Water Contaminants Are Bad For The Marine Life And The Environment

Factors on the collapse of the West Coast fishery•Overfishing•Changes in the Environment/Global Warming•Different agreements/lack of treatiesOverfishingIn the 90's there was an 800,000 tonnes catch per year for salmon. Instead of being over 100 major fish processing plants in British Colombia, there's fewer than 10.Changes in the Environment/Global WarmingThe Pacific Ocean is increasing in temperature due to Global Warming, which there's a possibility of threatening the salmon's habitat. The preferable temperature for salmon is below 7 degrees, so if the water temperatures keep rising, the salmon will move towards the Bering sea because its cooler. Instead of the spawning occurring in British Colombia, it will be in

For over one hundred years the salmon population in the Columbia Basin has been drastically decreasing, due to overfishing and man made obstacles. The Columbia Basin Fish Accords have given a one billion dollar grant to tribes and states for habitat restoration projects. However, the conflict still rages between the native tribes of the area, and the federal government whose roadblocks such as dams prohibit the free flowing rivers that bring salmon back to the spawning grounds. The effort to keep salmon coming back up the river while keeping the dams intact is the struggle that the federal grant hopes to solve.

There are numerous regulations in place to protect the Delta Smelt. These regulations basically give the state government and the environmentalists the power to do whatever they see fit to protect the Delta Smelt. And a large portion of what they feel needs to be done comes down to where the water will go. The biggest law they use to support their policies is the Endangered Species Act, under which the Delta Smelt have protected status. They use the clout from these laws to do things like, pump 1.4 trillion gallons of water from the Delta out into the San Francisco Bay for reproductive proposes for the Delta Smelt. While they have put these laws in place and used them to their fullest extent, it is not working. All this trouble has not come even close to saving, or even protecting, the Delta Smelt. Biologists recently caught the lowest number of Delta Smelt ever recorded in a count. They caught six. Not even five years ago, they were catching hundreds in one netting. While the actual population size isn’t known, it is safe to assume the Delta Smelt are on the verge of extinction, and that’s with over-barring, unconstitutional restrictions to prevent exactly this outcome.

Commercial fishing in New England is not sustainable. Commercial fishing is the catching of fish for profit and, as with other profit making activities, there are trade-offs between a pure capitalistic market and the damage it does to resources. For commercial fishing, this trade-off is that the more fish the fishermen catch, the more damage it does to the fish population. To make commercial fishing sustainable, large regulations need to be in place, as Jack said. However, large regulations of a free market are usually not accepted in America and would not be put in place in time to save the fish and sustain commercial fishing.

One of the many problems the severe water drought has caused has affected many of the animals such as the American river fish, salmon, and steelheads. In the Sacramento Bee the article “Drought Threatens American River Fish” by Matt Weiser explains how the steelhead are threatened species who are about to hatch in the American River, but due to the drought the sunny temperature and the

While it is not entirely known how salmon manage to navigate treacherous waters to return to the place they are born, research shows that changes in the water have affected the way they perceive the world around them, and could greatly impact the way that salmon

Overfishing, dams, and pollution, are the main causes of the decrease in number of this species. Pollution is one of the causes of their endangerment because it causes the fish to get sick and develop deformities. Sturgeon are vulnerable to low oxygen levels. Low oxygen is caused by pollution and algae that

The life cycle of the Atlantic salmon begins in late October when rivers are just cool enough to begin production of the new salmon. The female starts by digging a small nest called a redd in the bottom gravel area of a stream. Reddd’s are built in a way that allows a clean flow and plenty of oxygen to be received by the growing fish. The male salmon then projects their milt (sperm) onto the redd to fertilize the egg. With swift movements made by the tail gravel is projected

It provides many things for Alaskan natives such as: money, jobs, entertainment, and food. Destroying the salmon habitat would eliminate jobs and a source of income for numerous amounts of people. Not only is it providing jobs for the population, but it is also clearly important to them. As shown in the video, one woman had been fishing salmon since she was a little girl. It has been tradition for her and she has never known anything else. I’m sure she has been raised fishing salmon, and she would like to continue that in her family as they get older. I would assume that if fishing was part of my tradition, I too, would want to see one of the largest salmon breeding grounds in the world carry on. Finally, it’s also an important food source for the Alaskan people and they can sustainably fish as much as they want to yet still feed their

A fish once know for it’s amazing ability to clean ponds and be an almost limitless form of food have since longed turned against us. They now threaten our waterways, native species, and even people. I am of course talking about the invaders from the east, known as the Asian Carp. This fish alone has been able to change the ecosystem and out eat, out number, and destroy native waterways. And they will continue to do irreversible damage to the United States waterways.

Nonetheless, wild pacific salmon are fished near the shore or the ocean between May and September because they spawn in their river habitats during these months. The other challenge was that wild pacific salmon were depleting and protecting them was a great challenge as it was indirectly posing a threat to Walmart and its sea food supply chain.

The triple bottom line of fishing is influenced by sustainability in many ways. One way is the demand for fish increases with population. As well there are new laws limiting fishing, ultimately forcing once

I am writing this letter to discuss a few thoughts, which I have concerning marine pollution happening currently in the southern part of the country in the lower delta region to be precise. This is as a result of consistent oil spillage occurring in and around the Niger delta area. I have come to learn that this issue has worsened over the past ten years and has begun causing problems for the neighboring communities. As I am currently enrolled in an oceanography course in my university, I have come to understand some of the adverse effects which introduction of oil into marine environments can pose. On closer study, I have reduced this effects to direct manipulation on marine life which further more affects humans who depend on these water bodies as their main source of livelihood. With this letter I am hoping to draw some attention to the current crisis and seek a restorative response from the government. This sort of positive response will ensure that the future of marine development in the area returns to former yields thereby benefiting the occupants of nearby villagers and better supporting their economies.

Marine pollution is defined by the European Environmental Agency as "Direct or indirect introduction by humans of substances or energy into the marine environment (including estuaries), resulting in harm to living resources, hazards to human health, hindrances to marine activities including fishing, impairment of the quality of sea water and reduction of amenities" (Marine pollution-EEA, 2006). This is the same definition, with some slight rewording, as that developed by the United Nations. It is all-encompassing and indicates the extent and seriousness of the problem.

I make my way down the sand with the scorching sun shining bright in my face, trying to reach to the cooling ocean as fast as I can. I feel the ocean’s continuous movement of the currents shifting back and forth, making me think about how the ocean currents create the rubbish patches, gathering bits of plastic on the way. I wonder if people think about the consequences of littering before doing it and the harm that it has on the sea life?
