稻田养殖美国青蛙试验

Studies on the Culturing of Rana grylio in Paddy Field

利用稻田养殖美国青蛙，放养平均重 ５０ ｇ的幼蛙，经过 ４个月的养殖，平均规格达 ２５０ ｇ，亩产 ２２０ ｋｇ，成活率８５％，水稻亩产４０７．ｋｇ，每亩收入４ ８１８元。试验表明，稻田养蛙生态农业确实可行。

Culturing Rana grylio whose average size is 50 g in paddy field. After 4 months,the average size reached 250g and survival rate was 85%,the yield of Rana grylio was 220 kg per mu while the output of rice was 407 kg. This experiment showed that the net profit was 4 818 yuan per mu and the culturing of Rana grylio in the paddy field was one of the effective ways to obtain high profit.
