CFI propagated the Speckled Darter 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 30 individuals for this research. Since this work we have also worked with two other species closely related to it, the Blueside Darter and the Bluemask Darter. It is likely we could apply our knowledge of rearing these two other species to the Speckled Darters in the future.
