2023 Celtic Sea Herring Acoustic Survey (CSHAS)

This survey continues 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.

The survey will take place from the 9th to 29th of October.

The Celtic Sea Herring Acoustic Survey is an excellent opportunity for graduates and postgraduate students who wish to develop field skills and careers in fisheries acoustics, and fisheries biometric and plankton sampling. Data collection also extends to marine mammals and seabirds.


The closing date for applications for applications is Friday the 11th of August 2023.
