Abstract

The blue shark belongs to the group of the most widespread pelagic sharks in the world. It inha-bits the pelagic zone of almost all warm and temperate seas and oceans. As it is one of the most abundant shark species, it is frequently caught in different types of fishing gear operated in the pela-gic zone. This study provides the first data on the reproduction of this species in Montenegrin waters (in the Southeastern Adriatic Sea). Six newborn blue sharks were found during our field excursions. For three of them, detailed morphometric measurements are presented. Alongside the newborns, a gravid female was also recorded. The data was collected in the period from April to October 2017. According to the published literature and the data presented in this paper, species reproduction is likely to be seasonal. A review of the areas where the specimens were recorded was carried out in order to infer if the adult females choose them specifically as their parturition grounds

黑山(东南亚得里亚海)沿海新生蓝鲨Prionace glauca (Linnaeus, 1758)的形态测量及其潜在产区特征

蓝鲨是世界上分布最广的远洋鲨鱼之一。它栖息在几乎所有温暖和温带海洋的中上层区域。由于它是数量最多的鲨鱼品种之一，因此经常被在远洋海域作业的不同类型渔具捕获。这项研究提供了黑山水域(亚得里亚海东南部)该物种繁殖的第一个数据。在我们的实地考察中发现了六只新生的蓝鲨。对其中三种进行了详细的形态测量。除了新生儿外，还记录了一只怀孕的雌性。数据收集于2017年4月至10月。根据已发表的文献和本文提供的数据，物种繁殖可能是季节性的。对记录标本的区域进行了审查，以推断成年雌性是否专门选择它们作为分娩地点
