2022 Celtic Sea Herring Acoustic Survey (CSHAS)
This survey contributes to a time series used to track the biomass and abundance of herring in the Celtic Sea and informs stock assessments by ICES expert groups. Mr Ciaran O’Donnell will lead an experienced team of biologists from the Marine Institute on survey transects deploying a pelagic trawl to ground truth echo traces of herring and other pelagic species.
