摘　　要：实践过程中针对养殖方法、产卵期、孵化期、变态期以及黑龙江林蛙日活动规律进行了对比分析。结论,在每年4月28日至5月12日期间出现产卵高峰;在5～7℃、10～12℃、14～15℃池水温度范围有较高孵化率;采用混合饲料喂养的蝌蚪变态率均在68%以上;黑龙江林蛙每天9～11时和15～17时活动频繁,是最佳喂食时间;冬季经过越冬池越冬后,选择春眠后放养的技术思路,来提高幼蛙成活率,起到冬眠后的缓冲作用。在放养场内散养期间,人工控制饵料投放量,促使黑龙江林蛙主动捕食场内野生昆虫,激发林蛙适应生态环境的潜在习性。The process of practice for farming methods,spawning,hatching,metamorphosis and the rana day law were compared and concluded that from April 28 to May 12 the rana had a higher spawning rate;at 5-7℃,10-12℃,14-15℃ temperature range had a higher hatching rate;mixed fed the tadpole had a higher metamorphosis rate in more than 68%;at 9-11 and 15-17 clock the rana had a higher a ctivity rate,so it was the best feeding time;rana lived through the winter in winter pool and stocked after spring sleep,then the survival rate was improved and achieved hibernation of buffer role.Artificial control lure-analyses during the rana kepted time in stocking farm,in order to precipitate rana actively captured wild insects,inspire rana to adapt to the potential of the ecological environment habit.
