Results on main cephalopods from the 2021 Spanish Ground Fish Survey on the Porcupine bank (NE Atlantic) (Division 7c and 7k)

This working document presents the results of the most significant cephalopods caught on the Porcupine Spanish Groundfish Survey (SP-PORC-Q3) in 2021. Biomass, abundance, geographical distribution and length frequencies for Eledone cirrhosa (horned octopus), Bathypolypus sponsalis (globose octopus), Todarodes sagittatus (European flying squid), Todaropsis eblanae (lesser flying squid), Loligo forbesi (veined squid), Illex coindetii (broadtail shortfin squid), Rossia macrosoma (stout bobtail squid) and other scarce cephalopods have been analysed. The species E. cirrhosa, R. macrosoma and L. forbesi increased in terms of biomass and abundance, especially R. macrosoma, reaching the highest biomass value in the time series, whereas T. sagitattus increased only in abundance terms but decreased slightly in biomass terms. In contrast, T. eblanae and B. sponsalis decreased strongly after the high values of the previous two years, as did I. coindetii. Most of the usually scarce species increased their biomass, with the exception of H. reversa

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)

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

Results on haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangius) and Norway lobster (Nephrops norvegicus) from the Porcupine Bank Survey (NE Atlantic)

This working document presents the results on haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangius) and Norway lobster (Nephrops norvegicus) caught in the Porcupine Spanish Groundfish Survey (SP-PORC-Q3) in 2020. Biomass, abundance, distribution and length frequency were analysed. M. aeglefinus remained low in the study area, although it increased slightly, but M. merlangius grew strongly and reached the highest values in the time series. No signs of recruits for neither two species were found. In addition, the incidental species Pleuronectes platessa and Solea solea were not found in 2020 and Pollachius pollachius has never been caught in the time series. The crustacean N. norvergicus fell sharply this last survey, although the mean individual weight was slightly higher than in previous years since 2016

Results on Merluccius merluccius (hake), Lophius budegassa (black anglerfish) and Lophius piscatorius (white anglerfish), Lepidorhombus boscii (four-spot megrim) and Lepidorhombus whiffiagonis (megrim) from the 2021 Spanish Ground Fish Survey on the Porcupine bank (NE Atlantic)

This working document presents the results of Merluccius merluccius (hake), Lophius budegassa (black anglerfish), Lophius piscatorius (white anglerfish), Lepidorhombus boscii (four-spot megrim) and Lepidorhombus whiffiagonis (megrim) caught on the Porcupine Spanish Groundfish Survey (SP-PORC-Q3) in 2021. Biomass, abundance, distribution and length frequency were analysed. Biomass indices of these target species increased in this last survey, except for L. piscatorius and recruitment increased for all of them, except for M. merluccius

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 2021 Porcupine Bank Survey (NE Atlantic)

This working document presents the results of the most significant deep fish species caught in 2021 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. Both the biomass and abundance of A. sillus fell sharply in this last survey whereas A. sphyraena and T. scabrus decreased slightly. However P. blennoides and especially H. dactylopterus have increased. The species M. molva and M. macrophtalma have remained quite similar values to the previous year. Signs of recruitment have been found for P. blennoides, M. macrophtalma and H. dactylopterus

Results on Merluccius merluccius (hake), Lophius budegassa (black anglerfish) and Lophius piscatorius (white anglerfish), Lepidorhombus boscii (four-spot megrim) and Lepidorhombus whiffiagonis (megrim) from the Spanish Ground Fish Survey on the Porcupine bank (NE Atlantic)

This working document presents the results of Merluccius merluccius (hake), Lophius budegassa (black anglerfish), Lophius piscatorius (white anglerfish), Lepidorhombus boscii (four-spot megrim) and Lepidorhombus whiffiagonis (megrim) caught on the Porcupine Spanish Groundfish Survey (SP-PORC-Q3) in 2020. Biomass, abundance, distribution and length frequency were analysed. Biomass indices of these target species decreased in this last survey and recruitment remained low
