Brief Summary
provided by Ecomare
Most people are familiar with mackerel from the fish store, and particularly as a smoked fish. Live mackerel are rapid predator fish and eat mainly zooplankton. In the summer months, they swim in large schools in the upper water column, hunting copepods, fish larvae and other such organisms. After spawning in the summer, they also hunt herring, sprat and lesser sandeel, bringing them closer to the coast. There have been reports of schools of mackerel 9 by 4 kilometers in size and 40 meters deep.
