Shearwater, tuna, dolphins, whales, orca, seagulls, marlins, sharks, and humans may hunt mackerels. Mackerels are prized (and are highly harvested) for their meat, which is often very oily. They are known for their fighting ability, and are an important recreational and commercial fishery. The meat can spoil quickly, especially in the tropics, causing scombroid food poisoning - it must be eaten on the day of capture, unless cured.

In the U.S. federal prison system, mackerel fillets are used as a standard currency among prisoners.
