WGIPS has expertise in the design and implementation of larval surveys and acoustic-trawl surveys, including sampling of additional ecosystem parameters.
The group covers three herring larval surveys in North Sea, Irish Sea, and Western Baltic; four international and five national acoustic surveys are managed across the North Sea, West of Scotland, Malin Shelf, Western Baltic, Northeastern Atlantic, Norwegian Sea, and Barents Sea.
The present group was established in 2011 by merging WGIPS, covering larval and acoustic surveys in the North Sea, West of Scotland, Malin Shelf, and Western Baltic, with WGNAPES, which covered acoustic surveys in Northeastern Atlantic, Nordic Seas and Barents Sea. Participants come from Denmark, Norway, Russia, Island, the Faroes, the UK, Ireland, the Netherlands, and Germany.
The development and standardization of both larval and acoustic surveys is also in focus, and manuals for both types of surveys have been published.
WGIPS supports HAWG and WGWIDE with fishery-independent abundance results for assessment.
