The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [67] It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change.
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.

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 ...
Zhuhai fishing port Fish being dried dockside at Pacao Harbor, Cangnan County, Zhejiang. In 1999, China set an objective of “zero growth” in coastal marine capture catch, and in 2001 changed the objective to “minus growth ". To achieve this, China has been reducing vessel numbers and relocating fishermen away from marine capture fisheries.
China's 2005 reported harvest was 32.4 million tonnes, more than 10 times that of the second-ranked nation, India, which reported 2.8 million tonnes. [2] China's 2005 reported catch of wild fish, caught in rivers, lakes, and the sea, was 17.1 million tonnes. This means that aquaculture accounts for nearly two-thirds of China's reported total ...
In response to the decimation of the species due to disease and overfishing, China began releasing juvenile F. chinensis in an effort to increase the corresponding annual catch starting in 1984. The program produced considerable results, with an average release of approximately 600 million and catch of 720 tonnes annually as of 2006.
Chinese sturgeon in Dalian Laohutan Ocean Park. Most sturgeon spawn in fresh water and migrate to salt water to mature. The Chinese sturgeon can be considered a large freshwater fish, although it spends part of its lifecycle in seawater, like the salmon, [9] except Chinese sturgeon spawn multiple times throughout their lives.
