Distribution of Fish Species in Cedar Lake

With over 13,000 described species of freshwater fishes, diversity within aquatic systems can vary extensively. At the local scale small changes in the diversity of fish species within an ecosystem will modify processes within the ecosystem such as community decomposition and metabolism. Recent analyses indicate that actual species diversity within small, shallow ponds may be higher than previously thought. Fish species distribution will differ based on location within the aquatic system relative to the species’ position in the trophic web. We will measure both quantitative and qualitative differences among species at different locations within of Cedar Lake, expecting to find a decrease in both species diversity and total number of fish as the depth increases. We will count the number of fish species and the total number of fish at each depth and use t-test analysis to determine if depth influences fish diversity
