<br />STATUS OF DRUGS AND CHEMICALS USED FOR DISEASE <br />CONTROL IN FISH CULTURE - 1987 <br /> <br />DOUGLAS L. MITCHUM <br /> <br />WYOMING GAME AND FISH DEPARTMENT <br />GAME AND FISH LABORATORY <br />UNIVERSITY OF WYOMING <br />P.O. BOX 3312 <br />LARAMIE, WYOMING 82071 <br /> <br />ABSTRACT <br /> <br />Therapeutants, anesthetics and disinfectants currently registered <br />or approved by the U.S. Food and Drug Administration (FDA), and/or U.S. <br />Environmental Protection Agency (EPA) for use in disease control in <br />food fish culture are presented. Problems involving some historically <br />important agents not registered or approved, efforts to register others <br />and the need for new disease control products are also discussed. <br /> <br />INTRODUCTION <br /> <br />A few months ago, for a meeting of hatchery superintendents, I was requested <br />to give a report on the use of drugs and chemicals for fish disease control. In <br />preparing for the task, I found that most of us in fisheries work are aware that <br />only "registered" or "approved" compounds are to be used for disease control and <br />other purposes. I also noted that there was much confus i on among us regard i ng <br />which compounds were "legal" for use, and how they were to be used, etc. Some <br />agents, used extensively in the past, were never registered or are no longer <br />1 ega 1 or approved. Much uncertainty and rumor exi st as to why th is is the <br />situation. Adding to the confusion, new compounds have recently been approved, <br />and research is in the progress to obtain a registered status on certain other <br />compounds. <br /> <br />.. <br /> <br />Thi s presentation is intended to provi de some hi stori ca 1 background and <br />clarify the present registration status of fishery drugs and chemicals. Remarks <br />are generally limited to those agents used for disease control in fish culture. <br /> <br />The existinq federal requlatorv situation <br /> <br />The U.S. Congress passed laws which empowered the Environmental Protection <br />Agency (EPA) with control of the use of pesticides and the Food and Drug <br />Administration (FDA) with control of the use of drugs. The formation of policy, <br />rules and guidelines to carry out these laws was also given to these respective <br /> <br />17 <br />
