利用卫星标记跟踪方法对斑海豹的野外释放效果进行了研究。2010年和2011年6月分别释放了4头和3头人工繁殖的2龄未成年斑海豹,2011年同时释放了3头野外出生的救助个体。标记斑海豹在释放后,7头人工繁殖斑海豹中的5头信标信号持续时间较长,在信号消失前,1头斑海豹一直在渤海海域活动,另4头沿辽宁沿岸、朝鲜西海岸到达辽东湾斑海豹的主要度夏海域韩国白翎岛附近。研究期间,1头人工繁殖的斑海豹在59 d内运动的距离超过1 250 km。救助斑海豹中,2头个体的信标信号持续较长,并分别在山东半岛沿海和黄渤海活动。研究结果表明,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。
The effect of field release on seal seals was studied by using satellite marker tracking method. In 2010 and June 2011, 4 and 3 artificially propagated 2-year-old juvenile harbor seals were released respectively. In 2011, 3 wild-born rescue recipients were also released. After the seal was released, the five beacon signals of the seven captive seals kept longer. Before the signal disappeared, one of the seal seals had been operating in the Bohai Sea and the other four had arrived along the coast of Liaoning and the west coast of North Korea The main degree of Liaodong Bay Harbor Seal The summer sea area near Paekeling. During the study period, a man-made harbor seal moved more than 1,250 km within 59 days. In the rescue harbor seal, the beacon signals of two individuals last longer, and they are respectively active in the coastal areas of Shandong Peninsula and the Yellow Sea and the Bohai Sea. The results show that the artificial breeding of seals seal after wild training, after release into the natural waters can migrate to normal life.
