Mackerel

Mackerel is a fish gregarious, that is, they live and migrate in large schools. This behaviour not only provides them with safety from predators, but also makes it easier for them to feed. During warmer seasons, mackerel actively feed on plankton, eggs of other fish and small crustaceans. When they reach sexual maturity, they become predatory and consume smaller fish such as sardines and anchovies.

In addition, mackerel show a marked migratory behaviour. In spring, they return to warmer, near-shore waters to reproduce. Between May and July, females lay eggs 200,000 and 400,000 eggs in open waters, which hatch in a few days.
