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
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases. Construct a hypothesis – Based on your observation in Question 1 and your background research in Question 2, develop a hypothesis statement that addresses the relationship between dissolved oxygen in the water sample and the number of fish observed in the body of water. Answer = If the dissolved oxygen level is high in a body of water, there will be a low number of fish. The higher the dissolved oxygen level the higher the death rate of the current fish. 3.
Red is the endangered areas In image 2, the most endangered reefs are in areas that are considered “Third World”, where populations have limited access to education. The people here are concerned mostly with putting food on the table now, later can wait for another day. There is a problem with reef systems today that directly comes from people who probably did not know that they were causing it. Runoff from sewers, especially untreated sewage kills corals by: * Suffocating corals and zooxantheallae by covering them with sludge and cutting off
They accomplish this by feeding on algae and bacteria. 8 Species of mussels are native to the river. The most prevalent are the eastern elliptio mussel and the eastern lamp-mussel. Mussels are eaten by a variety of birds, turtles, fish, muskrats and other mammals. Zebra Mussels are an invasive species that can cause harm to native species by attaching themselves to their shells preventing free movement and can even cut off their oxygen
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. During the drilling process, wells for drinking water may become polluted with a variety of contaminants, such as methane gas. Here I have a video showing exactly what the drilling is doing to peoples water supply. Gas wells require miles of roads and pipelines to move the natural gas from the drilling site to the market. Construction of these transportation corridors can break up the natural landscape and impact wildlife habitat.
These slimy mats of algae foul beaches and the taste of drinking water and produce toxins that are dangerous to humans (Magnien, n.d.). People who regularly consume a lot of fish will have larger levels of toxic chemicals in their bodies than those who only eat fish occasionally. While scientists are still studying the effects of high chemical levels in humans, studies have suggested that toxic chemicals can lead to reproductive problems, cancer and neurological disorders. People who are most at risk of health problems due to contaminated fish consumption are those with weakened immune systems, including children, pregnant women and the
Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands. Salmonella is also the leading cause of food poisoning in the United States. 2. How is this infectious agent transmitted through food or water? Salmonella can be contacted by usually eating or drinking something
It feeds on ectoparasites or dead tissue that it picks from the body and oral cavities/gills of these fish (e.g. ; Tangs or Groupers) in the wild or in the aquarium. This also helps to protect the fish from contracting diseases and infections. Many fish value its services so highly that they will allow it to clean the inside of their mouths, and not harm it. Some fish, though, such as Hawkfish, Lionfish, and some predatory shrimp and crabs may eat the Scarlet Skunk Cleaner Shrimp.
Another item pointed to pesticides, fertilizers and road salt as additional contributors to the pollution problem. And even further a New York Times article spoke about the algae blooms resulting from phosphate pollution. The lake has experienced a decline in its fish production attributed to the “dead zone” resulting from algae blooms. Further, the fish caught have ingested plastic and plastic the article argues attracts chemicals like bisphenol A (BPA) a contaminant said to affect the endocrine system. This
