Essay On Overfishing

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. Not only do fish have to worry about fishermen but they also have to worry about each other, fish deplete their own population by feeding on one another. For example, Betta fish are known to eat fish of the same species but can live peacefully with fish of another species.

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

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. Fishermen hunt sharks in order to sell their meat for money, however, those sharks are crucial to the survival of other desirable marine life such as shellfish, which fishermen also fish.

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.

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;

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

The lecturer and the reading passage offer two theories to explain why the sea otter population is in rapid decline. The two theories are predation theory and pollution theory. The professor argues predation is the more likely cause than pollution because of the absence of dead sea otters washing up on shores. However, the reading passage attributes the decline of the sea otters population based on evidence of increased ocean contaminates leading to greater vulnerability to infections.

Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.

In today 's modern world as we expand, we are taking away habitats from animals and other diverse ecosystems. By doing this we are causes animals to become endangered and extinct. One animal that is harmed by the expansion of humans is the manatee. The manatee lives in warm shallow water next the the shore because that is where the animals have access to food and other resources.

The Laysan Albatross is an incredible creature, from being able to stay with one mate their entire life to having a ten-foot wingspan. People need to become aware that this unique bird is now endangered. This is the result of large amounts of plastics on our beaches and oceans, along with overfishing and natural and introduced predators. (SOMEONE ELABORATE) nah
