Title: Effects of Congregated Salmon on water quality below versus the water above the weir Purpose: This study consists of testing water quality in general as determined by two tests. One done above the weir where there are no congregated salmon. The other test will be done below the weir where the Salmon are congregated. Background: The Little Manistee River exists due to several swamps that are located in eastern Lake County. The river flows through Lake County, Mason County and Manistee. After traveling 55 miles from Mason County it then empties into Manistee lake in Stronach. After entering the lake it then Empties into lake Michigan through the channel. Around the little Manistee there are mostly Northern hardwoods and Conifers. …show more content…
The tests were taken along the Little Manistee watershed. Tests were done above and below the weir. The departure time was around 9:00 Am on 9/22/15. Weather conditions were good, warm and sunny. A series of tests were done to determine water quality. One test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph it can be unsuitable for aquatic life. A very low ph level causes the release of metals from rocks or sediments. This can then affect fish and their fry. Throughout the test for total dissolved solids things like residential runoff, discharges from industrial sewage treatment plants, and minerals are detected. Water is a powerful solvent, and can easily pick up impurities. High total dissolved solids alter taste and quality of water. The turbidity test is responsible for measuring the cloudiness of water caused by sediment particles. The particles in the water absorbs heat from the sun which makes the water warmer. This then reduces the amount of oxygen in the water. High turbidity can also mean sediment pollution. The …show more content…
With a rating of 69.67 water quality is better below the weir than above, with a rating of 67.73. While looking at dissolved oxygen and Biological Oxygen Demand it is seen that above the weir has a better level of Dissolved oxygen. But both below and above have the same results for BOD. This means that normal levels of oxygen demand is present, not to much oxygen is being used or needed by the river. The river can handle the amount being used by anaerobic bacteria and other aquatic life. There is more dissolved oxygen above the weir than below. This allows for fish who need clear bubbly water to survive better. The difference of dissolved oxygen above and below is only one point difference of the q value. This means that salmon and other fish will be able to live in both places. While looking at the Ph levels of the river it is seen that below the weir has the better value. At a value of 7 it is determined neutral. The water above the weir is considered more acidic. When testing for Nitrates and Phosphates in the river it was shown to be at equal levels both above and below. By the results it shows there is not a dangerous level of either anywhere along the river. Too much of either causes algae and plant growth, bacteria then breaks it down which can lead to eutrophication. With the turbidity test it shows above the river having a higher
NTRODUCTION The water body ‘St.Croix’ is a river which covers an area of 4271km2, and it flows along New Brunswick and Maine and acts as a water boundary between Canada and United States. “Because of its strategic location, the river has played a unique role in the history of Maritime Canada and the U.S. and remains important for these reasons today” (CHRS. 2007). Picture 1 Source: http://www.ijc.org/rel/boards/saint/watershed_report_e.htm Picture 2 http://www.naturetrust.nb.ca/wp/blog/conservation-planning-st-croix-river/ The picture shows the geographic position of St.Croix river watershed and the watershed itself.
We found a little number of Phosphates and Nitrates in the water. That is healthy because these two chemicals are in fertilizers and detergents, they can harm the creek and all the creatures living in the creek. They get into the water through the eutrophication process. Bacteria eat phosphates and nitrates so that means there is a little number of bacteria in this creek. The dissolved oxygen level of the creek is high which is healthy.
The interior dykes can adjust the water levels and influence the vegetation in this way. However, since the management of the area has improved, the influence is less than Burns Bog. In Watershed Park, the artesian
In 2012, mean daily growth rates in terms of differences of fork length (weight) from March 28 to April 26 were: 0.278 mm/day (0.048 g/day), 0.408 mm/day (0.078 g/day), 0.255 mm/day (0.048 g/day), and 0.293 mm/day (0.048 g/day) at the Merced River Ranch, Robinson’s restoration reach, Gallo’s property, and Livingston’s scout camp, respectively. In 2013, mean daily growth rates in terms of differences of fork length (weight) from March 18 to April 15 were: 0.474 mm/day (0.074 g/day), 0.497 mm/day (0.077 g/day), and 0.204 mm/day (0.025 g/day) at the Merced River Ranch, Robinson’s restoration reach, and Gallo’s property, respectively (Figure 4). In 2011, mean daily growth rates of juvenile Chinook salmon inside enclosures were higher at
Bill McEwen does not only use ethos and logos to express and reach out to the reader, but he also uses pathos. With pathos, the author can get into the reader’s mind and make them feel a certain way with his use of words. An example of pathos in the article can be easily shown when McEwen says” The reality is, our federal and state government will spend hundreds of millions-if not billions- of dollars in coming years on a program that will yield a salmon exhibit instead of a substantial fishery”(McEwen 9). McEwen’s use of pathos can be clearly identified in this phrase by looking at the way he states what he is saying. Here, McEwen does not use any facts or famous experts, but he does say this in such a way that the gets the reader really thinking
Approximately four-fifths of the Tar-Pamlico River Basin is located within the Coastal Plain region of North Carolina while the remaining one-fifth lies within the Piedmont region. Slow Moving streams surrounded by swamps, forests, low-lying marshes, and estuarine areas characterize the water flow in the Coastal Plain region. The Coastal Plain portion features slow-moving blackwater streams, low-lying swamps, and productive estuarine waters. The larger waterbodies are meandering, often lined with swamps and bottomland hardwoods, and often have naturally low dissolved oxygen and pH. Soils are deep sands that have a high groundwater storage capacity. There are 80 miles of impaired stream in the Tar-Pamlico River basin and all waters in the basin have a supplemental classification of Nutrient Sensitive Waters (NCDWQ
The marshland itself harbors a wide array of ecosystem services. The water in the marshland at the Shawsheen River site has a pH of 5.5. It is slow moving with a speed of 36.88 meters/second. Where the water is moving faster there is more oxygen; whereas, where the water is moving slower, there is more Carbon Dioxide. This is a provisioning ecosystem because when the dam is removed, there will be less carbon dioxide because of the increased water velocity.
Human Interaction and the Salmon of the Pacific Northwest The Pacific Northwest is home to a wide variety of species. Its ocean, forests, streams, and rivers allow for vast amounts of animals to reside in the area. A particular inhabitant, the salmon, is unique in that it not only lives in both salt water and freshwater, but that it also returns to its own birthplace to spawn. Because of these unique characteristics, the salmon has become a symbol of the Pacific Northwest.
When it comes to farmed salmon the federal and provincial levels of government in Canada, surprisingly, play two very separate roles. The federal government mandates jurisdiction of the Department of Fisheries and Oceans, thus trying to protect and ensure the safety and sustainability of the wild salmon populations. However, being a federal level of regulation, the government also is looking to make the best political and economic move for Canada. The best economic move for the entire country is not necessarily what is best for the wild salmon ecosystems and this caused friction over the two sides within the department. The promotion of the aquaculture of farmed salmon is where the Canadian government has chosen to spend a large portion of
Gila trout are endangered in some stretches of water that are managed as designated wilderness. A hands-off policy would be their doom. Because exotic trout species now swim in the same streams, Gila trout can survive the competition and the temptation to interbreed only if they swim in isolated tributaries. In which a water-fall blocks the upstream movement of other fish. Two decades ago, one such tributary was fortified.
The Ohio river ranked first for toxic discharges in 2007 followed by the Mississippi . U.S. legislation enacted in 1972 to restore and maintain clean and healthy waters. The work was very treacherous and took a long time to accomplish. In the late sixties people noticed that our waters were very unhealthy
Endangered Native Atlantic Salmon: Salmon Presentation Project (Not a Final Draft) Salmo salar, most commonly known as Atlantic Salmon, was once native to almost every freshwater river connected to the Hudson River. Due to what people have treated salmon during their history, many species have been endangered and even extinct, this includes the Native Atlantic Salmon. When people first came to Maine, Atlantic Salmon was the main source of food to eat. The population was still very steady then, but it wasn 't until the early 1800’s that populations decreased.
The Cullowhee Creek is a small source of water that runs through Western Carolina University. The creek begins further up the mountain, then runs into the Tuckasegee River, which then flows into the Tennessee river, then the Mississippi, and finally, into the Gulf of Mexico. In this activity, we monitored the creek to determine its health. In the Riparian Inventory activity, we rated various aspects of the creek.
The high amount of limestone in the creek neutralized the acid rain that was pouring on the creek. This can also make ph scale go into the alkaline side of the ph scale. The ph scale is healthy, because if it was to acidic it will be unhealthy for the fish. These were some of that factors that were in the
Our hypothesis was that the crayfish would show metabolic compensation when they are acclimated at different temperature. Our prediction for this experiment was that there would be no difference between oxygen consumption between cold acclimated crayfish and warm acclimated crayfish. Based on our t-test result, the p value was greater than 0.05(p=0.25). Therefore, it supported the prediction that there was no significant difference of the rate of oxygen consumption between warm and cold acclimated crayfish. The same thing was also supported by the Q10 value(Q10 = 1.05), which meant that crayfish showed a perfect compensation.
