Haddock is a marine fish distributed on both sides of the North Atlantic. Haddock is a popular food fish and is widely fished commercially. The haddock is a rather large codfish, usual size in catches is between 20 and 26 inches long, but the largest individual fish that was caught in Icelandic waters measured 44 inches.

HaddockIt is found in abundance all around Iceland. The fish thrives in temperatures of 36 to 50°F (2 to 10°C).  The haddock is easily recognized by a black lateral line running along its white side (not to be confused with pollock which has the reverse, i.e. white line on black side) and a distinctive dark blotch above the pectoral fin, often described as a “thumbprint” or even the “Devil’s thumbprint” or “St. Peter’s mark”.

Haddock is certified since 2013 in the Iceland Responsible Fisheries certification program.
