Technical Abstract: ARS Corner Aquaculture America 2011 The Aquaculture Drug Research and Drug Approval Status (formerly Therapeutic Drug Research) special session was a big hit again with 12 presentations and plenty of discussion. The session is organized and moderated by Jim Bowker and Dave Straus and this was the 9th year we have held this session focused on research in aquaculture therapeutants. 17a-Methyltestosterone As mentioned previously, we collaborated with the people at AADAP on the 17a-methyltestosterone Target Animal Safety study with tilapia last summer. We have finally completed the painstakingly thorough QA audit to provide AADAP with an ‘in-life study’ report. The histopathology is almost complete and we will assist AADAP with the Final Study Report. Funding from the Western Regional Aquaculture Center helped defray the costs of the study and we thank them. FDA Stuff In December, the FDA accepted a Final Study Report for the supportive effectiveness range-finding studies of CuSO4 on fungus of channel catfish eggs and we will prepare the pivotal dose-confirmation Final Study Reports to complete the technical section as time allows. Other Stuff We recently completed a study with a natural outbreak of columnaris in catfish and used our low-flow aquarium system to test effectiveness of KMnO4 and CuSO4. The duration of the experiment was 7 d, and the survival on day 7 was 38.5%, 72.7% and 52.3% for the control, CuSO4 and KMnO4 treatments, respectively. Only copper sulfate was significantly different from the control (P = 0.05). This research will be presented at the Eastern Fish Health Workshop. Sadly, Drew Mitchell retired from SNARC in January this year. We will miss his valuable contributions to disease research and his endearing ways. We had a fantastic retirement reception for him with many great pictures of Drew in his different phases through the years. He worked here for 34 years and was our walking encyclopedia on fish diseases, any trivia about Stuttgart or whatever else. He will be sorely missed, but is only a phone call away.
