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 2021. Biomass, abundance, distribution and length frequency were analysed. The biomass of these two fishes decreased compared to the previous year. Signs of recruits were found for both species, especially for M. aeglefinus. In addition, the incidental species Pleuronectes platessa and Solea solea were not found in 2021 and Pollachius pollachius has never been caught in the time series. The crustacean N. norvergicus has increased slightly in this last survey and has done so for all the groups of sizes, thought more markedly in those larger than 21 mm. However, the mean individual weight was slightly lower than in previous years.
