Abstract

The content of 53 micro- and ultramicroelements in otoliths of two deep-sea fish species, blue antimora Antimora rostrata from the Northwest Atlantic (NWA) and Pacific flatnose Antimora microlepis from the Northeast Pacific (NEP), is studied. The otoliths of these species were characterized by the maximum concentration of strontium, nickel, zinc, barium, chromium, copper, lithium, cobalt, and zirconium (in descending order). The content of barium, tungsten, and lithium was higher in otoliths of the former species, while that of yttrium and uranium, in otoliths of the latter. This is probably due to differences in the chemical composition of NWA and NEP waters, as well as to differences in the linear size of fishes and changes in the concentrations of individual elements during ontogeny. The lead, arsenic, zinc, copper, and nickel contents in the otoliths, kidneys, muscles, and liver of fishes from different areas are compared.

蓝色Antimora Antimora rostrata和Pacific Flatnose A. microlepis（Moridae，Teleostei）耳石中的微量和超微量元素含量。

摘要

两种深海鱼类的耳石中53种微量元素和超微量元素的含量，它们来自西北大西洋的蓝色抗桑蚕（Antimora Antistraa rostrata）和太平洋扁平绒螯虾（Antimora microlepis）来自东北太平洋（NEP）的研究。这些种类的耳石的特征是锶，镍，锌，钡，铬，铜，锂，钴和锆的最大浓度（按降序排列）。前者的耳石中钡，钨和锂的含量较高，后者的耳石中钇和铀的含量较高。这可能是由于NWA和NEP水的化学成分不同，以及鱼类线性大小的差异以及个体发育过程中各个元素浓度的变化所致。比较了不同地区鱼类的耳石，肾脏，肌肉和肝脏中铅，砷，锌，铜和镍的含量。
