Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Fisheries-induced evolution ( FIE) is the microevolution of an exploited aquatic organism's population, brought on through the artificial selection for biological traits by fishing practices ( fishing techniques and fisheries management ). [1] Fishing, of any severity or effort, will impose an additional layer of mortality to the natural ...
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 couple of "magnet fishing" enthusiasts say they pulled up a safe containing an estimated $100,000 (£78,000) from a New York lake. James Kane and Barbie Agostini threw a rope with a magnet into ...
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 which is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ecosystems within the ocean ...
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
Those are the three phases of a journey aboard a seaglider, a new type of fully electric boat-plane hybrid that could become a mainstay of coastal communities the world over, according to its ...
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.
