Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate that is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...
Most of the blast fishing is however done in the south, near Palawan and the South China Sea. [28] A study conducted in 2002 reported that destructive fishing methods had caused the degradation of about 70% of Philippine coral reefs and reduced annual fisheries production by about 177,500 metric tons in the 1990s.

Bottom trawling uses nets that can be as large as a football field that can damage marine habitats, campaigners say.
In the last 18 months, the South West Deeps experienced almost 19,000 hours of industrial fishing, 3,370 hours of which was bottom-trawling, according to Global Fishing Watch data.
These practices are destructive because they impact the habitat that the reef fish live on after the fish have been removed. Bottom trawling, the practice of pulling a fishing net along the sea bottom behind trawlers, removes around 5 to 25% of an area's seabed life on a single run. [12] This method of fishing tends to cause a lot of bycatch. [11]
Among the major fishing techniques bottom trawling is a destructive one. Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs ( shellfish , squid , octopus ) and edible marine invertebrates .
Reef net fishing is considered one of the most sustainable fish-catching methods, resulting in minimal bycatch. On the reef net, any non-target fish are tossed back into the water, resulting in ...
