Development of a Bioassay to Quantify Vitellogenin in the Endangered Razorback Sucker followed by Annual Cycle Characterization of Vitellogenin and Steroid Hormones as a Measure of Reproductive Health

This research project objective is to measure vtg and steroid hormones in sexually mature, adult razorback sucker over one annual -estradiol,ß reproductive cycle. We will measure vtg and steroid hormones (17 11-ketotestosterone, and testosterone) in blood plasma of razorback suckers once a month for one year to document concentrations throughout More...
