  • Western Irish Sea Nephrops Grounds (FU15) 2019 UWTV Survey Report and catch options for 2020

    Lundy, M.; McCorriston, P.; McCausland, I.; Erskine, K.; Lilley, K.; Heaney, G.; McArdle, J.; Buick, A.; Graham, J.; Reeve, C.; et al. (Marine Institute, 2019)
    This report provides the main results and findings of the 17th annual underwater television survey on the ‘Irish sea west Nephrops grounds’ ICES assessment area, Functional Unit 15. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. The 2019 design consisted of a randomised isometric grid of 100 stations at 4.5 nautical mile intervals out over the full known extent the stock. The resulting krigged burrow abundance estimate was 4.4 billion burrows. This was a similar result of that obtained in 2015, but a 10% lower than the abundance in 2018. In contrast to 2017 the spatial distribution of burrows shows a high density band on the central western area of the survey ground. The abundance remains within previously observed ranges and is above MSY Btrigger. The CV (or relative standard error) of 3% is in line with previous estimates and well below the upper limit of 20% recommended by SGNEPS 2012. Total catches and landings options at various different fishing mortalities were calculated and fishing at Fmsy in 2020 implies a total catch option at Fmsy (=Fmax) of 10,377 tonnes estimated to result in landings of no more than 8,546 tonnes. Sea-pens were observed at 21% of stations with high densities observed in the south-west of the ground. Trawl marks were noted at 15% of the UWTV stations.
  • Herring Fisheries on the South and South-West Coasts 1971-72

    Molloy, J. (Department of Agriculture and Fisheries (Fisheries Division), 1972)
    The 1971/72 winter herring fishery off the south coast began in the week ending 30 October, 1971, and ended on the 23 February, 1972. The total landing of 79,792 crans was over 30,000 crans (-28%) less than the total landed in the record previous season of the 1970/71. Most of the landings were auctioned at either Dunmore East or Cobh, although small quantities on occasion were landed at Kilmore Quay, Ballycotton and Kinsale. Eighty-three boats - three more than in 1970/71 season - took part in the fishery at various times throughout the season and landings were made on 77 days out of possible 103.
