Unsustainable fishing methods

Unsustainable fishing methods are ways of catching wild fish that are not considered sustainable in the long term. This could be because they threaten the fish stock itself by overfishing, or because they threaten the environment the fish need to thrive. Dynamite fishing, electro-fishing, or fishing with poisons are examples of the latter, used in developing countries.

Western unsustainable fishing methods include bottom trawling, which was called a 'great harm' by a group of leading marine environmentalists.
