Results on silver smelt (Argentina silus and A. sphyraena), bluemouth (Helicolenus dactylopterus), greater forkbeard (Phycis blennoides), roughsnout grenadier (Trachyrincus scabrus), Spanish ling and ling (Molva macrophthalma and Molva molva) from the Porcupine Bank Survey (NE Atlantic)

Abstract

This working document presents the results of the most significant deep fish species caught in 2020 on the Porcupine Spanish Groundfish Survey (SP-PORC-Q3). Biomass, abundance, geographical distribution and length ranges were analysed for silver smelt (Argentina silus and A. sphyraena), bluemouth (Helicolenus dactylopterus), greater fork-beard (Phycis blennoides), roughsnout grenadier (Trachyrincus scabrus), Spanish ling and ling (Molva macrophthalma and Molva molva) and other scarce deep sea species. The biomass of most of these species decreased this last survey, only A. silus and P. blennoides increased, althought H. dactylopterus increased in abundance. Signs of recruitment have been found for H. dactylopterus and T. scabrus
