Pacific Chub Mackerel

Also known as Chub Mackerel, Pacific Mackerel, Greenback Mackerel

Pacific chub mackerel form dense, coordinated schools that constantly cruise coastal and offshore waters in search of plankton and small schooling fish. These torpedo-shaped swimmers rely on continuous motion to ventilate their gills and maintain buoyancy. Serving as a foundational forage fish, they sustain marine food webs across the Pacific and Indian oceans while supporting massive commercial purse-seine fisheries.
