摘要

本文描述了亚得里亚海沙洲鲨最南端的记录——在萨赞岛岛外120米深处的岛架上捕获的新发现的Carcharhinus plumbeus (Nardo, 1927)。个体有一个部分愈合的脐部疤痕,被认为是新生儿。被检查的鲨鱼身体状况良好,没有明显的疾病迹象,也没有明显的寄生虫。本文对亚得里亚海北部和中部的4个新生和幼鱼标本进行了详细的形态测量比较。尽管不可能确定我们的标本是出生在研究区域还是其他地方,但这一发现提供了第一个证据,表明新生儿沙洲鲨可以在阿尔巴尼亚海岸找到。了解幼鱼和幼鱼的确切位置和运动对有效的长期原位保护具有重要意义。

First record of neonatal sandbar shark Carcharhinus plumbeus (Nardo, 1827) (Carcharhiniformes: Carcharhinidae) from the Southern Adriatic Sea
This paper is describing a new finding of Carcharhinus plumbeus (Nardo, 1927) caught at the insular shelves off the Sazan Island at the depth of 120 m, which is the southernmost record for a sandbar shark in the Adriatic Sea. The individual had a partially healed umbilical scar and is considered as neonatal. Examined shark appeared in good body condition with showed no macroscopic signs of diseases or macroscopic parasites. Detailed morphometric measurements are compared with four neonate and juvenile specimens from the north and central Adriatic Sea and are provided in the paper. Despite it is not possible to establish a certain conclusion on whether our specimen was born in the studied area or elsewhere, presented finding provides the very first evidence that neonatal sandbar sharks can be found along the coast of Albania. Knowing the exact locations and movements of both neonates and juveniles is of high importance for the effective long-term in-situ conservation.
