为安全疏散蝌蚪至变态池,通过对变态幼蛙进行辅助喂养,提高幼蛙存活率以实现增产的目的,利用增氧试验对不同变态期蝌蚪的存活情况进行研究.研究了幼蛙耐饥饿极限,用2日龄蝇蛆对幼蛙进行辅助喂养试验,观察辅助喂养效果.研究表明双氧水配制的增氧液能够提高水中溶解氧浓度,有利于蝌蚪安全运送;疏散变态蝌蚪的有利时机是进入变态期后未长出前肢时进行;完成变态的幼蛙耐饥饿极限天数是6～8d,利用2日龄蝇蛆辅助喂养能够提高幼蛙存活率并实现增产.“,”In order to increase the yield,the tadpoles were safely evacuated to the metamorphosis pool and then the survival rate of the metamorphosis young Rana chensinensis were improved through the complementary feeding.The survival condition of the tadpoles in the different metamorphosis stages was studied using the oxygen aeration experi ment.The starvation tolerance of the young Rana chensinensis was studied.The young Rana chensinensis was fed with two-day-old housefly larvae to observe the effect of complementary feeding.The results showed that the concentration of dissolved oxygen in the water increased with the liquid prepared with hydrogen peroxide,which was favorable for the evacuation of the tadpoles.It was optimal that the metamorphosis tadpoles were evacuated before they grew forelimbs.The starvation tolerance of the metamorphosis young Rana chensinensis was 6-8 d.The survival rate of the young Rana chensinensis was improved through the complementary feeding with two-day-old housefly larvae to increase the yield.
