Comparative electrophoresis of arctic char
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. Electrophoretic patterns of five protein groups from seven geographically isolated populations of Salvelinus alpinus were compared. 2. 2. Muscle protein patterns of S. alpinus, S. aureolus and S. oquassa revealed no interspecific variations. 3. 3.

Mesophilic Composting of Arctic Char Manure
Compost Science & Utilization, 2005Manure in coldwater aquaculture production systems is typically settled in quiescent zones created within raceways to concentrate it prior to being pumped to storage in off-line settling basins. As the water passes through the off-line settling basins, the solids settle out and the excess water is discharged to surface water.

Mercury in Arctic char (Salvelinus alpinus) populations from Greenland
The Science of The Total Environment, 2000Mercury concentrations were determined in muscle tissue of lake resident and anadromous populations of Arctic char in Greenland. Mercury in lake sediment, and in soil and humus from the surrounding area were also determined in the main localities. Fish length and dry weight were shown to be important covariables, which have to be taken into account ...

Bycatch of Loons Assessed in Coastal Arctic Char Fisheries in the Canadian Arctic
North American Journal of Fisheries Management, 2022Abstract Bycatch in fisheries remains one of the biggest conservation threats to seabirds globally, but there has been limited attention given to bycatch in the Arctic. Here, we worked with Inuit commercial fishers in the Cambridge Bay region of Nunavut to record bycatch of birds as part of a fish bycatch reporting initiative, in weir ...

Global Change Biology, 2021
AbstractArctic warming associated with global climate change poses a significant threat to populations of wildlife in the Arctic. Since lipids play a vital role in adaptation of organisms to variations in temperature, high‐resolution mass‐spectrometry‐based lipidomics can provide insights into adaptive responses of organisms to a warmer environment in ...

Arctic char, Salvelinus alpinus .
2002Artic char (Salvelinus alpinus) is a relative newcomer to the aquaculture industry and first impressions were that this would be a highly successful freshwater species because of its ready acceptance by the consumer, the anticipated high price predicted for it relative to its closest competitor, rainbow trout (Oncorhynchus mykiss), and the fact that it

Reconditioning of Arctic char (Salvelinus alpinus) after spawning
Aquaculture, 1993Abstract Resumption of feeding, growth, and pigmentation of sexually mature female Arctic char was accelerated by stripping fish of their eggs. Feed type was a secondary factor in the reconditioning of females, with moist food showing highest acceptance. The rate of reconditioning of males depended solely on feed type (moist feed providing most rapid

Culture of Arctic Char-Possibilities in Norway
Transactions of the American Fisheries Society, 1994Abstract This paper outlines different production strategies for farming Arctic char Salvelinus alpinus in Norway. Economics and marketing are also discussed. Based on recent results, the use of wild Arctic char for smolt production may represent an alternative to intensive smolt production.

Arctic char enter the marine environment before annual ice breakup in the high Arctic
Environmental Biology of Fishes, 2021Mobile consumers often match their movements to short-term resource pulses. In the Arctic, seasonal ice breakup facilitates an ephemeral productivity pulse exploited by marine consumers. The migration of anadromous Arctic char (Salvelinus alpinus) to marine waters occurs around the beginning of ice breakup, but the precise timing of movement is ...

Expression of Three Vitelline Envelope Protein Genes in Arctic Char
General and Comparative Endocrinology, 2001Several studies have shown effects of estrogenic substances on endocrine and reproductive systems in wildlife. Measurement of plasma vitellogenin (VTG) is a commonly used method to determine exposure to estrogenic substances in fish. There is, however, a growing need for additional sensitive and accurate methods to detect estrogenic substances in vivo.
