We investigated the dispersion of Rhinichthys atratulus in Warm Spring (Huntingdon PA) and how it may be affected by water chemistry factors such as temperature, pH, conductivity, and dissolved oxygen. We went out to Warm Spring on three different days and divided the stream up into 4 sections in 10-meter increments. In each section we recorded the physical measurements and counted how many of the fish we would observe. Our hypothesis about the dispersion was proven wrong using a one-way ANOVA analysis and variance-to-mean ratio. We concluded that the dispersion of Rhinichthys atratulus had a uniform distribution as opposed to the clumped distribution that we predicted.
