Blue whiting: Small gadoid fish of the northeast Atlantic

The blue whiting is a slender silver fish found in the northeast Atlantic and Mediterranean. It supports major fisheries in northern Europe, though stocks have fluctuated due to weak recruitment and management disputes.

What it is

This species belongs to the order Gadiformes, which includes cod and haddock. It has a long, narrow body with a silvery underbelly. Adults can grow longer than 40 centimetres, though those caught near the United Kingdom average 31 centimetres. It is one of two species in its genus, distinct from the southern blue whiting found in the Southern Hemisphere.

Where it lives

The fish inhabits the northeast Atlantic Ocean, ranging from Morocco north to Iceland and Spitsbergen. It is also present in the northern Mediterranean Sea, where it can be locally common. In the northwest Atlantic, between Canada and Greenland, the species occurs but is considered rare.

Breeding and life cycle

Recruitment levels dropped significantly in 2006 and have remained weak since. This decline reduced the spawning stock biomass, leading to stricter catch limits. The specific causes for the poor recruitment in recent years are not well understood by scientists.

Fish and people

Commercial exploitation began in the 1970s. Catches rose to over one million tonnes annually between 1998 and 2008. Most of the catch is processed into fish meal and oil rather than sold fresh. However, markets in Russia, southern Europe, and Japan do sell it as food. Management involves international cooperation among coastal states.

Status and threats

Stock assessments showed a sharp decline after 2006. Quotas were cut drastically, falling to just over 40,000 tonnes in 2011. An agreement among coastal states ended unregulated fishing in 2005. Despite quota revisions, the stock was forecasted to continue declining due to low recruitment.

Questions people ask about Blue whiting

Is blue whiting eaten by people?

Yes, but mostly in Russia, southern Europe, and Japan. Most of the global catch is processed into fish meal and oil rather than being sold fresh for direct human consumption.

Where does blue whiting live?

It is common in the northeast Atlantic from Morocco to Iceland and Spitsbergen. It also lives in the northern Mediterranean. It is rare in the northwest Atlantic between Canada and Greenland.

Why did catch quotas drop so low?

Recruitment fell to low levels in 2006 and stayed weak. This reduced the spawning stock, forcing managers to cut quotas significantly to protect the population from further decline.
