美国青蛙在我国养殖历史较短,各地养殖方式也不同,在广东以投喂鲜活饲料,而我省以干饲料为主。其生长速度不如古巴牛蛙,但肉质优于古巴牛蛙,在市场上其经济价值较高,在人工养殖条件下由于密度大,容易感染疾病和大小残食,若防治失误,将会造成很大损失。现将我场两年的试养情况小结如下: 1 试养条件 1.1 蛙池,系旧鱼苗池改建而成,1.8—25m~2大小不等,共16个。试养面积1992年158m~2;1993年扩大到469m~2,四周建
American frogs have a short history of breeding in our country and have different ways of farming. In Guangdong, live feed is fed to them while dry feed is mainly used in our province. Its growth rate is not as good as that of Cuban bullfrog, but its flesh quality is superior to that of Cuban bullfrog. Its economic value is higher in the market. Due to its high density under the condition of artificial breeding, it is easy to infect the disease and the size of residual food. If the prevention and control error, it will cause great losses . Now my field two years trial summary is as follows: 1 trial conditions frog pond, the Department of the old fry pond rebuilt, 1.8-25m ~ 2 sizes, a total of 16. Trial area of 158m ~ 2 in 1992; expanded to 469m ~ 2 in 1993, built around
