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.
The four dominant fish species known in the United States as Asian carp are introduced invasive species.They all cause harm within their new environments. Specifically, the four most well-known species of invasive Asian carp are black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), and bighead carp (Hypophthalmichthys nobilis).
Predatory fish such as sharks, billfish, dolphinfish and tuna form a part of the human diet and are targeted by fisheries, but they tend to concentrate significant quantities of mercury in their bodies because they are high in the food chain, especially as apex predators, due to biomagnification.

In Ohio, Spotted turtles occupy the Great Lakes region of Canada and the United States, occurring from the southern tip of Lake Michigan to the St. Lawrence River valley, as well as the upper ...
In 2024 a study [147] was released, dedicated to the impact of fishing and non fishing ships on the coastal waters of the ocean when 75% of the industrial activity occur. According to the study: "A third of fish stocks are operated beyond biologically sustainable levels and an estimated 30–50% of critical marine habitats have been lost owing ...
The largest single type of plastic pollution (~10%) and majority of large plastic in the oceans is discarded and lost nets from the fishing industry. [39] Waterborne plastic poses a serious threat to fish, seabirds, marine reptiles, and marine mammals, as well as to boats and coasts. [40]
The small shark is non-confrontational – earning its shy nickname for the way it curves and uses its tail to covers its eyes, protecting vital organs and making it harder for predators to get them.
The American paddlefish is native to the Mississippi River basin and once moved freely under the relatively unaltered conditions that existed prior to the early 1900s. It commonly inhabited large, free-flowing rivers, braided channels, backwaters, and oxbow lakes throughout the Mississippi River drainage basin, and adjacent Gulf Coast drainages.
