There are a number of communities around the world that rely on fish as their primary resource for food. The problem is unfortunately so widespread that effects can be felt in every part of the world. While this is poised to have long-term effects on human consumption, there are also a number of other effects, such as: For example, cod off the coast of Canada on the Atlantic seaboard have been over fished to devastating consequences for the fishing community there.
Namely, there are insufficient fishing regulations in the high seas. Economic Needs High demand for fish for economic needs have pulled up the fishing efforts to a higher place.
Modern day technology and hi-tech equipments have made it easy to catch a larger number of fish in a shorter span of time and with minimal effort. All over the world, many fishing industries have huge vessels, equipment and technology that they can deploy deep into the oceans.
Poor fisheries management Fisheries rules and regulations are not assertive enough to limit fishing capacity to a sustainable level. If caught, they are normally destroyed and discarded either in the water or ashore.
And I am sure that most of you can relate to that picture. The animals may include protected or endangered species or species that are of little or no economic value.
Without the ability to catch their food, their populations are threatened. They even set catch limits above the recommended maximum amount. In commercial fishing huge nets are deployed into the water that are dragged along the sea floor trawling.
With increased overfishing related practices and without sustainable management, many fish stocks are reduced to below acceptable levels. In the case of overexploited stocks, which are in particular need of recovery, this price may even exceed the market price obtained for the landed fish.
Many modern boats seek opportunities through high capability of catching more fish in an easier way. The environment department has already placed regulations on the size of fish that fishermen are allowed to catch, you can see it below: The world is a global community with a growing population and an appetite for fish from around the planet.
The volume of the catch that can be sustained over an indefinite period depends on the size of the stock.
Watch the video here: This means that areas can be harmed or depleted. This campaign is aimed at putting an end to the commercial fishing of these billfish species. This is one of the main reasons that fishermen have to travel longer distances deeper into the sea to catch fish.
Fishing costs are the second major economic variable in a given fishery. The white arrows show the route taken by the fish from the sea to the consumer. In controlled amounts, algae is essential to helping marine life thrive, but if it is allowed to grow at will, it can impact fish, reefs, and more, leading to serious destruction.
The volume of the catch that can be sustained over an indefinite period depends on the size of the stock. Causes of Overfishing Put simply, overfishing occurs when more fish are caught then are able to reproduce to repopulate.
Coral health becomes compromised as well.
Invertebrates such as crabs, starfish, brittle stars, sea urchins, sponges, mollusks, and warms could also be caught, destroyed, and thrown back into the sea.
This ends up affecting the rest of the ecosystemwith issues such as the increased growth of algae.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. Overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences.
Overfishing has risen to such an extent that many of the fish species have either become extinct or are at the verge of extinction. Since many of us are not fully aware of what overfishing is, what are the reasons that lead to overfishing and its impacts on the ecosystem; we are going to tell you what exactly is happening around the world.
Causes of Overfishing. There are numerous reasons for overfishing. The major ones include: 1. Poor Fisheries Management. The fishing industry has long been weighed down by a lack of management oversight and proper government regulations.
Traceability of fishing. The causes of overfishing can be placed into these three categories: Overcapacity: All over the world, many fishing industries have huge vessels, equipment and technology that they can deploy deep into the. The causes of overfishing > It is now generally understood when and why fish stocks become depleted.
Global demand for fish and the intensity of fishing activity are known to be key factors in this context, but ecological aspects also play an important role.Download
