This influences fish kill rate because higher oxygen levels in the water means more fish can coexist in the same location. a sudden decrease in oxygen levels and the fish will begin to die off because of lack of oxygen. Two sources influencing the levels of dissolved oxygen include the atmosphere and photosynthesis. The atmosphere provides oxygen for water; it dissolves slowly in the bodies of water. Photosynthesis is a important factor in the role of oxygen because plants take in carbon dioxide; meaning if there are plants there will be oxygen present. A large amount of activity in the water during night hours when plants cant photosynthesize leads to a decrease in dissolved oxygen. The cool water at night holds more oxygen but not enough for a busy body of water. Plants are beneficial in providing oxygen for water but they can also lead to decreased oxygen level. If the plant dies and begins to decompose, it is not beginning to take oxygen away from the water. The last major influence on an ecosystems dissolved oxygen level would depend if there were a “lake turnover”. The lakes surface turns over from the epilimnion (top) to hypolimnion (bottom) mixing the waters ecosystem. As a result, the lakes dissolved oxygen levels drop. Lake Turnover occurs mainly with strong wings or heavy rain that can start motion in the

The Blue Catfish represent 75% of the fish biomass and eat up every fish in the Chesapeake (fisheries.noaa). If this continues for any longer, the fish in the Chesapeake will be dead. Thus concluding, native species are evolved to live in a certain area best suitable for them.…

    They knew there would be no way to completely eradicate lake trout, but if no steps were taken for reducing the lake trout, it was estimated that cutthroat could be eliminated by up to 70% in 100 years (Duncan, Murphy, & Zale, 2009). They started to look at measures which could be taken for controlling the population. At a workshop in 1995, scientists determined that the use of gill netting as a method of gathering information that was needed for determining effective management in reducing lake trout population structure (Duncan, Murphy, & Zale, 2009). With gill netting, they could monitor how many lake trout was reproducing, what their diet consisted of and their habitat structure. Gill netting also provided a way of reducing the population, because when a lake trout was harvested they were killed instead of being released back into the lake.…

    Evolution is a necessity in our world. Organisms need to be able to adapt to their surroundings in order to survive, but it is sad to see that certain organisms have to evolve to survive in polluted areas, such as the Atlantic Killifish. According to JoAnna Klein, “Starting in the late 1990s, researchers became aware that the fish was tolerant of the toxic waters at the Lower Passaic Superfund Site.” Organisms should not have to adapt to polluted environments. In New Jersey, the law states that people can not eat the fish found in this area.…

The environmental engineer and writer of Scientific and Educational Publications talked about the shark numbers in the ocean and that the “populations of dusky, oceanic whitetip, and silky sharks in the Gulf of Mexico have declined by 79% to 97% since the 1950s due to overfishing. Massive declines are also reported over the same time period for blue, mako, oceanic whitetip, silky, and thresher sharks in the tropical Pacific Ocean” (“Threats to Aquatic Environments”).

    In California we all know how the Monterey Bay was a major fish canning area, made famous by Steinbeck’s famous book Cannery Row. But now it is a tourist site with a major aquarium, but not a major source of fish to feed people. Many other areas have seen their fish populations evaporate including the North Seas, Grand Bans, East China Seas, Peruvian Coast, cod fisheries off Newfoundland, sole fisheries in the Irish Seas and English Channel and elsewhere. Ocean fishing fleets have had to go deeper into the water to find fish, but deep water fish are often particularly vulnerable. For instance, the orange roughy can live to 149 years, but it cannot reproduce until between 30 and 40 years.…

The food chain makes fish prey for other sea animals and if fish are dying from the polluted water then that can also affect their predators that live in seas. Those that eat smaller fish will have less food around them to eat. In turn that will probably causes a lot more deaths in sea animals. Sea animals are not the only thing affected by water…
