Report of the Working Group on the Biology and Assessment of Deep-sea Fisheries Resources (WGDEEP). 24 April–1 May 2017 Copenhagen, Denmark

WGDEEP met at ICES Headquarters in Copenhagen, Denmark on 24th April to 1st of May 2017. The group was chaired by Pascal Lorance from France and Gudmundur Thordarson from Iceland. Terms of Reference of the Working Group are given in Sec-tion 2. WGDEEP gives advice according to an advice schedule where, in short, half of the stocks advice is given in year y and the other half has advice in year y+1. The excep-tion from this schedule is stocks from ICES Division 5.a (Iceland) that have advice annually. Available time-series for international landings and discards, fishing effort, survey indices and biological information were updated and for all stocks and are presented in Sections 4 to 15 of the report. In response to a request from the NEAFC, the working group update descriptions of deep-water fisheries in the NEAFC and ICES areas by compiling data on catch/landings, fishing effort and known spawning areas and areas of local depletion at the finest spatial resolution possible by ICES Subarea and division (Chapter 16)
