Abstract

Two species, light dusky rockfish Sebastes variabilis (Pallas) and lesser prickleback Alectridium aurantiacum Gilbert et Burke, rare in the western Bering Sea were found in this area in the summer of 2017–2018. S. variabilis was recorded at three stations between capes Olyutorsky and Navarin at the depths of 130–353 m, A. aurantiacum, far to the north beyond the known range, for the first time, in one haul at a 68-m depth near the Cape Olyutorsky. Both are warm-water affinity species; their presence in the study area is presumably associated with the currently observed period of warming in the northern Pacific Ocean.

在白令海西部的淡淡暗淡石斑鱼（Sebastes variabilis（Pallas）（Scorpaeniformes：Sebastiidae））和小Prickleback Alectridium aurantiacum（Perciformes：Stichaeidae）的记录

摘要

2017-2018年夏季，在白令海西部发现了两个物种，即淡淡的暗色石斑鱼Sebastes variabilis（Pallas）和较小的折背金莲花Alectantium aurantiacum Gilbert et Burke。首次在距离已知范围以北130.353 m的A. aurantiacum深处，在奥利多尔斯基海角和纳瓦林角之间的三个站点上记录了变异链球菌Cape Olyutorsky。两者都是温水亲和种。它们在研究区的存在可能与目前在北太平洋地区观测到的变暖时期有关。
