Algae Growth In Jackfish Lake

Phytoplankton are microscopic photosynthesising organisms which live in water. In favourable environmental conditions they have a very high rate of reproduction. They are eaten by microscopic animals called zooplankton. In an investigation, samples of water were removed from a lake at intervals over a twelve-month period and the biomasses of these organisms were determined. The results are shown in the graph.

Brooks and Dodson, the authors of the article titled “Predation, Body Size, and Composition of Plankton”, conducted research on the effect the small fish called Alosa Pseudoharengus has on an ecosystem, more specifically, different lakes in New England. Along with the data they collected on the aforementioned matter, they studied the sizes and the composition of the miniscule zooplankton inhabiting the lakes, and compared it with that of the Alosa. Their research uncovered important facts regarding water ecosystems and how they are so easily thrown off balance.

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

Lake Erie is thriving biologically but not in the way one might think. It’s poisoned with toxic algal blooms that grow in the phosphorus-concentrated waters millions of Canadians and Americas alike depend on for drinking water. Unfortunately, this is also not the first time this has happened to the Great, not-so-great Lake.

In this research paper I will talk about how a large decrease in the algae population in the Chesapeake Bay will cause problems for not just fish and other species but the people who fish and make a living off of it. A large decrease in algae population will have a domino effect on the food chain. Having a major decrease in algae will hurt how others species live and protect themselves.

Phosphorus, “...the primary algae-feeding nutrient in Lake Erie, and contributed to the largest algae bloom in history last year” (McCarty, para. 3), is a key factor in how

Algae blooms have been an issue in the Chesapeake Bay, especially in the Baltimore Inner Harbor. Algae is a natural and critical part of the ecosystem, however in large doses it is harmful to the plants and organisms within the ecosystem. Algae blooms can block out sunlight and kill other plants in the water. Algae depends on various factors such as water, nutrients and carbon dioxide to grow. Eutrophication of the Inner Harbor has lead to algae blooms that have caused large fish kills in the past. When there is an over abundance of certain chemical nutrients eutrophication can occur. Runoff from land and farms is the main cause of excess nutrients into the water. The most common nutrients that are related to algae outbreaks are nitrate nitrogen and phosphate. In addition, a lack of dissolved oxygen can also be an indicator for the process of eutrophication and risk of an algae outbreak. A particular type of algae commonly found in Maryland is known as Prorocentrum minimum. Prorocentrum tends to cause “mahogany tides” causing water to be brown and have an odor. There has been a campaign launched by the Healthy Harbor

Located on the northern side of Dakota County, Sunfish Lake, Minnesota, is a small community that is proud of its legacy. The community treasures its solitude yet understands being apart of the thriving Dakota County. The city is bordered by Highways 110 to the north, 3 to the east, 60th Street West/Peiper Road to the south, and Delaware Avenue to the west. I-494 runs through the city as well.

As the population on earth increases ,overfishing has become a growing issue in all parts of the world. Fish is a vital food source for many, in the world and counts for many of the cultures and heritages in the world, which means there is a high demand for it . This high demand has caused overfishing to occur. This is a cause for concern since due to the development of better technology, there is a higher risk of overfishing if not managed properly. Canada in particular has been facing the problem overfishing for years now. Due to Canada’s issue of overfishing, the environment and wildlife as well as human settlements all have negative impacts ,therefore a sustainable solution must be implemented. If action isn’t taken, Canada’s issue of overfishing will continue to worsen.

There are several environmental concerns affecting the community of Lusby, Maryland, but of main concern is the cyanobacteria growing in the Chesapeake Bay. The blue-green algae called cyanobacteria is infesting the waterways in and around Lusby causing a hazard to the community. According to National Geographic (n.d.), the Chesapeake Bay was one of the first waterways recognized in the 1970s having overgrowth of cyanobacteria. Cyanobacteria contains both an algae and a bacteria and when growth exceeds space and the algae begins to die, two issues occur: toxins are produced and released which are harmful to both humans and animals and hypoxia follows as oxygen is consumed in excessive creating a dead zone in the water for all other living

When we factored in the control jars, we revealed inconsistencies in the data, which led us to believe that there were unacknowledged errors in our experiment. Had the experiment proceeded as planned, our control jars would have contained the highest concentration of algae due to the absence of any consumers. Without any consumers, the algae grew without any limiting factors. Since those jars were the controls, it suggested that the errors occurred in our experimental jars. The algae concentration in the jars of 3 brine shrimp

What if there was an up and coming fuel that has the properties of normal oil, but its side effects were not nearly as bad? Would you support it? Well there is such a thing. It has been around for a few years, but only in the near future does it have the potential to do good on a worldwide scale. This innovation is called algae biofuel. Algae biofuel is a fuel just like gasoline or diesel, but instead of being mined from the ground, causing irreparable damage, it grows in a pond and actually has positive side effects on the environment. Algae Biomass Organization states, “Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 percent compared to petroleum fuels.” Algae biofuel could be one of the solutions to our polluted atmosphere.

In recent years, the prevalence of algae blooms in coastal areas such Florida has somehow become more and more apparent in what is most-frequently touted as the states’ most attractive feature: its bodies of water. Most residents are aware of the fact that this swelling frequency of algal blooms isn't natural, but if not Mother Nature herself, who, or what, is to blame? Factors that plays into the amount of green that we see in our local lakes and rivers may appear trivial or impossible to solve, but each carries consequences that, in short, are not beneficial for the environment nor its inhabitants. These factors span from certain chemicals used in agriculture to specific topographic features and alterations that farmers can utilize in order to reduce the amount of runoff that escapes their land. Runoff is the term for precipitation that flows from one area to a new one as it was not absorbed by the soil.

Eutrophication is a natural process that lakes and certain bodies of water undergo. Eutrophication happens by having a significant level of biodegradable waste in a body of water. The nutrients in the water promote growth of primary producers which has a positive impact on consumers. These nutrients usually cause bodies of water to be cloudy, turbid, have a high number of primary producers, and promote the excessive growth of algae (Koechli, 2015). This then causes the body of water to reduce its dissolved oxygen level, and dead biomass to accumulate. Although it is a natural process, humans can affect these bodies of water by inserting a surplus of nutrients. This process is called cultural eutrophication, which is considered a form of water pollution (Koechli, 2015). This pollution is often caused by fertilizer run-off and much more. It causes the overgrowth of aquatic plants. These plants quickly become crowded and have to compete for space and sunlight. Because of this, aquatic life is threatened due to the low dissolved oxygen, and blocked sunlight. Cultural eutrophication is
