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.
Overfishing can be sustainable. [dubious – discuss] According to Hilborn, overfishing can be "a misallocation of societies' resources", but it does not necessarily threaten conservation or sustainability". [2] Overfishing is traditionally defined as harvesting so many fish that the yield is less than it would be if fishing were reduced. [2]
The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.
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]
Texas has the dubious distinction of leading the nation in polluted waterways. A new report draws upon self disclosed data by industrial facilities provided to the EPA. The study counted 17 ...
Texas' water infrastructure, such as dams, pipelines, and reservoirs, is aging and often not equipped to handle modern water management challenges. Leakage and inefficiencies exacerbate the problem.
A 2019 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report found that overfishing is the main driver of mass species extinction in oceans. [142] [143] Overfishing has reduced fish and marine mammal biomass by 60% since the 1800s. [144] It is currently pushing over one-third of sharks and rays toward ...
