中文摘要:2001年来,惠东港口海龟国家级自然保护区已成功地利用卫星追踪了21只海龟的洄游路线。本文利用美国卫星信号发射器(Tag)和法国Argos系统追踪3只成年雌性绿海龟。跟踪海龟西沙南沙”26 d,二者均在海口市附近海域消失;东沙从阳江市海陵岛出发,取东南向至菲律宾,然后沿菲律宾西海岸向南,最后在巴拉望岛西侧海域逗留,共追踪111 d。该试验说明港口海龟具有不同的洄游线路,偏爱沿岸的浅海洄游;洄游路线与等温线之间无显著关系;海龟洄游具有明确的目的地。建议政府相关部门采取科学策略来保护海龟。
英文摘要:Since the Huidong Gangkou Sea Turtle Reserve was established in 1985, it has been recorded more than 1280 female green sea turtles Chelonia mydas have nested on the Sea Turtle Bay, and already released nearly 60 000 juvenile sea turtles to this day. The tests of satellite tracking sea turtles had been carried out from 2001 in China Mainland, and after that, more than 20 sea turtles’ migratory routes were tracked. In 2010, three adult female green sea turtles were tracked by using U.S. satellite signal transmitters and working with the French ARGOS CLS satellite system. Our results reveal that two turtles named “Xisha” and “Nansha”, which were tracked for 26 days respectively, both disappeared in the waters near the city of Haikou; From the Hailing island of Yangjiang city, “Dongsha” migrated southeast to the Philippines, then along the Philippines west coast to the south, finally, it sticked around in the west waters of the Palawan Island. It was tracked for a total of 111 days. This study suggests that the Gangkou sea turtles had different migratory routes, and they present a preference for shallow coastal migration, we suggest that our government take effective measures to protect sea turtles.
