摘要:
为了解瓯江鼋Pelochelyscantorii的繁殖生物学特性,2021年10月—2022年12月,在浙江省青田县,以2015年救护的一对鼋为研究对象,开展鼋人工辅助繁育研究。结果表明,2022年7—8月,雌鼋成功产卵3窝,每窝产29~44枚卵,共116枚,其中受精102枚,受精率为88.10%;鼋卵圆形,刚性,平均质量为16.54±0.89g·枚-1,卵径3.16±0.18cm;成功孵出稚鼋86只,孵化率为84.89%,平均孵化期为57.43±4.28d;刚孵出稚鼋平均体质量为13.67±1.13g,稚鼋以活鱼苗为饵料,在温室内养殖近100d,平均体质量达172.21±38.96g,养殖成活率为100%。本研究在浙江首次将野外获得的野生鼋在人工辅助条件下实现子一代的成功繁育,对丰富瓯江水系的鼋资源水平,维持种群遗传多样性水平,促进浙江省鼋野外种群恢复等方面具有重要的意义。
Abstract:
From October 2021 to December 2022, a couple of Pelochelys cantorii rescued from Oujiang in 2015 was researched for artificial breeding. The result demonstrated that from July to August 2022, the female successfully laid 116 eggs three times with 29-44 eggs per clutch. 102 eggs of them were fertilized with a rate of 88.10%. The eggs were oval and rigid with an average weight of 16.54±0.89 g/egg, egg diameter of 3.16±0.18 cm. Under artificial conditions, 86 hatchlings were successfully hatched with a rate of 84.89%. The average incubation period under artificial temperature control was 57.43±4.28 day. The hatchlings weighed an average of 13.67±1.13 g and were fed with live fish fly in greenhouse for artificial breeding for nearly 100 days when their average weight reached 172.21±38.96 g with a survival rate of 100%.
