The Handbook of Salmon Farming
Author: Selina M. SteadPublisher: Springer Science & Business Media
ISBN: 9781852331191
Category : Nature
Languages : en
Pages : 544
Book Description
Over the past few years, there has been significant growth and development in the salmon farming industry. In order to be successful, practitioners not only need to know how the salmon lives and survives in the wild but, amongst other things have knowledge of disease, production processes, economics and marketing. The Handbook of Salmon Farming is a practical guide that covers everything the practitioner needs to know, and will also be of great use to academics and students of aquaculture and fish biology. The editors have invited contributions from experts in academia, the fish industry and government to provide an up-to-date and comprehensive handbook.
Salmon Wars

Category : Health & Fitness
Languages : en
Pages : 226
Book Description
A Pulitzer Prize-winning correspondent and a former private investigator dive deep into the murky waters of the international salmon farming industry, exposing the unappetizing truth about a fish that is not as good for you as you have been told. A decade ago, farmed Atlantic salmon replaced tuna as the most popular fish on North America’s dinner tables. We are told salmon is healthy and environmentally friendly. The reality is disturbingly different. In Salmon Wars, investigative journalists Douglas Frantz and Catherine Collins bring readers to massive ocean feedlots where millions of salmon are crammed into parasite-plagued cages and fed a chemical-laced diet. The authors reveal the conditions inside hatcheries, where young salmon are treated like garbage, and at the farms that threaten our fragile coasts. They draw colorful portraits of characters, such as the big salmon farmer who poisoned his own backyard, the fly-fishing activist who risked everything to ban salmon farms in Puget Sound, and the American researcher driven out of Norway for raising the alarm about dangerous contaminants in the fish. Frantz and Collins document how the industrialization of Atlantic salmon threatens this keystone species, endangers our health and environment, and lines the pockets of our generation's version of Big Tobacco. And they show how it doesn't need to be this way. Just as Eric Schlosser’s Fast Food Nation forced a reckoning with the Big Mac, the vivid stories, scientific research, and high-stakes finance at the heart of Salmon Wars will inspire readers to make choices that protect our health and our planet.

Interactions Between Sea Lice (Lepeoptheirus Salmonis and Caligus Clemensii), Juvenile Salmon (Oncorhynchus Keta and Oncorhynchus Gorbuscha) and Salmon Farms in British Columbia

Book Description
The issue of sea lice (Lepeoptheirus salmonis and Caligus clemensii) transfer from salmon farms to wild salmon is a controversial topic in British Columbia (BC). A series of sea lice epizootics (four in five years) on juvenile chum (Oncorhynchus keta) and pink (0. gorbuscha) salmon in the Broughton Archipelago (BA), an area with the highest density of salmon farms on the west coast, have caused significant concern among conservationists, local First Nations, and the general public over the possible impacts of salmon farms on wild salmon. Key to the debate has been a lack of data on ambient sea lice infection rates on juvenile salmon in the absence of the influence of salmon farms. This work represents one of the first attempts to empirically examine ambient sea lice infection rates on juvenile salmonids. Objectives were to test hypotheses including: geographic variability is a significant factor in sea lice population dynamics, ambient sea lice infection rates on juvenile salmon are low, juvenile salmon susceptibility to sea lice infection, and the influence of salmon farms on ambient sea lice infection rates. Over a three year period, samples of juvenile chum and pink salmon (n=13.874) were collected using a beach seine net in the central coast of British Columbia (Klemtu/Bella ivBella), a vast area with limited salmon farming activity. and with geography that allowed for simultaneous assessment in the same region of the natural interaction between sea lice and juvenile salmon and the influence of salmon farms on the interaction. Sampling was also conducted in other areas without salmon farms (Southern Gulf Islands: n=3847) and with salmon farms (Broughton Archipelago; n=3911). The results of the field experiments were also used in conjunction with laboratory experiments to examine the susceptibility of juvenile chum vs. pink salmon to infection by sea lice. The ambient lice infection rates for juvenile chum and pink salmon were up to 32% prevalence, less than one louse per fish and less than two lice per gram (prevalence: 2.0 (1.0) - 32.0 (19.0), mean lice per fish: 0.02 (0.01) - 0.67 (0.22), mean lice per gram: 0.56 (0.08) - 1.93 (0.13)). This result was found to be consistent across geographic areas with no salmon farming activity suggesting that geographic variability was not a significant factor in the natural interaction between sea lice and juvenile salmon. Salmon farms were found to strongly influence the relationship between sea lice and juvenile chum and pink salmon. Sea lice infection rates of juvenile salmon collected near salmon farms were significantly higher than non-salmon farming regions ranging from 3 - 150 times higher in the BA and from 2 - 14 times higher in the Klemtu region. Infection levels near salmon farms were variable in intensity from year to year. The extent to which the sea lice-salmon relationship was affected by salmon farms was dependent on farmed species, farm location, within year variability in fish size, and the scale of salmon farming activities within the region. The results from the laboratory and field studies demonstrate that juvenile chum salmon were more susceptible to infection by sea lice than juvenile pink salmon. However, the exact mechanism for the observed differences was not identified. Possible reasons for the observed differences could be related to genetically determined susceptibility, fish mucous differences, lethal lice infection tolerances. or other factors not examined. The results of this study suggest that the elevated sea lice infection rates observed in the BA and other areas present a significant risk to the health of wild salmon and that salmon farms are the most likely cause based on the biology and ecology of sea lice. In order to better understand the potential for salmon farms to affect wild salmon populations, it is suggested that investigations into farm level sea lice contributions be conducted in the BA and other areas where salmon farms operate. In addition, investigation into the lethal lice infection rates for juvenile salmon at early marine life size should also be conducted.

Book Description
This report provides records of the peer review meeting for the evaluation of the state of current knowledge regarding the interactions between wild & farmed Atlantic salmon in the Maritime Provinces. During the five-day session, 19 working papers were peer reviewed and the comments & concerns, along with author responses, are summarized in the rapporteur reports prepared for each paper. These reports include detailed research & management recommendations for immediate & long-term action in each specific case. Topics of papers include: the salmon aquaculture industry in the Maritimes and Maine; the status of wild Atlantic salmon stocks in the Maritimes; aquaculture escapees & occurrence in rivers of the Maritime Provinces; genetic & other impacts of escaped salmon; breeding programs for performance improvement of Atlantic salmon; fish disease agents in cultivated & wild salmon; ecological & behavioural interactions between farmed & wild salmon; regulations & policies to control & minimize negative impacts from aquaculture on wild salmon stocks; options for farmed salmon containment; and disease control in farmed salmon.
