ICES summarizes new bycatch information on marine mammals, seabirds, marine turtles, and fish in 2021, based on reported bycatch data received through the ICES data call. ICES reiterates that current bycatch monitoring activities and sampling design in most cases do not yet allow for robust and unbiased estimations of numbers of sensitive species caught incidentally in fishing activities. In the absence of estimations of absolute numbers, multiannual average bycatch rates are used to highlight species, métiers, and ecoregions where bycatch may be of particular concern. This information can be used to prioritize species or fishing métiers for monitoring and management measures. In 2017–2021, the highest bycatch rates for mammals were observed for harbour seals and harbour porpoises in set gillnets in the Icelandic Waters ecoregion, for grey seals in set gillnets in the Celtic Seas ecoregion, and for common dolphin in pair trawls in the Bay of Biscay and Iberian Coast ecoregion. For seabirds, the highest ...
