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.[1]

Illegal and unreported fishing contributes to the reduction in fish stocks and hurts the ability to help in recovery of the fish population. It is believed that between 10 billion and 23 billion incidences happen annually. Developing countries are more likely to be at risk for illegal activities.[2]

Although officials have tried to control the blast fishing, it is still used in impoverished pockets in the world. The effects of the blast fishing are horrifying. The water is littered with dead fish or struggling fish[3]

In Africa, poor Tanzania fishermen are using explosives to kill hundreds of fish in a matter of minutes. It is believed that the fishermen are tossing explosives into the water around 10 times per day. The major profit the fishermen are making when they take their catch to market is the likely cause for the constant dangerous practice.[4]
