Abstract

This working document presents the results of the most significant deep-sea fish species caught in 2022 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. Overall, the biomass of these target species increased in this last survey, except for P. blennoides and M. macrophthalma. Despite that raise, the recruitment was poor.
