Mackerel stocks 'near breaking point' due to overfishing, conservationists warn

Conservationists called for countries to work together to develop a strategy that leads to the recovery of the mackerel stock.

Mackerel is under immense pressure from overfishing, conservationists have warned, as they lowered its rating in the latest sustainable fish guide.

Britain's Marine Conservation Society (MCS) has updated its Good Fish Guide, which uses a traffic light system for consumers, along with a one to five scale for businesses, to highlight seafood which is sustainable to eat.
