Little is known regarding the reproductive biology of the south central Texas Eurycea. Given that my masters work is contingent on successfully reproducing these salamanders, I needed to explore different methods that would produce large quantities of embryos. To accomplish this I used hormones to induce ovulation and spermiation. I collaborated with the U.S. Fish and Wildlife Service Aquatic Resource Center at San Marcos, TX. As a refugium, reproducing viable offspring of endangered species is of high priority and ensures a sizable population at the Fisheries.
