一种原产于北美洲的美国青蛙,学名为沼泽绿蛙,1987年首次引入我国,1989年引入我市,现已在我站繁殖饲养成功。这种美国青蛙成熟个体重约500克,除体色为浅绿色,背部及腿上有黑色斑点外,其形态特征与目前国内饲养的牛蛙相似。与牛蛙相比,该蛙有如下优良之处: 1、生长周期长,对温度的适应性强。该蛙的适宜生长温度为6—37℃。最适生长温度为18—32℃,在6℃下仍能摄食生长,只有当温度降至0℃时才进入冬眠。因此,该蛀非常适合在我省气候条件下人工饲养。 2、生长速度快。蝌蚪经60—80天变态为约
An American frog native to North America with the scientific name Marsh Green Frog, was first introduced into China in 1987 and introduced to our city in 1989 and is now successfully reared in our station. This American frog mature individual weighs about 500 grams, in addition to body color is light green, black spots on the back and legs, the morphological characteristics similar to the current domestic bullfrog. Compared with bullfrog, the frog has the following advantages: 1, long growth cycle, the adaptability to temperature. The frog suitable growth temperature of 6-37 ℃. The optimum growth temperature is 18-32 ℃, still can feed the growth at 6 ℃, and only enter the hibernation when the temperature drops to 0 ℃. Therefore, the moth is very suitable for artificial feeding in our province’s climatic conditions. 2, fast growth. Tadpole metamorphosis of about 60-80 days
