The fish can attain a length of more than 40 cm. The average length of blue whiting caught off the west shores of the UK is 31 cm. A related species, southern blue whiting, ''Micromesistius australis'', occurs in the Southern Hemisphere.

Fisheries

Exploitation of blue whiting only started in the 1970s. The species, in the last decades, has become increasingly important to the fishing industries of northern European countries, including Russia.

/ref> However, recruitment of the stock fell to a low level in 2006 and has been weak ever since, causing declining spawning stock and eventually triggering strong reductions in catch quotas. The reasons for low recruitment in recent years are poorly known. The total quota for 2011 was set to 40,100 tonnes,Agreed Record of Conclusions of Fisheries Consultations between the Faroe Islands, the European Union, Iceland and Norway on the Management of Blue Whiting in the North-East Atlantic in 2011

This large increase relative to the quota in 2011 (but not to the catches in 1998–2008) is caused by a revision in the stock assessment; however, recruitment to the stock is still low and the stock is forecasted to decline. The coastal states set the total quota for 2012 to 391,000 tonnes. The fish is usually not marketed fresh, but processed into fish meal and oil. However, in Russia and in southern Europe, blue whiting are sometimes sold as food fish.

Management

Blue whiting in the northeast Atlantic is a straddling stock: it occupies the exclusive economic zone (EEZ) of the Faroe Islands, the European Union, Iceland and Norway, as well as the

high seas The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed region ...

". This means effective regulation calls for international co-operation. Quota advice for blue whiting in the northeast Atlantic is provided by ICES. For a long period, blue whiting fisheries were mainly regulated through nationally set quotas because there was no international agreement about sharing the total quota; consequently, the total catch greatly exceeded the advised quotas However, the Coastal States (the Faroe Islands, the European Union, Iceland and Norway) reached an agreement in December 2005,Press release: Broad agreement on fisheries between Norway and the EU
/ref> ending the period of what was sometimes referred to as "Olympic fishing". Since 2006, the blue whiting fishery has been regulated under this agreement, which gives the greatest share to the European Union, but through quota swaps, Norway has been holding the largest annual quotas.
