牛蛙(含美国青蛙)均有着冬季休眠的生活习性,冬季水温下降至10℃以下时,便躲藏在洞穴中或水中淤泥里,停止活动、摄食。当气温回升到10℃以上时,又出来活动觅食,即使冬天也是如此。蛙类在冬眠期的生活阶段很重要,直接关系到其体质状况、成活率的高低。为使牛蛙安全越冬应做到四注意: 一、注意投喂适口饵料:在牛蛙未进入冬眠时,应投喂适口饵料,蝌蚪以麦麸、米糠、豆浆等富含蛋白质的饵料为主,而幼蛙、成蛙则主投动物性饵料,如蛆虫、蚯蚓、蚕蛹以及蛙用膨化颗粒饵料等高脂肪饵料,增加其体脂,以补偿牛蛙在冬眠期的能量消耗。二、注意清整好冬眠场地:为保持越冬池清洁,应彻底更换池水,并用0.7ppm
The bullfrogs (including American frogs) have the habit of sleeping in winter. When the water temperature drops below 10 ° C in winter, they hide in the caves or in the mud in the water and stop eating and eating. When the temperature rose to above 10 ℃, it came out activity foraging, even in winter as well. Frog in the dormant stage of life is very important, directly related to their physical condition, the level of survival. In order to ensure the safety of the bullfrog overwintering should pay attention to four: First, pay attention to feeding palatable bait: bullfrog did not enter the hibernation, should be fed palatable bait, tadpoles to wheat bran, rice bran, soy protein-rich bait-based, Frog, into the frog is the main animal feed bait, such as maggots, earthworms, pupae and puffed frog with pelleted food such as high-fat bait to increase its body fat to compensate for the energy consumption of bullfrog during hibernation. Second, pay attention to clean the hibernation site: In order to maintain the winter pool clean, the pool water should be completely replaced, and with 0.7ppm
