    • Cruise Report Biological Sampling Survey 2006: Irish Sea 24 February to 5 March

      Marine Institute (Marine Institute, 2007)
      The survey is intended to address the requirements of the Data Collection Regulation 1639/2001. Information on growth, maturity and sex ratio (biological data) were collected for a range of commercially important species. Ovary samples were collected to validate visual maturity staging and to provide fecundity samples for the Irish Sea Egg Production Project in collaboration with CEFAS (Lowesoft) and DARDNI (Belfast). Samples of various squid species were collected for genetic analysis by ANFACO-CECOPESCA (Vigo, Spain).
    • Cruise report: Irish Anglerfish & Megrim Survey 2016

      Gerritsen, H.D.; Kelly, E.; Stokes, D.; Ni Chonchuir, G.; Moore, S.J. (Marine Institute, 2018)
      The 2016 Irish Anglerfish and Megrim Survey (IAMS) took place from 4-24th January and 25th February to 6th March 2016 on RV Celtic Explorer. The main objective of the survey is to obtain biomass estimates for anglerfish (Lophius piscatorius and L. budegassa) in and establish an abundance index for megrim (Lepidorhombus whiffiaginis and L. boscii) in VIa (south of 58°N) and VII (west of 8°W). Secondary objectives are to collect data on the distribution and relative abundance of anglerfish, megrim and other commercially exploited species. The survey also collects maturity and other biological information for commercial fish species. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim survey (SIAMISS) and uses the same gear and fishing practices.

      The 2017 Irish Anglerfish and Megrim Survey (IAMS) took place from 14th February to 7th March (area 7bcjk) and 8-17th April 2017 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass estimates for anglerfish (Lophius piscatorius and L. budegassa) and establish an abundance index for megrim (Lepidorhombus whiffiaginis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution and relative abundance of anglerfish, megrim and other commercially exploited species.

      Kelly, E.; Stokes, D.; O'Cuaig, M.; Moore, S.J.; White, J.; Bouch, P.; Gerritsen, H.D. (Marine Institute, 2019)
      The 2019 Irish Anglerfish and Megrim Survey (IAMS) took place from 1-25th March (area 7bcjk) and 16-25th April 2019 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass and abundance indices for anglerfish (Lophius piscatorius and L. budegassa) and megrim (Lepidorhombus whiffiagonis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution, relative abundance and biology of other commercially exploited species. This year, additional sampling took place in deep water (up to 1,500m) in order to monitor the recovery of exploited deep-water species following the decline of the deep-water fisheries in Irish waters. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim Survey (SIAMISS) and uses the same gear and fishing practices.
    • Cruise Report: Irish Beam trawl Ecosystem Survey 2016

      Gerritsen, H.D. (Marine Institute, 2018)
      The first annual Irish Beam trawl Ecosystem (IBES) took place from 6-16th March 2016 on RV Celtic Explorer in the western Celtic sea. The main objective of the survey is to connect the Irish Anglerfish and Megrim Survey (IAMS) to the UK beam trawl surveys in the Celtic Sea, English Channel and Irish Sea, with the purpose of providing a swept-area biomass estimate for anglerfish (Lophius piscatorius and L. budegassa) in area VII. Secondary objectives are to collect data on the distribution and relative abundance of commercially exploited species as well as invertebrates and by-catch species, particularly vulnerable and indicator species. The survey also collects maturity and other biological information for commercial fish species in the western Celtic Sea. The IBES survey is coordinated with the CEFAS Q1 South-west Ecosystem Survey (Q1SWECOS) and uses the same gear and methods.
