Three species of wolfish — Atlantic wolffish (Anarhichas lupus), Spotted wolffish (Anarhichas minor), and Northern wolffish (Anarhichas denticulatus) — live in the Barents Sea.  The abundance and biomass of all three species is relatively low (Figure 4.3.48), but they are all widely distributed throughout the Sea. The stock size of Atlantic wolffish and spotted wolffish, as measured by area-swept-clear estimates, has been relatively stable since 2004; the Northern wolffish has varied between 35,000

and 90,000 tonnes. Area-swept-clear estimates of stock size are based results from the Joint Norwegian/Russian Survey of the Barents Sea Ecosystem (ICES AFWG, 2014).
