The annual global production of farmed salmon has increased by a factor of 40 during the past two decades. Salmon from farms in northern Europe, North America, and Chile are now available widely year-round at relatively low prices. Salmon farms have been criticized for their ecological effects, but the potential human health risks of farmed salmon consumption have not been examined rigorously. ...

This study compared the flesh quality of farmed and wild sources of British Columbia (BC) salmon with respect to concentrations of polychlorinated biphenyl compounds, polychlorinated dibenzodioxins/dibenzofurans and their associated toxic equivalents, total mercury (THg), methylmercury (MeHg), and selected fatty acids of known importance for human health viz., omega-3 (n-3) highly unsaturated f...

A plasmacytoid leukemia (PL) has caused mortalities in chinook salmon (Oncorhynchus tshawytscha) reared in seawater netpens in western British Columbia, Canada, since 1988. Kidney or eye tissues from 11 of 13 fish from netpens with clinical PL had reverse transcriptase (RT) activity. This RT activity was associated with virus particles of retrovirus morphology and buoyant density. In a transmis...

This study focuses on understanding the temporal variability in hydrological and thermal conditions in a small mountain stream and its potential implication for two life stages of Atlantic salmon (Salmo salar) – stream resident juveniles and returning adult spawners. Stream discharge and temperature in the Girnock Burn, NE Scotland, were characterised over ten hydrological years (1994/1995–2003...

Fish are an important source of the n-3 highly unsaturated fatty acids (HUFA), 1 eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids that are crucial to the health of higher 2 vertebrates. The synthesis of HUFA involves enzyme-mediated desaturation, and a ∆5 fatty acyl 3 desaturase cDNA has been cloned from Atlantic salmon (Salmo salar) and functionally 4 characterized previously. Here we re...

Threatened fish populations worldwide are relying on stock supplementation by hatchery-reared fish. Although stocking with non-native may lead to hybridization, thereby disrupting local adaptations, it could also improve the adaptive potential of small increasing variability in essential behavioral traits. In this study, we crossbred critically endangered Finnish landlocked salmon a geographica...

(2013) Effect of dietary digestible energy content on expression of genes of lipid metabolism and LC-PUFA biosynthesis in liver of Atlantic salmon (Salmo salar L.) NOTICE: this is the author's version of a work that was accepted for publication in Aquaculture. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality contr...

Infectious Salmon Anemia virus (ISAv) poses a serious threat to fish farmers in Canada and globally. It can cause significant economic losses to Atlantic Salmon farming operations, and is a potential risk to wild Atlantic Salmon populations. Although improved farming and management practices have helped reduce the risk and impact of the disease, further outbreaks associated with new virulent st...

The bioavailability of Se from raw and cured selenomethionine-enriched (Se-enriched) salmon fillets was assessed in Se-deficient male albino rats (Mol: Wist). A low-Se Torula yeast feed was supplemented with 0, 50, 100, 150 or 200 microg Se/kg as sodium selenite or as Se from raw or cured Se-enriched salmon. The diets were fed to weanling rats for 10 and 30 d. Bioavailability of Se was assessed...

The Skokomish salmon processing plant was built to provide a more efficient system for handling fish from the Indian commercial fishery on the Skokomish River. It is located on the Olympic Peninsula near the mouth of the Skokomish River about 45 miles southwest of Seattle, Washington (Figure 1). processing plant was designed in 1971, constructed in 1972, and has been in operation since December...
