Chang and published by . This book was released on 2006 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Chang and published by St. Andrews, N.B. : Fisheries and Oceans Canada. This book was released on 2005 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

D. Chang and published by St. Andrews, N.B. : Fisheries and Oceans Canada. This book was released on 2005 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Page and published by St. Andrews, N.B. : Fisheries and Oceans Canada. This book was released on 2005 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Salmon Lice written by Simon Jones and published by John Wiley & Sons. This book was released on 2011-08-02 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon louse Lepeophtheirus salmonis is adapted to survive in hostile marine environments of the northern hemisphere, including an ability to parasitize several species of salmon. Salmonids are some of the most economically important and sought after fish for human consumption, and louse parasitism has a significant impact both on cultured and wild fish populations. Salmon Lice is a timely collection of the latest research on the cause and spread of lice infestations and management techniques being designed and implemented to combat this issue. Salmon Lice provides a thorough single volume review of Lepeophtheirus salmonis, the key parasite standing in the way of sustainable and profitable production of salmonid fishes including salmon, trout and charr. Opening with a review of the biology, morphology, life cycle, and larval behavior of the parasite, Salmon Lice proceeds to review the distribution of planktonic larvae of salmon lice, addresses management techniques used in salmonid aquaculture and capture fisheries, provides a practical assessment of the salmon lice issue and explores potential solutions to the problem. With comprehensive coverage of the biology and distribution of this harmful and ubiquitous parasite, Salmon Lice will be of value to fish health researchers, aquaculture and fisheries professionals, and seafood industry personnel to inform the management of both cultured and wild salmonid populations. Key Features: In-depth coverage of a key parasite impacting viability and sustainability of salmonid fisheries and aquaculture Integrates parasite biology and hydrodynamic models in diverse coastal ecosystems Provides a practical assessment of the salmon louse issue Reviews international salmon louse monitoring and management techniques used in salmonid fisheries and aquaculture

Download or read book Use of a Water Circulation Model to Predict the Movements of Phytoplankton Blooms Affecting Salmon Farms in the Grand Manan Island Area Southwestern New Brunswick written by B. D. Chang and published by . This book was released on 2007 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi constituent water circulation model was used to predict the movements of phytoplankton blooms that could affect fish farms in the Grand Manan Island area, Bay of Fundy. Model particles were released from a grid of 659 release point (750 m between adjacent points) around Grand Manan Island. Particles were released from all grid points at 1-h intervals, for a total of 12 releases. Particles were followed for eight tidal cycles (-4 d). We determined which particle tracks intersected each fish farm and the minimum elapsed time between a particle's release and its intersected with a farm. Farms in areas with low velocity currents, such as the Long Island area, were most likely to be affected by blooms originating in the immediate vicinity of the farms. Farms in areas of high-velocity, complex current patterns, such as White Head Island, could be affected by blooms transported from a large area, up to several kilometers away, within 4d.

Download or read book Salmon at the Edge written by Derek Mills and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmon at the Edge covers, in depth, the problems faced by wild Atlantic salmon and sea trout in estuaries and coastal zones, and in their early weeks at sea. The book also reflects the current precarious state of many migratory salmonid populations and the need for new approaches to a number of threats to these populations. Generated from papers given at the landmark Sixth Atlantic Salmon Symposium, held in Edinburgh, UK, Salmon at the Edge contains a huge wealth of information on such important topics as the impact of salmon farming, the behaviour of post-smolts in their early migration and their vulnerability to by-catch, and the use of nutrient enrichment and habitat enhancement to increase production of juvenile salmonids. With chapters written by internationally-known and respected authors, and including a message of support from His Royal Highness The Prince of Wales, this important volume is essential reading for all those involved with salmonid fishes, including fish biologists, fisheries scientists and managers, environmental, marine and freshwater scientists, and personnel involved in salmon aquaculture. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. The Sixth Atlantic Salmon Symposium, from which chapters in this book have been generated, was organised by The Atlantic Salmon Trust and The Atlantic Salmon Federation, and was published with the financial support of The Fishmongers’ Company and Scottish and Southern Energy. Derek Mills of The Atlantic Salmon Trust, Pitlochry, Perthshire, UK has many years of research, writing and editing experience in salmon biology and fisheries
