Pacific mackerel

Pacific mackerel (Scomber japonicus), also widely known as chub mackerel, is a fast-swimming small pelagic species of the Scombridae family, naturally distributed across broad areas of the Pacific Ocean. It is a schooling fish found in coastal and offshore waters, often moving deeper during the day and rising toward the surface at night. Commercially, Pacific mackerel is one of the core mackerel species of the Northwest Pacific, accounting for more than 35% of total chub mackerels catch. 

From a product perspective, Pacific mackerel is valued for its moderate-oily flesh, pronounced mackerel flavor, and broad processing flexibility. It is marketed mainly for human consumption and is sold in fresh, frozen, salted, smoked, and canned forms, with strong suitability for whole round, HG, fillets, and further-processed applications. Compared with more premium Atlantic mackerel, it is positioned as a dependable and versatile alternative with strong industrial usefulness and stable consumer recognition across both domestic and export markets.

The main commercial fisheries for Pacific mackerel are concentrated in the Northwest Pacific, with China, Japan, South Korea and Taiwan forming the most important fishing and supplying countries by volume. In market terms, Pacific mackerel is best understood as a high-volume regional pelagic species with consistent relevance for frozen trade, processing, and canning rather than as a niche premium fish.
