| Summary: | ICES has examined the proposed methods for apportioning ICES advice among the existing management areas. Relevant background information regarding stock structure, historic fisheries, and management measures for roundnose grenadier in the northeast Atlantic are presented. While studies suggest the existence of population structure within roundnose grenadier from subareas 5, 6, 7, and 12, available results are insufficient to delineate alternative stock boundaries to those currently used in the northeast Atlantic. The bulk of the biomass of roundnose grenadier in the Atlantic basin occurs at depths below 800 m. As a result, most roundnose grenadier are no longer accessible to commercial fishing, as bottom trawling is not permitted at depths below 800 m and gillnetting is not permitted below 600 m in EU and UK waters. Landings have decreased in all areas during the past decade, reflecting the overall decrease in fleets engaged in deep-water bottom trawling. Total catches since 2016 have been very low in ... |
