Overfishing occurs when too many fish in a particular stock are caught and there are not enough adults to breed and sustain a healthy population. The level of overfishing has been increasing in recent decades and the number of overfished stocks is now three times higher than in 1970.
Overfishing is the practice of catching fish faster than they can replenish their population. The population remains in a constant state of decline until it is entirely decimated. Today, researchers estimate that 85% of the world’s fish resources are beyond their sustainable capacity.
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.
When defining the sustainability of fisheries, we need to know three terms: Overfished: this is sometimes termed ‘overexploited’. A fish stock with abundance below the biomass that would produce the maximum sustainable yield (MSY) is potentially considered "overfished".
7 Φεβ 2022 · Scientists have long been sounding the alarm about a looming catastrophe of ocean overfishing—the harvesting of wildlife from the sea at rates too high for species to replace themselves.
Overfishing is the main reason fish populations have declined. Overfishing means catching marine creatures faster than they can reproduce. The global proportion of overfished fisheries has steadily increased, from 10% in 1974 to 32% in 2008.
