Government stewards of the salmon resource of the North Atlantic must communicate and cooperate to eradicate ISA before it becomes endemic. Sharing the science already learned by researchers in Scandinavia and the United Kingdom is essential to developing an effective management strategy. Secretary of Agriculture Ann Veneman acknowledged the importance of ISA when she authorized the expenditure of $8 million in fiscal years 2002 and 2003 to control and eradicate the disease. APHIS received pass-through funding for ISA research and control efforts in December 2001 and, in spring 2002, put into place program standards to eradicate the disease. In September 2002, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) hosted a symposium on ISA with assistance from the U.S. Department of the Interior’s U.S. Geological Survey and the U.S. Department of Commerce’s National Marine Fish- eries Service. The American Veterinary Medical Association supplied organizational expertise as well. This 2-day event was held in connection with the International Symposium on Aquatic Animal Health in New Orleans. These symposium proceedings capture not only the formal scientific presentations but also a court reporter’s transcript of the informal presentations at the end of the second day, which addressed real-world considerations for ISA prevention, control, and eradication. Given the importance of the information shared at the meeting, APHIS staff members have pulled out all the stops to produce this book in 8 months. Once our supply of free copies is exhausted, copies can be purchased from the U.S. Department of Commerce’s National Technical Information Service, 5285 Port Royal Road, Springfield, VA 22161. Also, a .pdf version will be placed on the Web site of APHIS’ Veterinary Services at <http://www.aphis.usda.gov/vs/aquaculture>. I hope you find the information presented at the conference as useful as I did. W. Ron DeHaven Deputy Administrator, Veterinary Services Animal and Plant Health Inspection Service U.S. Department of Agriculture Washington, DC iii Foreword On behalf of Secretary of Agriculture Ann Veneman, APHIS Administrator Bobby Acord, and the Deputy Administrator for Veterinary Services, Ron DeHaven, thanks for your interest in learning more about infectious salmon anemia (ISA). This book documents the scientific papers presented at a 2-day symposium held September 3–4, 2002, in New Orleans, LA, during the weeklong meeting of the International Symposium on Aquatic Animal Health. In addition to 18 formal scientific presenta- tions, we have captured comments from individuals who spoke briefly during an open forum held at the end of day 2 of the symposium. While the formal presentations were submitted in advance and put through rigorous peer review, the forum talks were not vetted or corrected, other than for clarity. We took the precaution of using a local court reporter to capture the forum talks verbatim since those speakers were not required to submit manuscripts. The meeting itself was structured to provide an international response to ISA using the themes of prevention, control, and eradication. Four moderators introduced the main subject topics and the speakers’ presentations in the areas of international applied research response, diagnostic and laboratory response, management response, and regula- tory response. Our speakers provided the most current international knowledge on the extent of ISA infection in various countries, including the number of salmon farms affected, depopulation statistics, and related issues such as indemnification, regulation, and management. Also covered were effective and ineffective management procedures, projected outcomes of procedures in current use, and new developments in applied ISA science and research, including diagnostics and prevention. Presenters represented five countries: Canada, Chile, Norway, Scotland, and the United States. When the number of speakers reached 19, we split the meeting into 2 sessions on successive days. The second day culminated in a panel discussion entitled Practical Future Consider- ations for ISA Prevention, Control, and Eradication. This open forum was designed to allow audience participation and permit ISA experts not on the official agenda to address topics of interest. It always takes a team of workers to organize and execute a meeting like ours and to bring its results to printed form afterward. We will give you more particulars on this process and identify all the major players in the Acknowledgments section immediately following this Foreword. Should you wish to contact any speakers or forum participants for more details, appendixes 1 and 2 provide complete contact information. iv We look forward to working with you in helping the aquaculture industries and natural-resource agencies manage ISA. The symposium held in New Orleans was an important national and international step in coming to grips with this significant aquatic animal health threat. Otis Miller, Jr., D.V.M., M.S.

Similar efforts are being mounted in Canada, Scotland, and Norway, all of
