Walt, a stalwart supporter of the aquaculture industry in the northeastern U.S., encouraged this effort. He envisions an extension, research, and regulatory community that is more responsive to the needs of the industry, an industry that is better informed about the risks inherent in the business, and one that is better able to address and manage production hazards on the farm. Acknowledgments: We gratefully acknowledge the following farmers whose experience proved invaluable to this effort: Charlie Conklin, Paul Dobbins, Betsy Haskin, Rick Karney, George Mathis, George Nardi, Carter Newell, Jules Opton-Himmel, Dale Parsons, Robert Rheault, James Tweed, John Waylon, and Lawrence Williams. These farmers shared an immense amount of knowledge in an effort to educate new entrants to the industry. In addition, several researchers, aquatic animal health professionals, regulators, and extension professionals participated in workshops and focus groups and provided valuable feedback on this publication including: Chris Bartlett, Paul Bowser, Michael Brown, Marta Gomez-Chiarri, David Grunden, Jurij Homziak, Bill Kelleher, John Kraeuter, David McGhie, Jeff Mercer, Dana Morse, David Noyes, Michael Oesterling, Dina Proestau, Nathan Stone, Marc Turano, Colby Wells and Charlie Yarish. Funding This project was funded through the USDA National Institute of Food and Agriculture Northeastern Regional Aquaculture Center grant #Z540501 to the Northeast Aquaculture Extension Network. 7 8 AQUACULTURE MANAGEMENT GUIDE: Manual for the Identification & Management of Aquaculture Production Hazards Preface Each year, the aquaculture industry experiences significant economic losses as a result of pathogens that cause disease, pests that render product unmarketable, operational mishaps, adverse weather events, and closures of harvest areas due to the presence of organisms with the potential to cause human illness. Collectively, we refer to these as aquaculture production hazards, which present considerable risk to operations. Massive loss of farmed product and human illness caused from ingestion of unknowingly contaminated product both adversely impact profitability, trade, and public perception. The ability of professionals to respond to problems and assist farmers is often limited by a lack of farm-level monitoring, record keeping, and farmer knowledge of hazards and hazard management strategies. Frequently, the causes of mortality events remain unknown or are identified when it is too late to prevent, control, correct or mitigate. Often, key pieces of information are missing from farmers’ requests to identify and correct the hazard, limiting the response from the extension and aquatic health professional community. To respond to this problem, the Northeast Aquaculture Extension Network (NAEN), a group of extension professionals from universities and industry associations across the northeastern U.S., together with researchers, aquatic animal health professionals, and experienced industry members has developed this comprehensive publication that identifies strategies to address aquaculture production hazards. The manual includes science-based information about major production hazards facing farmers, including: predators, diseases, parasites, organisms that have the potential to cause aquatic animal illness and human illness (e.g. toxic algae), biofouling, spread of invasive species, and other operational and environmental hazards. The manual also includes guidelines for environmental monitoring, evaluation and sampling of stocks, record-keeping procedures, and state- by-state contact information for whom to call when a problem occurs. The manual incorporates best management practices and biosecurity measures developed through research and outreach efforts funded by the USDA Northeastern Regional Aquaculture Center (NRAC) and others. Improved knowledge of hazards associated with aquaculture production is the first step towards developing or improving risk management strategies. Use of appropriate farm monitoring protocols and record keeping will help aquatic animal health professionals respond better and more efficiently to animal illness or mortality events. If the causes of such events are identified quickly and definitively, future losses may be minimized or prevented, leading to increased production and profitability. The potential for realized economic benefits is significant; operators who plan proactively to minimize production hazards may have a competitive advantage in the marketplace. 9 Table of Contents 10 AQUACULTURE MANAGEMENT GUIDE: Manual for the Identification & Management of Aquaculture Production Hazards
