(2025). The “Smalls” Nephrops Grounds (FU22) 2025 UWTV Survey Report and catch scenarios for 2026. Marine Institute UWTV Survey reporthttp://hdl.handle.net/10793/2068This report provides the main results and findings of the twentieth annual underwater television survey on the ‘Smalls grounds’ ICES assessment area; Functional Unit 22. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. A total of 45 UWTV stations were surveyed successfully (high quality image data), carried out over an isometric grid at 4.5nmi or 8.3km intervals. The precision, with a CV of 4%, was well below the upper limit of 20% recommended by SGNEPS (ICES, 2012). The 2025 abundance estimate was 23% higher than in 2024 and at 866 million is below the MSY Btrigger reference point (990 million). Using the 2025 estimate of abundance and updated stock data implies catch in 2026 that correspond to the ICES MSY approach of 2252 tonnes, assuming that discard rates and fishery selection patterns do not change from the average of 2022 - 2024. One species of sea pen was recorded as present at the stations surveyed: Virgularia mirabilis. Trawl marks were observed at 53% of the stations surveyed.enNephrops norvegicusStock assessmentGeostatisticsUnderwater television (UWTV)BenthosTechnical Report
