Between December 2015 and December 2017 a total of 63 sea turtles were recorded as being stranded along the Algerian coast. The loggerhead sea turtle Caretta caretta was the most commonly stranded species (n = 44) (69.8%), followed by the leatherback Dermochelys coriacea (n = 18) (28.6%) and the green turtle Chelonia mydas (n = 1). There was a slight dominance of the adult size class for stranded loggerhead turtles, while, for the leatherback, late juveniles and adults prevailed. Most loggerhead turtles stranded during the summer months (July and August), whereas most leatherbacks stranded during winter. The breakdown of the strandings by region shows a slight dominance along the western and central shores for C. caretta and a clear dominance in the west for D. coriacea. The primary cause of death was determined in 50.8% of the stranded turtles. Regarding the evidence of interactions with humans the major cause of stranding in loggerhead turtles was incidental catch by artisanal fisheries, followed by boats’ collisions. The main causes of leatherback strandings were boats’ collisions. Algerian data show that human activities affect loggerhead turtles and also prove a significant presence of the leatherback turtle on this coast.

阿尔及利亚（地中海西部）海龟搁浅和相关威胁的首次研究：2016–2017

在2015年12月至2017年12月之间，总共有63只海龟被困在阿尔及利亚沿海。logger海龟是最常被搁浅的物种（n = 44）（69.8％），其次是棱皮the Dermochelys coriacea（n = 18）（28.6％）和绿海龟Chelonia mydas（n = 1）。搁浅的龟在成年体型上略占优势，而棱皮龟则以晚成年和成年成年为主。大部分的龟在夏季（7月和8月）搁浅，而大多数棱皮龟在冬天搁浅。按地区划分的股线分解显示，对于C. caretta，沿西部和中部海岸略有优势，而对D. coriacea则在西部明显占优势。在50.8％的搁浅龟中确定了主要的死亡原因。关于与人互动的证据，导致龟滞留的主要原因是手工渔业的偶然捕获，然后是船相撞。棱皮龟搁浅的主要原因是船相撞。阿尔及利亚的数据表明，人类活动影响了logger龟，并且在该海岸上也证明了棱皮龟的大量存在。
