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 ...
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 ...
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]
With the absence of foreign fishing, many Canadian and U.S fishing trawlers took their place, and the number of cod kept diminishing past a point of recovery. [12] Many local fishers noticed the drastic decrease of cod and tried to inform local government officials. [citation needed] In a 1978 white paper, the Newfoundland government stated: [15]
Illegal, Unreported, and Unregulated (IUU) Fishing poses a global challenge and has significant economic and environmental repercussions. [5] The impact of IUU fishing includes economic losses, job losses, scarcity, price distortion, food insecurity and unfair competition, [6] together with the depletion of fish populations and damages to the marine habitat.

Territorial Use Rights for Fishing (TURF) programs are a unique type of fishery law applicable for small scale fisheries. These community based programs allocate area based fishing privileges to groups or individuals with the goal of preventing overexploitation and unsustainable fishing.
The focus of sustainable fishing is often on the fish. Other factors are sometimes included in the broader question of sustainability. The use of non-renewable resources is not fully sustainable. This might include diesel fuel for the fishing ships and boats: there is even a debate about the long term sustainability of biofuels.
LME-based conservation is based on recognition that the world's coastal ocean waters are degraded by unsustainable fishing practices, habitat degradation, eutrophication, toxic pollution, aerosol contamination, and emerging diseases, and that positive actions to mitigate these threats require coordinated actions by governments and civil society ...
