This report provides the main results of the twelfth underwater television survey of the various Nephrops patches in Functional Unit 19. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. In 2022 a total 42 UWTV stations were successfully completed. The mean density estimates varied considerably across the different patches. The 2022 raised abundance estimate showed a 4% decrease from the 2021 estimate and at 259 million burrows is below the MSY Btrigger reference point (430 million). Using the 2022 estimate of abundance and updated stock data implies catch in 2023 that correspond to the F ranges in the EU multi annual plan for Western Waters are between 302 and 338 tonnes (assuming that discard rates and fishery selection patterns do not change from the average of 2019–2021). One species of sea pen was observed; Virgularia mirabilis which has been observed on previous surveys of FU19. Trawl marks were observed at 12% of the stations surveyed
