WKCOFIBYC was convened to develop a list of species of conservation and/or bycatch interest,  that could be used to prioritize and plan for future work within ICES. WKCOFIBYC compiled a  list of fish species (including non-commercial and commercial) of conservation concern (threatened, sensitive, or already listed in legislation) that could be included in future assessments by  ICES. This is termed the Comprehensive Species List (CSL). This list is composed of international  and national hard law, along with national hard law designations, in addition to relevant red  lists of extinction risk and various academic exercises to identify sensitive species. Through the  work of WKCOFIBYC, for the first time, lists of priority sensitive species for future conservation/biodiversity-concern assessment have been developed: the regional assessment lists (RALs).  The workshop also compiled ecoregion-level lists (regional bycatch lists or RBLs) of fish species  of bycatch concern, which can be used for future planning. To avoid duplication, the RALs and  RBLs exclude species for which ICES or other bodies already provide quantitative assessments.  Additionally, the RBLs exclude most remaining species already advised upon by ICES or equivalent bodies. A set of guidelines for establishing assessment units are presented in the report.  
This process started by identifying over 4501 species from the Northeast Atlantic and the Mediterranean, including some brackish water and diadromous species, from the ‘Lists of Fishes of  Conservation Interest’. However, 1282 of these species were deemed not relevant, mainly due to  not being representative of the main fish fauna of the regions (as determined by regional experts)3. The list is structured by relevance, geography, and according to which legal, scientific,  or other designations of being sensitive to overexploitation were relevant. The ICES ecoregions  or Mediterranean subregions where the species occur are indicated. Also, the listing of each species in hard and soft law is noted. Hard law includes the EU Habitats Directive, the Common  Fisheries Policy Prohibited Species list, and (where EU law may not apply)4 national legislation  in the UK and Iceland. Where species are listed in various Red Lists of extinction risk, this is also  noted.
The methodology by which the lists were compiled is provided. A key challenge for ICES will  be to maintain the list and ensure it remains current. As WKCOFIBYC is a one-off initiative, it  remains unclear how the lists will be maintained going forward. The attention of ACOM is  drawn to this matter.
