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 ...
Blast fishing, fish bombing, dynamite fishing or grenade fishing is a destructive fishing practice using explosives to stun or kill schools of fish for easy collection. This often illegal practice is extremely destructive to the surrounding ecosystem , as the explosion often destroys the underlying habitat (such as coral reefs ) that supports ...

[1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...

It said that on the Scotian Shelf after the cod were gone, the small plankton-eating fish (capelin, etc.) that the cod had eaten multiplied to many times their old numbers and ate cod eggs and cod hatchlings.

Environmental crises are for many people an abstraction, and so can seem their repercussions. But I am a physician in infectious diseases, and my first instinct when looking at a forest is to see ...
In 2024 a study [147] was released, dedicated to the impact of fishing and non fishing ships on the coastal waters of the ocean when 75% of the industrial activity occur. According to the study: "A third of fish stocks are operated beyond biologically sustainable levels and an estimated 30–50% of critical marine habitats have been lost owing ...
