Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
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 ...
Oceana's main focus with sustainable fishing is providing clean, plentiful food. They often cite the lack of emissions or resources, like land or fresh water, that wild fish require, and that this lack of pollution or resources would be necessary to feed the world's growing population. [14] This campaign is called "Save the Oceans, Feed the World".
Overfishing of sharks has increased as the global demand has skyrocketed in recent years. Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth.
PORTLAND, Maine (AP) — The number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said.
The release of nitrogen oxides (N 2 O, NO) from anthropogenic activities and oxygen-depleted zones causes stratospheric ozone depletion leading to higher UVB exposition, which produces the damage of marine life, acid rain and ocean warming. Ocean warming causes water stratification, deoxygenation, and the formation of dead zones.

But this is still sustainable fishing, which could continue indefinitely at its reduced stock numbers and yield. There is a wide range of escapement sizes that present no threat that the stock might collapse or that the stock structure might erode. [2] On the other hand, overfishing can precede severe stock depletion and fishery collapse. [15]
