Atlantic mackerel
Chub mackerel school like Atlantic mackerel, and their feeding habits are much the same, eating the same species of pelagic crustaceans and Sagittae that the mackerel had taken at the same time and place, while specimens taken at Woods Hole ate chiefly copepods, to a lesser extent on amphipods, salps, appendicularians, and young herring. They follow thrown bait as readily and bite quite as greedily as Atlantic mackerel do. Their breeding habits have not been studied.
