  • Steroids were quantitatively determined in blood of females of a bony fish, Tilapia aurea, before and after initiation of spawning. The steroids were determined by acetylatihg them with labeled acetic anhydride, collecting the acetates from a gas-liquid chromatographic column and by achieving constant specific activity of 3 derivatives prepared from the steroid acetates. By initiation of spawning the following changes in concentrations of these steroids were noted: testosterone increased 8-fold… CONTINUE READING
