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.
[100] [101] According to the IPCC 2019 Special Report on the Ocean and Cryosphere in a Changing Climate, the viability of species is being disrupted throughout the ocean food web due to changes in ocean chemistry. As the ocean warms, mixing between water layers decreases, resulting in less oxygen and nutrients being available for marine life. [102]
Overfishing (2006 Pilot Environmental Performance Index) Although there is a decline of fisheries due to climate change, a related cause for this decrease is due to over-fishing. [ 58 ] Over-fishing exacerbates the effects of climate change by creating conditions that make a fishing population more sensitive to environmental changes.
Historically, this anadromous fish was found in China, Japan, and the Korean Peninsula, but it has been extirpated from Korea, Japan, and most regions in China due to habitat loss and overfishing. [1] It is strictly protected by the Chinese government, named a "national treasure" much like its mammalian counterpart, the giant panda.

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]
China appears to be closing surveillance gaps in the South China Sea with the construction of a new radar said to have counter-stealth capabilities on Triton Island, new satellite images show.
Due to overfishing, pollution, global temperature increase, and change in pH to the world's oceans, the South China Sea is suffering from a lack in biodiversity among marine life. [30] Historically, China was the world's largest capture fisheries and aquaculture producer, making the fish market a significant part of the Chinese economy. [ 39 ]
