Working groups and committees

Working Group - CommitteeTasks
ICES
Working Group on International Pelagic Surveys (WGIPS)WGIPS coordinates, implements, and reports on acoustic surveys for pelagic fish species in ICES divisions 1-8 and subdivisions 21–24. WGIPS currently covers 4 internationally coordinated and 8 national surveys. These surveys provide indexes for the assessment of pelagic fish stocks in the North East Atlantic.
Working Group on Fisheries Acoustics, Science and Technology (WGFAST)WGFAST focuses on the development and application of science and technology used to observe the marine environment. WGFAST holds state-of-the-art expertise in advanced acoustic-trawl survey techniques, and employs these techniques on a wide range of platforms including research vessels, ships of opportunity, and observatories.
