周期,产量低下,甚至造成大批死亡,给饲养、繁殖带来严重的威协。为此,笔者先后实地 In recent years, special aquaculture industries such as turtle, catfish (catfish), frog (bullfrog) and shrimp (freshwater shrimp) have enjoyed rapid development. However, turtle, catfish, frogs, shrimp are only adapted to higher water temperature and poor cold resistance, when the water temperature dropped below 12 ℃, that is, into the hibernation or decreased food intake. If overwintering protection is improper, it will delay the growth cycle, low output, or even cause a large number of deaths, to feed, breeding a serious threat. To this end, I have field
