The mackerel is a fast-swimming, pelagic fish found in temperate and tropical seas across the globe. This highly migratory species forms large schools in the upper layers of the ocean, making it a target for both commercial fisheries and recreational anglers. Understanding where mackerel are found requires looking at specific oceanic regions, water temperatures, and seasonal movements.
Global Distribution by Ocean
Mackerel species inhabit several distinct bodies of water around the world. Their presence is largely dependent on water temperature, generally preferring temperatures between 6 and 20 degrees Celsius. While specific species have unique ranges, the fish is generally abundant in the North Atlantic, the North Pacific, and the Mediterranean Sea. The distribution is largely influenced by ocean currents and the availability of smaller fish and crustaceans, which constitute their primary diet.
North Atlantic Populations
In the North Atlantic, mackerel is extremely prevalent, forming the basis of a significant fishing industry. The populations here are typically divided into distinct stocks based on spawning grounds. You will find large concentrations in the waters around the British Isles, Norway, and the Faroe Islands. The fish also migrate along the coast of Iceland and down the eastern seaboard of North America, from Canada to the southern United States.

Coastal waters of Iceland
Gulf of Maine and Georges Bank
North Pacific and Asian Waters
The North Pacific region hosts some of the most active mackerel fisheries in the world. Japanese waters, particularly near Hokkaido, are famous for the fish, where it is a staple in the local diet. The species also thrives in the Bering Sea and the coastal waters of South Korea and China. These populations are closely monitored due to their economic importance and migratory nature.
Southern Hemisphere and Tropical Zones
While often associated with cooler waters, mackerel is also found in the Southern Hemisphere and tropical regions. In the South Atlantic, the species is caught off the coasts of South Africa and Argentina. In the tropical Indo-Pacific, Spanish mackerel and related species are common. These fish often inhabit coastal waters, estuaries, and even the surf zone, bringing them closer to shore than their cold-water cousins.
Seasonal Movements and Migration
One of the most defining characteristics of mackerel is its constant movement. The fish undertake seasonal migrations for feeding and spawning. During the summer months, populations often move toward the poles to feed in the nutrient-rich waters. As winter approaches and temperatures drop, they migrate to warmer, deeper waters to conserve energy. This migration means that where the fish is found changes dramatically throughout the year.
Commercial and Recreational Fisheries
Due to their abundance and oil-rich flesh, mackerel is a major target for commercial fishing fleets. Countries with active fisheries include the United Kingdom, Norway, Russia, Japan, and Chile. Recreational anglers also seek this fish due to its aggressive strikes and fast runs. Anglers typically locate schools by looking on the edges of currents, temperature breaks, or near structures like reefs and pinnacles that force the fish to surface.
