Atlantic MackerelAtlantic mackerel are a species of mackerel found in the western Atlantic Ocean. They are a small to medium-sized fish, growing to a length of around 60 cm (24 in). The body is blue-green or olive above, with a silvery flanks and belly. There are dark spots on the upper body and fins. The first dorsal fin has 13-15 spines and the second dorsal fin has 18-20 soft rays. The pectoral fins are relatively long, with 17-19 rays each. The anal fin has 19-21 soft rays.
The Atlantic mackerel is a pelagic fish found in the temperate waters of the North Atlantic. It is an important food fish and is also used in aquaculture. The Atlantic mackerel is a fast-swimming fish and can reach speeds of up to 18 mph (29 km/h). It has a streamlined body and a long, forked tail. The body is blue-green or greenish-blue on the back, with a silver-white underside. The fish has two dorsal fins, the first of which is shorter than the second.
The Atlantic mackerel is found in the temperate waters of the North Atlantic, from Newfoundland to Morocco. It is also found in the Mediterranean Sea and the Black Sea. The fish is an important food fish and is also used in aquaculture. In 2012, the global production of Atlantic mackerel was 1.1 million tonnes, with a value of US$2.2 billion. The majority of the fish are caught in the Northeast Atlantic, with around 500,000 tonnes caught in 2013. The main fishing nations are Norway, the Faroe Islands, Iceland, and the United Kingdom.

The body is blue-green or greenish-blue on the back, with a silver-white underside. The fish has two dorsal fins, the first of which is shorter than the second. Mackerel are found in the offshore waters of the western Atlantic, from Newfoundland to Florida.
They are also found in the Gulf of Mexico and the Caribbean Sea. Spawning takes place from May to August, in offshore waters at depths of around 200 m (660 ft). The eggs float freely in the water column and hatch after around 24 hours. The larvae are planktonic, growing to a length of around 5 cm (2 in) after around two months. They then transition to a benthic lifestyle, settling on the seabed at depths of around 50 m (160 ft).
Mackerel are predators, feeding on smaller fish and squid. They are an important food source for larger predatory fish such as tuna, sharks, and billfish. They are also commercially important, with fisheries in North America, Europe, and Japan. The flesh of mackerel is rich in omega-3 fatty acids and is considered to be healthy for human consumption.
Global atlantic mackerel production
Atlantic mackerel is one of the most important fish species in global commercial fisheries. In 2016, the total global production of Atlantic mackerel was 990,977 metric tons. The top five producing countries were China (210,856 metric tons), Norway (103,365 metric tons), Iceland (93,974 metric tons), the United Kingdom (68,944 metric tons), and Canada (43,844 metric tons).
The Atlantic mackerel fishery is an important source of income and employment for coastal communities around the world. In 2016, the total global value of the Atlantic mackerel fishery was $1.3 billion. The top five producing countries were China ($333 million), Iceland ($273 million), Norway ($212 million), the United Kingdom ($183 million), and Canada ($142 million). Mackerel is a popular seafood item and is consumed fresh, frozen, canned, smoked, and salted. It is a rich source of omega-3 fatty acids, protein, and vitamins A and B12.
The Atlantic mackerel fishery is managed by regional fisheries management organizations. The International Commission for the Conservation of Atlantic Tunas (ICCAT) is responsible for the conservation of tunas and tuna-like species in the Atlantic Ocean. ICCAT has implemented a number of measures to ensure the sustainable use of Atlantic mackerel, including setting catch limits and regulating the fishing gear used.
The future of the Atlantic mackerel fishery is uncertain due to the changing climate. The northward shift of the Gulf Stream is causing ocean temperatures to rise in the North Atlantic, which is affecting the distribution and abundance of Atlantic mackerel. As a result, the Atlantic mackerel fishery is likely to face challenges in the future.
