Drs. Weddle and Kessler have been studying the spotted darter (Etheostoma maculatum) for several years. Although this species is declining in abundance in much of its range in North American, it is relatively common in Russell Creek and in Green River. We want to learn as much as we can of the basic biology of the species and have focused on its reproductive biology. We have learned about its spawning frequency and timing and have learned a little about its longevity and growth. During our observations of the fishes in laboratory aquaria, we observed changes of color in females during spawning. This has not been observed in other darters. We intend to spawn spotted darters in the laboratory, describe behaviors and quantify patterns of color change in both males and females. This work will involve field samples in May and June and laboratory work during the same period. If you are interested in animal behavior you should get involved with this study.
