Destructive fishing practices

Destructive fishing practices are practices that easily result in irreversible damage to aquatic habitats and ecosystems. Many fishing techniques can be destructive if used inappropriately, but some practices are particularly likely to result in irreversible damage. These practices are mostly, though not always, illegal. Where they are illegal, they are often inadequately enforced.

The narrowest definition of destructive fishing practices refers principally to bottom trawling over vulnerable habitat (shallow corals, deep sea corals, or seagrass, for example), as well as practices such as shark finning, blast fishing, poison fishing, muroami, and push netting. These latter practices are not significant within the fishing zones of most developed nations, being generally outlawed.

A wider and more useful definition would include:

This definition could be extended to cover activities such as:

The phrase destructive fishing practices (or DFPs) has been featured in international fisheries literature since about the 1980s. No widely accepted definition of the phrase exists, and this will almost certainly remain the situation, given very different national and industry perspectives. The DFPs discussed with the most standing are those of the Fisheries and Agriculture Organization of the United Nations - the FAO.

The Outcomes and Implementation Statements of the World Summit on Sustainable Development, held in Johannesburg in 2002, contain a commitment to phasing out destructive fishing practices in the marine environment by the year 2012. All nations attending the summit supported this statement.

Many nations had made commitments to end destructive fishing practices much earlier. In 1999, 124 nations explicitly gave their support to the FAO Code of Conduct for Responsible Fisheries 1995 through the Rome Declaration on Responsible Fisheries. The list of these nations includes most of the major fishing nations of the world. However, while the Code of Conduct contains a commitment to end destructive fishing practices, the Code contains no timelines.

Dynamite or blast fishing is done easily and cheaply with dynamite or homemade bombs made from locally available materials. Fish are killed by the shock from the blast and are then skimmed from the surface or collected from the bottom. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can damage or destroy the physical environment. Explosions are particularly harmful to coral reefs. Blast fishing is also illegal in many waterways around the world.
