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 ]
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.
Over-fishing exacerbates the effects of climate change by creating conditions that make a fishing population more sensitive to environmental changes. Studies show that the state of the ocean is causing fisheries to collapse, and in areas where fisheries have not yet collapsed, the amount of over-fishing that is done is having a significant ...
[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]
China has upset many countries in the Asia-Pacific region with its release of a new official map that lays claim to most of the South China Sea, as well as to contested parts of India and Russia ...
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]

Social factors, through social conception of human well-being, can potentially improve the implementation of fisheries regulation and governance. [42] This remains a difficult concept in developing fishery regions, such as Caribbean coral reef fisheries, where managing and regulating parrotfish ( Sparisoma viride ) resulted in an initial ...
