Essay On Overfishing

The definition of over fishing is to deplete the number of fish in a body of water by too much fishing. Overfishing is very harmful to the ecosystem, taking a species close to extinction or completely extinct. As a species gets close to extinction it can be very hard to restore them back to sustainability. Even closing the fishing game for that species is not enough for a species to comeback from overfishing. Both recreational and commercial fishing have a huge impact on overfishing, by keeping under sized fish and other aquatic life.

This is concerning for a couple of reasons. First, it has a tremendous negative impact on the marine ecosystem. Species are being taken away from ecosystems, in some cases even being depleted to near levels of extinction. For example, the same UN report reveals that, worldwide, nearly 90% of predatory fish stocks are gone [1]. That means that most of the world is losing

Sharks are much more useful when kept alive, and can be beneficial for several years; however, once they are dead there are no more benefits to be reaped besides what is originally obtained. The decrease in sharks can also be detrimental to many fisheries. Sharks feed on other carnivores down the food chain. Carnivores that sharks prey on often prey on creatures such as shellfish. Without sharks, there would be an increase in several other carnivores, leading to a vast decrease in the amount of shellfish and other herbivores in the sea, which can be detrimental to local fisheries.

The practice of shark finning should be banned worldwide. It is inhumane, promotes animal abuse, and is damaging to the marine ecosystem. as the demand for shark fin soup increased, fishermen have been trying to fulfil customers’ wishes by finning sharks. 1. Tens of millions of sharks are dying

In the eyes of society and the public, sharks are viewed as ruthless killers Millions upon millions are killed every year, and fear is a major contributor. The reality is that sharks are very complex creatures, and should be treated as such. They are an intricate part of the ocean’s ecosystem and the ecosystem would be completely thrown off without them. We need to realize that these creatures are invaluable, and that we must conserve these animals. If we do not realize this reality, we could lose sharks forever.

This initiative should be considered by all governments as soon as possible in the hopes of saving the endangered sharks. Otherwise, without sharks, the ocean biological system will be unbalanced, thus affecting the entire food chain. If the populations of planktons or other small creatures increase, consequences will follow. The control and management of the oceans will be tougher if the population of small fishes were to greatly increase. The outbreak of diseases in the ocean will be induced and this may spread to rivers and lakes which will ultimately affect us since our drinking water would become

Fishery Management: RBM and Fishery Subsidy Over fishing around the globe has lead to a dire need in effective fishery management as it has led to fisheries depleting worldwide. Seafood is one of the more popular delicacies around the world and is also the source of income for millions of fishers globally. Lack of and poor fishery management has led to an exhaust of the fish stock in the ocean, which in turn has had a negative impact on biodiversity. Poor management has also been a factor economically as it leads to a loss of about $50 billion annually for fisheries around the world. If proper steps are taken the problem can be managed, Fishery Solutions Center believes that if management is improved then abundance of fish can increase by

II. FACTORS CAUSING THE DECREASING OF OYSTER REEFS. Nowadays in many literature are represented the most important threats for oyster beds, as overharvest, development and pollution, changes in freshwater inflows, erosion from boats, diseases, invasive species, global change… (Coen et al. 2000; Seavey et al. 2011; Gregalis et al.

To control the overfishing and growing industrial fishing market, in 1977 the Canadian Government introduced a 200 mile management zone but by that time most of the ecological damage had started. However, during this time other industries like resource-extraction failed, which put pressure on the fishing industry and even the government had to encourage more catching of fish for exports. However, as stocks of cod fish continued to drastically decline the government finally decided to ban cod fishing in 1992. Though the cod fishing industry boosted the Canadian economy and provided employment for local

Overfishing happens because fish are captured faster than they can reproduce. With the oceans covering more than 70% of the Earth the health of the marine life is essential for the humans and many other organisms to survive. Each time a boat goes out fishing, the boat on average waste 90% of all the fish they have caught, according to ted.com, this is just one example of overfishing. This means that 90% of the fish are caught but not used for food and they are just thrown out. Wasting fish affects the biodiversity in the oceans since it puts extinction the species to risc, this affects the food
