牛蛙属变温动物,当气温降到10℃左右时即冬眠。冬眠期间,牛蛙不食不动,靠消耗体内蓄积的养料维持低微的新陈代谢,以致身体消瘦、病害增多,尤其是刚变态的幼蛙易造成大批量的死亡。牛蛙冬眠并非其生长发育过程中不可缺少的生理现象,而仅是变温动物对不良的低温环境的一种适应现象。所以,只要采取措施,将养殖池的温度提高到10℃以上,就可以解除牛蛙的冬眠,使其继续生长。笔者连续3年利用塑料大棚冬季养殖牛蛙,牛蛙成活率 Bullfrog is a warm-blooded animal, when the temperature dropped to about 10 ℃ when the hibernation. During hibernation, the bullfrog can not eat without moving. By keeping the nourishment stored in the body to maintain a low level of metabolism, the body becomes thinner and diseases increase. Especially, the frog with just metamorphosis can easily cause large-scale deaths. Bullfrog hibernation is not an indispensable physiological phenomenon in the process of its growth and development, but only a kind of adaptation to the poor low temperature environment. So, as long as the measures taken to raise the temperature of the pond above 10 ℃, you can lift the hibernation of the bullfrog to continue its growth. The author for three consecutive years using plastic greenhouse winter farming bullfrog, bullfrog survival rate
