Abstract
The present paper is a follow-up of previous reports presented to the IWC Scientific Committee regarding the issue of common dolphin bycatch in the Bay of Biscay. It synthesizes available stranding and aerial survey data collected during the winter 2021. The mortality of small delphinids for the whole winter 2021 can be estimated at about 6,800 individuals. This estimate is of the same order of magnitude as those made since 2016. Therefore, it cannot be concluded that there was any decrease in the mortality of common dolphins during the winter of 2021.
