The project's main goal was to enhance understanding of the water circulation and water transport pathways within the Long Pond Bay area of southern Grand Manan and to use this to help assess the influence of the water circulation pattern on fish health and bay management concerns in the area. This report summarizes the project's findings. It also includes the presentations given at the final meeting of the project, held on February 17, 2004.--Publisher's description.

Published in Cooperation with THE WORLD AQUACULTURE SOCIETY Aquaculture loses millions of dollars in revenue annually due to aquatic animal diseases. Disease outbreaks continue to threaten profitable and viable aquaculture operations throughout the world. As a result, aquaculture biosecurity programs that address aquatic animal pathogens and diseases have become an important focus for the aquaculture industry. Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease provides valuable information that will increase success in combating infectious aquatic disease. Key representatives of international, regional, and national organizations presented their views on this important issue as part of a special session at the 2004 World Aquaculture Society Annual Conference. The chapters of this book cover a wealth of experience from the varied perspectives of these experts on biosecurity, policies, and measures to take the offensive against the spread of diseases in aquatic animals. With contributions from renowned international experts, covering approaches to biosecurity policies and measures currently practiced, Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease is a vital reference for all those concerned about protecting aquaculture from impacts of aquatic animal disease.

Successfully managing fish health issues associated with fish farming is an important aspect for the sustainability of aquaculture. Diseases such as infectious salmon (Salmo salar) anaemia (ISA) are major issues facing the salmon aquaculture industry in many locations around the world. One mechanism that may facilitate the spread of the ISA virus between farms is the water-borne transport of viral particles. In an effort to help estimate the potential for water exchange of the ISA virus in the southwestern New Brunswick area of the Bay of Fundy, a three-dimensional tidal water ciculation and particle transport model was developed for the southern area of Grand Manan Island. Water exchange scenarios based on the movement of particles from a fish farm during one tidal excursion, as predicted by the model, are compared to those estimated by a simple method assuming a 5-km radius circular zone of water exchange around each farm. The results can be used to estimate scenarios of viral transport and dispersal for use in fish health management, farm site selection and the designation of Bay Management Areas

Infectious salmon anemia (ISA) was first detected in salmon farms of southwestern New Brunswick in 1996 and in adjacent Cobscook Bay, Maine in 2001. There was speculation that the virus may have been transmitted through the water between farms in the two jurisdictions. In an effort to help estimate the potential for water exchange of the ISA virus between farms in Cobscook Bay and adjacent areas of southwestern New Brunswick, a three-dimensional tidal water circulation and particle transport model was used. Water exchange scenarios based on the movement of particles during one tidal excursion, as predicted by the model, are compared to those estimated by a simple method assuming a 5-km radius circular zone of water exchange around each farm

Infectious salmon anemia (ISA) was first detected in salmon farms along the mainland shore of southwestern New Brunswick in 1996-1998 and in farms in the adjacent western Deer Island area in late 1998. Farms in both areas have been reinfected in subsequent years and there has been speculation that the virus may have been transmitted through the water between the mainland and Deer Island farms. In an effort to help estimate the potential for water exchange of the ISA virus between farms in these areas, a 3-dimensional tidal water circulation and particle transport model were used. Water exchange scenarios based on the movement of particles during one tidal excursion, as predicted by the model are compared to those estimated by a simple method assuming a 5-km radius circular zone of water exchange around each farm. The effectiveness of removing certain farms in order to create a separation zone between mainland and Deer Island farms was also examined

Infectious salmon anemia (ISA) was first detected in salmon farms in southwestern New Brunswick in 1996. In an effort to help estimate the potential for water-borne exchange of the ISA virus among farms in this area, we used a three-dimensional tidal water circulation and particle transport model. Water exchange scenarios based on the movement of particles during one tidal excursion, as predicted by the model, are compared to those estimated by a simple method assuming a 5-km radius circular zone of water exchange around each farm. In this report, we examined the water exchange among farms in the Passamaquoddy Bay area, as well as with farms in adjacent areas. We also examined the relative risks, with respect to the water-borne spread of disease, of two potential locations for a proposed new salmon farm in northern Passamaquoddy Bay
