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.
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.
The problem of overfishing are as follows: the catches of wild fish have peaked and are now in decline, rational fishery management is the exception rather than the rule, the most valuable fish is trawled to the point of extinction, the developed world is stealing from both the developing world and the future generations, and fish farming, the ...
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.

Ray Hilborn stated that the unsustainable nature of fisheries can be characterized by three aspects: . Inconsistent long-term yield refers to the imbalance in nature when fishing is practiced improperly, which results in the inability to capture the maximum sustainable yield at a regular and predictable rate.
Since 2002, China has been the world largest exporter of fish and fish products. In 2005, exports, including aquatic plants, were valued at US$7.7 billion, with Japan, the United States and the Republic of Korea as the main markets. In 2005, China was sixth largest importer of fish and fish products in the world, with imports totalling US$4.0 ...
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs.
