For centuries, mankind has harvested abundant fish and relied on the ocean to survive. In recent years, new technologies have enabled humans to capture fish from the sea on a large scale and provide food for the fastest growing population on the planet. Unfortunately, these practices have had many negative environmental impacts, and over fishing is considered to be the main cause of ecosystem damage in many aquatic systems.
The Impacts Of Fishing
Over-fishing
One of the main consequences of industrial fishing is that some species are almost extinct. Perhaps the most famous example is the Atlantic salmon. 17th-century people said that the northwest Atlantic has many corals that can go to the sea. Catfish fishing is the basis of the New England economy. Many people ride on their kayaks under 1000 and use their fishing rods for a living. In the 1960s, new technologies like radar and sonar were deeper than fishermen.
Over the next few decades, large-eg landings began to increase sharply, but in the 1990s the fishery shrank rapidly. Other than Newfoundland, the world’s largest salmon fishery, salmon biomass is estimated to have declined by over 99%. Six other Canadian coastal resources have reduced biomass by more than 75%. 2 The number of fish is so small that Canada can suspend salmon fishing to restore resources. Reduce the time people catch and the total amount of salmon they catch.
Habitat Destruction
In addition to removing more and more fish from the sea, many industrial fishing methods destroy aquatic habitats. Dr is a common way of harvesting cockroaches, and large metal shovels are used at the bottom of the shore to collect cockroaches. This process cools the seabed sediment and hangs the water column, reducing the water quality. This practice also allows insects in caves to be excavated from sediment.
Solution
The impact of fisheries in recent years has become a source of more and more research interest. Much of this is due to the collapse of commercially valuable fishing and the endangered number of animals. Some species, such as the Mid-Atlantic Salmon and flo, have restricted fishing to successfully restore depleted resources. However, for other species, such as Atlantic salmon, this regulation did not cause population recovery. In this example, there may be other factors, such as an increase in water temperature that prevents recovery.
