Mingas was monitored for 73 days and similarly traveled along the coast, all the way to Mozambique Island and across the Mozambique Channel to the NE coast of Madagascar, traversing 3,270 km (ca 2,025 km straight distance).Finally, Esperança was tracked for 2,608 km during 187 days. This turtle travelled along the coast approximately 250 km north (straight distance) of the nesting beach and reached, what is believed to be her feeding grounds on the Mozambique coast between Macaneta and Xai-Xai. This results shows that despite being protected nationally and internationally, poaching is still a serious threat to the conservation of marine turtles in Mozambique (and in the region), which warrants further efforts for their protection.原始提供方： 沿海与海洋研究协会（Associação para Investigação Costeira e Marinha） 数据集致谢： 沿海与海洋研究协会（Associação para Investigação Costeira e Marinha） 法国海洋开发研究院（Institut Français pour L'Exploitation de la Mer） 凯洛尼亚（Kélonia） 摘要： 作为西南印度洋渔业项目（South West Indian Ocean Fisheries Project，缩写SWIOFP；网址：http://www.swiofp.net）第五组件的研究内容，3只在蓬塔杜欧鲁部分海洋保护区（Ponta do Ouro Partial Marine Reserve，缩写POPMR）筑巢的蠵龟（Loggerhead turtle）被搭载了Telonics Argos Marine Transmitters TAM-2639型卫星标记发射器。这3只蠵龟的迁徙路径迥异：Lurdes即刻开启近岸北向迁徙，在15天的监测周期内累计监测迁徙距离约634千米；其最后一次标记信号来自莫桑比克伊尼扬巴内省科科斯湾附近内陆2公里处的一间小屋旁，推测该个体已遭偷猎。Mingas的监测时长为73天，同样沿海岸迁徙，全程抵达莫桑比克岛，横穿莫桑比克海峡到达马达加斯加东北海岸，累计迁徙距离达3270千米（直线距离约2025千米）。最后，Esperança的追踪周期为187天，累计迁徙距离达2608千米；该蠵龟沿海岸向北迁徙至筑巢滩以北约250千米（直线距离）的区域，抵达了被认为是其觅食地的莫桑比克海岸马卡内塔（Macaneta）与赛赛（Xai-Xai）之间的海域。本研究结果表明，尽管莫桑比克（及该区域）的海龟已受到国内与国际层面的保护，但偷猎仍是其种群保护面临的严重威胁，因此仍需进一步加大保护力度。
