Technical Abstract: ARS Corner The catfish spawning season is almost over and we have continued our studies on water molds (i.e., fungus) that grow on catfish egg masses. We have been comparing the effective treatments of copper sulfate, hydrogen peroxide, formalin and diquat that were previously determined through range-finding studies at SNARC. We have also done some preliminary testing with peracetic acid. These studies had temporarily taken a backseat to planning and organizing the annual Workshop in Little Rock, but these studies will be back in full-swing next year. The Final Study Report for the Copper Sulfate Target Animal Safety study on channel catfish eggs is in final review by Quality Assurance. We anticipate submitting the FSR to FDA/CVM in July. The high-density, low-flow columnaris disease method described by Drew at the recent Workshop has provided promising results and we are continuing to modify the system for optimum performance.
