The droughts and increased heat has had negative impacts on local aquatic invertebrates. Aquatic invertebrates are adapted to survive in a particular range of temperature and habitat. But global warming makes it harder to survive. This could lead to the extinction of several species of aquatic invertebrates which in turn would lead to serious consequences of the ecosystem. Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters.
These pollutants have reduced water quality, contaminated soils, and damaged the Lake’s ecosystems. Pollution in wildlife has caused fish consumption to decrease, the spread of disease and viruses to increase, loss of fish and other wildlife stock. The closing of beaches and other recreational activities have been another direct result of the
This, in turn, can affect habitat quality for plants and animals that live downstream. Biodiversity may be lost if aquatic plants and animals cannot tolerate changing water conditions. When large volumes of water are pumped from a stream or river, water chemistry can change significantly with a drop in water level. Temperatures may rise and oxygen levels may drop, affecting aquatic species that don't have a wide tolerance. Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process.
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
(Ramel). Temperature of the water affects fish as in if the water is to hot or cold, the fish will die. So popular belief is that when the fish needs to warm its body up, it needs to move around more and eat more. These are believed to control fish’s body temperature. The amount of dissolved oxygen in the water depends on the temperature.
Raising Scoggins Dam would affect tributaries to Hagg Lake as well as Scoggins Creek downstream of Scoggins Dam. Therefore, the Project Area includes areas potentially inundated by the increased size of Hagg Lake as well as Scoggins Creek downstream of Scoggins Dam. Anadromous salmon and trout as well as resident fish species and Species of Special Concern (state or federal) occur within the Project Area. Methods Sources of existing fisheries information and data included the Oregon Rivers Information System (ORIS); StreamNet; Oregon Natural Heritage Program; Oregon Department of Fish and Wildlife (ODFW) project area files, reports, and data; Clean Water Services (CWS);
If there is more dissolved oxygen in the water then there will be more fish present in that area. What would your experimental approach be to test this hypothesis? I would test the amount of dissolved oxygen present in an area and count the number of fish in that area. Document all findings and compare. What would be the independent and dependent variables?
What caused this? Today I will have a chance to explain some of my ideas. To support these theories I will mention some documents to help in the essay, so let’s get started. [Doc.A] States: “…Adjacent river and creeks became brackish as water levels rose, reliable sources became scarce…as saltwater transfusion caused introduced filth tended to linger rather than wash away.” This may have caused the colonists to become sick. As the reliable water sources shrank and they were forced to drink the contaminated water.
The by-catch and pollution must also be monitored. There have been positive results from this new management overall, though many salmon populations as well as other marine populations continue to be in decline. It is important that we as consumers choose fish products from sustainable fisheries and understand what this means for marine environments. If salmon continue to be fished and farmed in ways that are damaging to the environment, collapse of the entire industry may occur. This can cause unforeseen economic and ecologic problems that may be irreversible.
Water is essential for healthy living and is important in meeting with Agricultural, Industrial and Domestic needs in both urban and rural areas. It is a common denominator required by all classes of society. However, due to an overburden of population, unplanned urbanization and industrialization, the quality of water has gone through high levels of degradation caused by the release of contaminants, detrimental to human health, into waterways such as streams and Rivers (Kumarasamy, 2015). When pollutants enter into a water system, they cause distortions within the water body as it moves downstream. It is common to consider pollution to streams as being transported from industries and cities which release waste water into water courses such as lakes, rivers and streams through designated and established point sources.
