Four specimens corresponding to three rare deep-water fish species were caught on the Porcupine Bank (Northeast Atlantic) in September 2019. These catches include the new northernmost records of Azores rockling Gaidropsarus granti and Deep water dab Poecilopsetta beanii in the Atlantic Ocean and the second record of the latter species in its eastern zone. Three of the specimens were retained and their molecular identification also allowed the first time to obtain the Cataetyx alleni DNA barcode. The appearance of P. beanii, a West Atlantic species, in its eastern zone is discussed in relation to a possible phenomenon of transoceanic drift in the larval stage.

豪猪银行（大西洋东北部）上出乎意料的深海鱼类：生物地理意义

2019 年 9 月在豪猪银行（东北大西洋）捕获了对应于三种稀有深水鱼类的四个标本。 这些捕获物包括亚速尔群岛岩石 Gaidropsarus granti 和深水 dab Poecilopsetta beanii 在大西洋的最北端新记录和第二个后者物种在其东部地区的记录。其中三个标本被保留，他们的分子鉴定也使第一次获得了Cataetyx alleni DNA条形码。P. beanii，一种西大西洋物种，在其东部地区的出现与幼虫阶段跨洋漂移的可能现象有关。本文受版权保护。版权所有。
