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

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

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.

This book was released on 2007 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project investigated the feasibility and cost-effectiveness of several potential early warning approaches for harmful algal blooms at salmon farms in southwestern New Brunswick (SWNB). The components of this 3-yr project included: training farm personnel on the sampling, identification, and counting of harmful algal species; implementation of high frequency phytoplankton monitoring by farm staff at selected salmon farms; retrospective statistical analyses of existing monitoring data; laboratory experiments to determine threshold concentrations of selected harmful algae which can cause problems for farmed salmon; use of a water to predict the movements of blooms which may affect salmon farms; evaluation of the effectiveness of a light sensor array for bloom detection; and evaluation of the usefulness of satellite imagery for bloom detection. Training sessions for farm workers were held in July 2004 and May-June 2005. Training was provided on sampling techniques, the use of microscopes, and the identification and counting of harmful phytoplankton species. Phytoplankton monitoring was conducted by trained staff at four farms near Grand Manan Island in 2004 and at two farms near Grand Manan Island. And one farm in the Passamaquoddy Bay and one farm on the SWNB mainland coast in 2005. The goal was to have farm workers collect and analyze samples approximately daily from late spring to early fall. On average, samples were collected in about 60% of days in 2004 (July-September) and 75% in the 2005 (late May-September), while the numbers of samples analyzed represented

Download or read book Aquaculture and the Environment written by Barbara Sladonja and published by BoD – Books on Demand. This book was released on 2011-12-22 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is the art, science and business of cultivating aquatic animals and plants in fresh or marine waters. It is the extension of fishing, resulted from the fact that harvests of wild sources of fish and other aquatic species cannot keep up with the increased demand of a growing human population. Expansion of aquaculture can result with less care for the environment. The first pre-requisite to sustainable aquaculture is clean wate, but bad management of aquatic species production can alter or even destroy existing wild habitat, increase local pollution levels or negatively impact local species. Aquatic managers are aware of this and together with scientists are looking for modern and more effective solutions to many issues regarding fish farming. This book presents recent research results on the interaction between aquaculture and environment, and includes several case studies all over the world with the aim of improving and performing sustainable aquaculture.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.
