Unexpected deep‐sea fish species on the Porcupine Bank (<scp>NE</scp> Atlantic): Biogeographical implications

Abstract 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 Ocea...

Description
Summary:Abstract 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 Cataetyx alleni DNA barcode to be obtained for the first time. 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.
