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.
Climate change is modifying fish distributions [6] and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. [7] The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector.

China, by far the world’s biggest aquaculture producer, is also trying to lessen the environmental impacts of fish farming. One way: Take it offshore, where currents can deliver clean water and ...
Violent weather exacerbated by climate change fueled hunger and food insecurity across Latin America and the Caribbean in 2023, according to a new United Nations report.
This is Qatar's first offshore fish farm.It uses floating cages technology to produce 2,000 tonnes of fish annually.But its owners are hoping to double that number by expanding the project - in ...
Climate change is modifying fish distribution [25] and the productivity of marine and freshwater species. This reduces sustainable catch levels across many habitats, puts pressure on resources needed for aquaculture , on the communities that depend on fisheries, and on the oceans' ability to capture and store carbon ( biological pump ).
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. [ 68 ] A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse ...
