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 2023 Spanish Groundfish Survey on the Porcupine Bank (NE Atlantic)

This working document presents the results of the most significant deep-sea fish species caught in 2023 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 decreased, except for A. sphyraena and H. dactylopterus reaching the highest values of the entire time series. The recruitment was poor.
