Abstract
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
