The invasive freshwater zebra mussels, native to the Black, Caspian, and Azov seas, were probably transported to the Great Lakes via ballast water from a transoceanic vessel. [21] Meinesz believes that one of the worst cases of a single invasive species causing harm to an ecosystem can be attributed to a seemingly harmless jellyfish .
According to a United Nations Environment Program report, the Caribbean coral reefs might face extirpation in next 20 years due to population expansion along the coast lines, overfishing, the pollution of coastal areas, global warming, and invasive species. [124] In 2005, the Caribbean lost about 50% of its reef in one year due to coral bleaching.
The number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said. The National Oceanic and Atmospheric Administration ...
Wild fisheries exist primarily in the oceans, and particularly around coasts and continental shelves, but also exist in lakes and rivers. Issues with wild fisheries are overfishing and pollution. Significant wild fisheries have collapsed or are in danger of collapsing, due to overfishing and pollution.
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.
A town on northern Mexico’s Pacific coast saw its beaches carpeted with dead fish after what experts describe as a toxic algae bloom. Officials in the northern state of Sinaloa said this week ...

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.
