Fish

**__Fish at Flat Rock Brook __**

Hi! This is Ali and Gabby's watershed project on fish. We are trying to find where in Flat Rock Brook, fish live and why they live there. We have been there several times (once in the fall, winter, and spring), but have only seen the fish on our last visit there, on May 21. For our project we will be using different tools such as a pH meter, GPS, and a DO, or dissolved oxygen, meter (see picture below) to help us figure out why fish live in the places they do. We will be testing for the acidity, temperature, and amount of dissolved oxygen of the water. Feel free to look around our page, we hope you like what we see.

  Why use the DO meter? The level of dissolved oxygen in the wate r can significantly impact the lives of fishes. They are sensitive to certain levels of dissolved oxygen. In addition, Fish are very sensitive to changes in pH as well so perhaps a pond at Flat Rock Brook might have no fish beause of unfavorable levels or acidity, or the opposite: fish might dwell in huge schools in one area because the pH is just right. Lastly, why did we choose to check the temperature of the water? Temperature is an important factor as to why fish live where they live because obviously fish cannot make habitats in water that is either too hot/cold. Luckily, the pH meter and the DO meter both had thermometers to calculate the temperature of the water. (See the links for pH and the DO meter for more information)
