摘  要:
选取青岛水族馆人工繁育的4头同龄斑海豹进行了野化训练,6个月后选择117977和117978安装信号发射器,并在大连斑海豹国家级自然保护区放归自然,卫星定位监测两头海豹的GPS位点、温度和深度。结果显示,117977主要在渤海湾内活动,117978释放后最南到达浙江杭州湾,后回到释放区域,两者分别传回信号19 d和134d,预测已经融入本地群体。结果表明,人工繁殖的斑海豹在经过野化训练后,放归自然海域后可以正常生活洄游。本研究为斑海豹自然群体的资源量恢复及洄游路线研究提供了一种新的可行方法 。

摘  要:
Four seal pups bred in captivity were trained under field environmental conditions for 6months in this study.Two seal pups(numbered 117977 and 117978)were instrumented with satellite transmitters and the released in Dalian Spotted Seal National Nature Reserve(120°40'21.15 "E.37°59'35.76" N)on the 80 th anniversary of Qingdao Aquarium.The seal body temperatures,diving depths and geographic locations were recorded by GPS Tracker.Seal no.117977 survived mainly in Bohai Bay.Seal no.117978 arrived at Hangzhou Bay.then returned to the release area.The data from 117977 andl 17978 covered 19 and 134 days,respectively.We conclude that they integrated into the local wild population.Our results show that captive- bred and rewilded spotted seals can survive and migrate in nature after release.This demonstrates a feasible method for seal recovery and for study of migratory routes of natural population of spotted seals.
