Etheostoma douglasi | Tuscaloosa Darter

CFI propagated the Tuscaloosa Darters in 2003 for USDA Forest Service, Southern Forest Reseach Station in Oxford, MS. We were tagging the otiliths of these fish with an oxytetracycline dye and then sending the fish to Susie Adams. Susie was analyzing the growth rate of the otoliths. This was very useful information because we knew their exact ages of the fishes when their otoliths were marked. Hopefully this information has been put to good use in darter aging by looking at the otoliths.


This was a moderately challenging species to work with, but over a couple years we were able to provide 61 individuals for this research.
