Trends in stock biomass (a. for pelagics; b. for demersals), catches (c) and mean fishing mortalities (d), for species exploited in the Celtic/Biscay ecosystem. Catches refer to all species while biomass and fishing mortalities only include stocks assessed by ICES. For visual representation of trends, the missing biomass in the early period have been estimated proportionally to Statlant catches (hatched areas of time series; not used in the Ecosim model).
