Abstract
Crayfish foraging behaviors can alter aquatic ecosystems. Starvation and time of day are two potential factors that can influence those foraging behaviors, but the interaction between the two variables has not been studied. In this study, we observed the movement of fed and starved crayfish during the day and at night in the presence of both water and food odor. We calculated both total movement and change in movement and predicted more activity when starved and at night. Crayfish did not show a preference for day or night, nor did they display significantly more movement when fed or starved. These results do not match previous literature, meaning that further research on these factors is necessary, especially in Cambarus acuminatus.
