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.
This devastation affects a majority of the U.S. being one of our largest sources of fresh water, and will only continue to deplete, as companies carelessly dump their waste into the lake. Consumption of fish from this lake will soon be obsolete if immediate action is not taken. These are all things that need to be considered by industrial businesses, families, merchants, fishermen, and environmentalists. As long as the waters are polluted the economy will experience great loss, and may even see jobs created by the Great Lake, eventually
Farm raised fish versus wild caught Cul 110 exam #3 Alexis Halstead There have been many different long standing arguments about the differences between farms raised fish and wild caught fish. There are good arguments against which is better than the other. Although these farming practices have their difference, eating fish has great health benefits and that should also be taken into consideration when deciding which product you will be purchasing. Fish are widely advertised for there health benefits, but there are many different controversies surrounding how they caught and able to be produced in mass quantities. Eating about two servings of fish per week provides healthy amounts omega-3 fatty acids that can help to lower cardiovascular disease.
This industry currently provides many jobs and has become important economically to the area. The salmon industry as well as other human influences are causing problems for the fish. Their complex life cycle and habitat needs are being adversely affected, and their numbers are decreasing. They are becoming less of a sustainable resource. The effects of industry
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.
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.
• Fish: The Rideau River has a variety of cool-water fish. Sunfish are the most predominate but there is also a wealth of minnows, pike, catfish and other bottom feeders. The rarest species of fish in the Rideau River are the mottled sculpin and emerald shiner. • Native Mussels: Mussels are an important part of the Rideau Rivers ecosystem by filtering around 8 gallons of water in a single day. They accomplish this by feeding on algae and bacteria.
However researchers are not completely sure what is polluting the lake but they say they need find out soon so the fish can be saved and the lake can be salvaged. Vast amounts of wilderness has been ripped up from the soil to make room for this large project to take place, this has affected the once natural Greenfield site and disrupted the biodiversity of the land. People living in the area say that is looks like ‘mother nature has been raped’. An economic effect includes the amount of money that has to be spent on infrastructure of the project and also the clean up process after the job has been done.
No one knew it would become a major invader of Florida’s lakes and rivers” (Susan Cerulean). As the imported Hydrilla became more abundant in Wakulla Springs, the reader learns that certain species have developed to avoid Wakulla Springs and find another habitat. Such as anhinga, yellow-crowned night herons, apple snails and limpkins. The people in charge of Wakulla Springs clear, take out and get rid of the Hydrilla infestation in Wakulla Springs. After the narrator left Wakulla Springs, he took a canoe ride on Wacissa and compared the states of Wacissa and Wakulla Springs.
More updated methods of accelerating decomposition have been introduced in more recent years, however, these liquids are still potentially leaking. Even state-of-the-art landfills contribute to massive pollution to groundwater. While grasses in the creek Royte describes, act as erosion control and natural filters and some organisms seemed to continue to thrive is such horrid conditions, the author mentions that she later learned that pollutants from the water were showing up in bird eggs and chicks and jeopardizing their long term
