      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 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.

      The second annual Irish Beam trawl Ecosystem (IBES) took place from 7-16th March 2017 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 uses the same gear, methods and stratification as the CEFAS Q1 South-west Ecosystem Survey (Q1SWECOS). The IBES survey is formally coordinated by the ICES Working Group on Beam Trawl Surveys

      The third annual Irish Beam trawl Ecosystem (IBES) took place from 9-19th March 2018 on RV Celtic Explorer in the western Celtic sea. The main objective of IBES is to extend the geographic range of the CEFAS Q1 South-west Ecosystem Survey (Q1SWECOS), with the purpose of providing a swept-area biomass estimate for anglerfish (Lophius piscatorius and L. budegassa) in the Celtic Sea (ICES 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 uses the same gear, methods and stratification as the Q1SWECOS. The IBES survey is formally coordinated by the ICES Working Group on Beam Trawl Surveys
