Beautiful tigerstripes of black and green blue are unmistakable. Mackerel is a delicious fish, closely related to tuna, its moist flesh is high in omega 3 oils and is best eaten when very fresh, barbequed, baked or raw as sushi.
One of the best Cornish seafood choices, delcious and very good for you. Cornwall's mackerel, the majority of which are handline caught, are very hard to beat. Stocks across europe are declining but within Cornish waters industrial fishing targeting mackerel is banned. traditional small scale fishing vessels target mackerel with simple handlines which are a selective and low impact method that produces the finest quality product.

Mackerel are fast swimming, migratory, shoaling fish that range all around the North East Atlantic. They feed on plankton and small fishes and come into Cornish waters in huge numbers at certain times of year. Juvenile mackerel grow quickly and can reach 22cm after one year, and 30cm after 2 years. Mackerel can attain a maximum length of about 70cm and weight of 3.4kg.They may live for more than 20 years. By 3 years old, most mackerel are mature (at a length of approximately 28cm). Females shed their eggs in about twenty separate batches over the course of the spawning season. Mackerel are batch spawners, they spawn mainly in March to July; the eggs and larvae are pelagic. During this time spawning fish are not targetted as handlines only catch a small percentage of each shoal and only when they are feeding, not when they are spawning. Mackerel are moderately vulnerable to fishing effort, 44% (Cheung et al 2005).
Mackerel are managed throughout their range through an international agreement called the Coastal states agreement between the EU, Norway and the Faroe Islands.
Cornish mackerel stocks have been protected by the setting up fo the mackerel box in 1980's that still prohibits industrial scale fishing for mackerel in 67,000km2 of the coast of south west England.
The minimum landing size for mackerel within Cornish waters is 20cm.
Mackerel handline fishermen are given an annual quota which is a tiny share of the overall allocated catch of the members of the coastal states agreement.
