This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
There are many alternatives to overfishing that will help control the population. 1. With a better management system, more referred to as fishing rights, people can reverse the reasons that prime to overfishing. With fishing rights in effect, commercial fishermen benefits are projected to the long-term well-being of the fishery. Their yearly intake improves also the fish population
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
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
Luther King says in "9 Interesting Facts and Statistics about Littering", 1.9 billion tons of litter end up in the ocean. The ocean is another ecosystem made up of many diverse animals and plants. In “ 5 Ways Pollution Is Killing Animals”, Abigail Geer tells us that there are many things that can pollute the water ranging from noise, chemical and acid runoff, waste water and oils. All of these types of pollutions are affecting the marine life drastically. Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction.
Lake Michigan is home to very diverse populations and species. The introduction of Asian carp into the Great Lakes has had an adverse effect on native fish and could jeopardize the fishing industry, particularly lake perch and trout populations. The Asian carp eat many tiny plants and animals, which are food for many native fish. This will eventually affect the population and growth of the Great Lakes native fish. The Asian carp should be removed from the Great Lakes as shown in the following paragraphs.
mainly talked about the Illegal, Unreported and Unregulated (IUU) fishing both in US domestic waters as well as high seas. IUU fishing impacts sustainable global fisheries, food security, marine ecosystems, and conservation and management measures that protect marine resources. According to NOAA, IUU fishing significantly affects multi-billion dollar US fisheries industry. Therefore, I think the speaker is addressing an important issue. I learned a bunch of new things from this presentation.
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al.
The main species being killed are the Bottlenose Dolphins, Spotted Dolphins, Risso’s Dolphins, False Killer Whales, and Short-Finned Pilot Whales. All of those species listed are considered threatened by IUCN-World Conservation Union. If these species were to become extinct or endangered there would be an overpopulation of fish in the oceans (Conservationists). In many ways, the Japanese businesses doing these drive hunts are causing many different problems the environment that will eventually come back to haunt the
Sharks have the task of killing the wounded, old, and sick fish in schools to keep the stocks of fish healthy and plentiful. 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.
Beaches, docks, and other shallow, oxygen-rich areas provide a suitable habitat for the clams. Because of this, Asian clams greatly impact swimming areas since their sharp shells can cause injuries among swimmers. Also located in shallow areas of lakes, typically, are water intake systems, which Asian clams also have the tendency to clog and ultimately destroy. Since the town of Lake George 's main drinking water source is the lake, this creates a huge issue. The clams also clog water intake systems in private boats and homes, costing owners hundreds of dollars to fix.
The stakeholders in this issue are environmental groups, such as Greenpeace, who firstly advocated for the ban on commercially fishing Pollock in Alaska, as well as the Federal government, who passed the legislature. Their actions have directly led to the endangerment of the Western stock stellar sea lion. Fortunately, they are also the precise people who can remedy the situation. Should my plan of action, the reintroduction of commercial fishing of Western stock Pollock, be effective, the stellar sea lions could achieve their carrying capacity once more. The herring population would grow exponentially, which in turn would cause a major growth in sea lion population.
Finally, changes in environmental conditions are also responsible for the collapse of the East Coast Fishery. Water temperatures have dropped and ocean salinity levels have changed, causing fish to change their migratory routes, and avoid areas that are changing. People have suggested that the increase in the seal population has reduced the amount of fish because greater quantities of seals eat greater quantities of fish. In conclusion, a number of theories such as, overfishing, destructive fishing practices, and changes in natural conditions explain why the East Coast Fishery has
