It has been estimated that 44,000 turtles die every year due to anthropomorphic activity in the Mediterranean Sea, and that longline fishing is one of the most significant causes of mortality. A total of 482 specimens of were rescued from different parts of the Sicilian coast (Mediterranean Sea) from 2014 to 2016. The most numerous stranding was recorded during the spring and summer seasons, mainly along the north and eastern coasts of Sicily. The curved carapace length for all the specimens ranged from between 19 and 95 cm and most of these were young or sub adults. The highest number of strandings was recorded in 2014 and 2015, with 206 and 169 individuals, respectively. A total of 66 live specimens out of 239 were successfully rehabilitated and released after surgery or drug therapy; fishing hooks were found in 129 specimens in different parts of the digestive tract with greater frequency in the oesophagus (47.3%) followed by the gut (24.8%), stomach (14.7%), and mouth (13.2%). This paper will highlight the incidence of the incidental catch by longline fishing of along the Sicilian coasts and also relate the size of ingested hooks to the size of examined specimens.
据估计，每年有44000只海龟因地中海地区的人类活动而死亡，延绳钓捕鱼是导致海龟死亡的最重要原因之一。2014年至2016年期间，从西西里岛海岸（地中海）不同地点共营救了482只海龟标本。搁浅数量最多的记录发生在春季和夏季，主要集中在西西里岛的北部和东部海岸。所有标本的曲甲长度在19至95厘米之间，其中大多数为幼龟或亚成龟。搁浅数量最多的年份是2014年和2015年，分别为206只和169只。在239只标本中，共有66只活体标本在接受手术或药物治疗后成功康复并放归；在129只标本的消化道不同部位发现了鱼钩，其中在食道（47.3%）出现的频率最高，其次是肠道（24.8%）、胃（14.7%）和口腔（13.2%）。本文将重点介绍西西里岛沿岸延绳钓意外捕获海龟的发生率，并将摄入鱼钩的大小与被检查标本的大小进行关联。
