Mixed-fisheries advice for ICES WGHMM stocks
MetadataShow full item record
This WD summarizes the state of the art regarding mixed-fisheries advice in WGHMM, since one of its tasks this year was to discuss the extension of the mixed-fisheries approach in WGHMM stocks and areas. After reviewing the development of the mixed-fisheries approach in other areas and also the characteristics of the current mixed-fisheries forecast methodology (Fcube), it is concluded that the first step should be focused on the WGHMM Southern stocks, which are exploited in Iberian Peninsula waters (ICES Div. VIIIc and IXa). Most of them present accepted assessment, providing the biological parameters required by Fcube. Making assumptions for those stocks without analytical assessment, up to twelve stocks could be included, i.e. 5 stocks of demersal fish (Southern stocks of hake, megrim, 4-spot megrim, white and black anglerfish) and 7 Functional Units of Nephrops (FU25-31).
