The results not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life.
Additionally, ghost fishing is a major threat due to capture fisheries. Cutting back on fishery activities will make it possible for fish to breed and produce young ones and this cycle would continue until we have a healthy supply of seafood available again.
Story of Hope Forward-Thinking Management Can Maintain Fishery Productivity Pacific salmon in Alaska are among the most intensively managed species in the world, with excellent monitoring of fish populations and the fishery itself. Temperate and high latitude, and tropical areas, ranked intermediate with mean psust values of The fishermen would make a beeline to the goals, catch the fish around them, and say the scientists do not know what they are talking about.
It has reached a point where recovery may be impossible. Received Sep 11; Accepted Nov 7. Fish inadvertently get caught in these nets and die inside the oceans. Human beings capture fish for food. Sustainable seafood Sustainable seafood is a movement that has gained momentum as more people become aware of overfishing and environmentally destructive fishing methods.
For example, herring is a vital prey species for the cod. For example, seabirds such puffins were dependent on the sandeel for their food around the Shetland Islands.
Extinction of any living species on the earth causes and imbalance and has a huge impact on the ecosystem. Impact of Overfishing Bycatch found in gillnets. The following list gives the names of some of the species of fish have been put under danger of extinction due to overfishing.

Because fishing has long been an industry used by humans, there are a number of reasons why it is a problem today. While industrial fishing is often effectively controlled, smaller scale and recreational fishermen can often break regulations such as bag limits and seasonal closures.
This is due largely to sound scientific management by state and federal agencies.Overfishing—catching fish faster than they can reproduce—is an urgent issue and is one of the biggest threats to ocean ecosystems.
Today, roughly one-third of assessed fish populations are over-fished and over half are fully-fished (FAO ).
Overfishing can wreak havoc and destroy the environment and marine ecology and completely disrupt the food chain. For example, herring is a vital prey species for the cod. Therefore, when herring are overfished the cod population suffers as well.
Overfishing is also closely tied to bycatch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and cetaceans.
DECREASED FOOD SECURITY Coastal communities around the world depend on fish as their primary source of protein. Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish in time, resulting in those species either becoming depleted or very underpopulated in that given area.
Overfishing has spread all over the globe and has been present for centuries. Despite some limitations, L index allows for a robust evaluation of the risks of marine ecosystems to overfishing and illustrates when and where fishing became unsustainable at the ecosystem level since the s.
Scientists believe that the hazard to the marine ecosystem by overfishing is cause for more concern than other obvious threats like environmental pollution. Risk to the marine biodiversity Unsustainable and unchecked fishing practices have driven many fish stocks to the verge of collapse.Download
