The objective of our project was to determine if climate affects the growth of the Striped Bass population. We selected this project because Striped Bass are an important part of Lake Texoma and the economy of surrounding cities. Multiple experiments were done to draw conclusions about the Striped Bass population in Lake Texoma.
Our hypothesis states when the climate temperature increases Striped Bass will struggle to survive. We discovered as the temperature increases, even though there is a larger food supply, there is less dissolved oxygen and fish could die. The fish would have a better chance of survival in a cold environment, despite the fact that there would be a shorter food supply. There would be more dissolved oxygen and the fish would have a greater chance of survival.
We took field trips to bodies of water to learn about aquatic life and water content. We interviewed fisheries biologists and college professors. We studied habitat, the food chain, dissolved oxygen, and reproduction patterns of Striped Bass. However, the data was based on averages, which led to inconclusive results. Further studies and analysis will have to be performed to be able to conclude if climate has a direct impact on the reproduction of Striped Bass in Lake Texoma.

The pH of 7.0 makes me wonder if the alkalinity of the water is quite high. If the alkalinity is high it might be due to limestone. Alkalinity is a measurement you might want to add to your collection regime. It might also be interesting to see how the data you collected change throughout the year and over multiple years. Are there tributaries that lead into Lake Texoma? It might be interesting to test those as well.
There is an interesting relationship between dissolved oxygen and temperature - it's inversely related, meaning that as water temperature increases dissolved oxygen decreases and as water temperature decreases dissolved oxygen increases. This is due to the solubility of gases in liquids (Henry's Law). We look forward to seeing more hydrology data!

From the students at the Main Street Intermediate School -

"• It was very interesting to learn how a lake is stocked with a particular species. If the striped bass is really adaptable, are there other fish/organisms lower in the food web that are affected by climate change that will ultimately affect the population of striped bass?
• Are the striped bass the largest game fish in Texoma?

From a student at West Haven High School-

"Great information! I felt really informed about the project you guys were working on and its results! Even though the results didn't show much,there's definitely a correlation between dissolved oxygen and the striped bass population. You might want to try testing the water supply for nitrites and nitrates as well as amonia and other chemicals to see if there are any oher external variables affecting the fish population. That might help make your data more efficient and accurate!"
