Provisionally accepted species. This species is probably a synonym of Gadus chalcogrammus Pallas, 1814 (endorsed in ECoF). More studies are needed for a complete revision of all species of Gadidae.
More studies are needed for a complete revision of all genera of Gadidae.
In the past decade, a number of molecular works have shown that T. finnmarchica is likely a synonym of T. chalcogramma, although none of these works had a conclusive statement with a complete taxonomic re-assessment. However, this conclusion can be retained for scientific publications. FAO will not change it until a more stable consensus is reached. Since this species is highly commercial, with a number of regulations and statistical reports using that name, it is preferable to change it with the strongest scientific support. In addition, they are other taxonomic issue in that family, with the same issues about names. Therefore, for the use by the rest of the society, the fishery domain in particular, we recommend to continue using T. finnmarchica and wait that a complete revision of the family and thorough taxonomic and nomenclatural decisions are published.
