Wikipedia Abstract

Coalfish redirects here; that is also a common name for Anoplopoma fimbria in Canada. Pollachius virens is a species of marine fish in the Pollachius genus. Together with Pollachius pollachius it is generally referred to in the U.S. as Pollock. Other names include the Boston blues, coalfish (or coley) and saithe in the UK. This species can be separated from P. pollachius by looking at the relative lengths of the upper and lower jaws. P.
