Explanation

Herring is the dominant pelagic fish in the North Sea ecosystem. The North Sea herring fishery has been commercially crucial for centuries, supporting the UK's fishing industry. Cod, halibut, and mackerel are also present, but herring biomass has historically been highest. Pelagic fish live in the water column (not near bottom), and herring form massive schools.
