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 ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
But FADs are controversial as they catch tuna juveniles before they have had the chance to breed, leading to overfishing, as well as endangered, threatened and protected species.
Tuna accumulate more mercury over time because they are high up the food chain, eating smaller fish frequently. But the canning process means that mercury concentration is doubled or tripled ...

Miongo explained that warming waters due to climate change forced tuna species to alter their migration patterns, making it harder for local fishers to catch them. Tuna catch dries up for Kenya's ...
