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.
[49] [50] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of internal ocean temperature". [51] Marine organisms are moving to cooler parts of the ocean as global warming proceeds.
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate that is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...

The sea animal's aquatic ecosystem may also collapse due to the destruction of the food chain. Additionally, ghost fishing is a major threat due to capture fisheries. [16] Ghost fishing occurs when a net, such as a gill net or trawl, is lost or discarded at sea and drifts within the oceans, and can still act to capture marine organisms. [16]
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 ...
