Report of the Workshop on evaluating current national acoustic abundance estimation methods for HERAS surveys (WKEVAL)

The Workshop on evaluating current national acoustic abundance estimation methods for HERAS surveys (WKEVAL), chaired by Ciaran O’Donnell, Ireland, met at ICES Headquarters from 24–28 August 2015. The aims of the workshop were to review and evaluate current national acoustic abundance estimation methods for HERAS surveys and to initiate the steps required to implement the move to a new database for the storage of disaggregated survey data, use StoX to calculate ‘global’ biomass estimates and to populate the database with disaggregated historic survey data.
