A multiple approach to behaviour studies of salmon reared in marine net pens
Fernö, Anders; Furevik, Dag M.; Huse, Ingvar; Bjordal, Åsmund (ICES CM Documents;1988/F:15, Working paper, 1988)The behaviour of Atlantic salmon in culture was lnvestigated by various techniques with the ultimate goal of characterlzing the behaviour typical for a situation with rapid growth. Differences in behaviour between and ... -
A preliminary Investigation on Shelf Edge and Deepwater Fixed Net Fisheries to the West and North of Great Britain, Ireland, around Rockall and Hatton Bank.
Hareide, Nils Roar; Rihan, Dominic; Mulligan, Myles; McMullen, Philip; Garnes, Greta; Clark, Maurice; Connolly, Paul; Tyndall, Peter; Misund, Robert; Furevik, Dag M.; Newton, Andrew; Høydal, Kjartan; Blasdale, Tom; Humborstad, Odd-Børre (ICES CM documents;2005/ N:07, Working paper, 2005)Since the mid-1990s, a fleet of up to 50 vessels have been conducting a gillnet fishery on the continental slopes to the West of the British Isles, North of Shetland, at Rockall and Hatton bank. These vessels, though ... -
Catches of Greenland halibut (Reinhardtius hippoglossoides) in ghost fishing gillnets on the Norwegian continental slope
Humborstad, Odd-Børre; Furevik, Dag M.; Løkkeborg, Svein; Hareide, Nils Roar (ICES CM Documents;2000/J:8, Working paper, 2000)Catches in deliberately “lost” gillnets were studied during a ten-day cruise conducted at Storegga 70 nm off the coast of mid-Norway in July 2000. Gillnet fleets were deployed at depths of between 537 and 677 m, and soak ... -
Effects on salmon (Salmo salar) from different operational procedures in fish farming
Bjordal, Åsmund; Fernö, Anders; Furevik, Dag M.; Huse, Ingvar (ICES CM Documents;1988/F:16, Working paper, 1988)The effects on farmed salmon caused by operational procedures as handling, de-lousing, removal of dead fish, grading and transfer were studied by underwater TV-observations, ultrasonic telemetry of heart rate and analyses ... -
Full scale fishing trials for tusk (Brosme brosme) and cod (Gadus morhua) with a collapsible fish trap
Bjordal, Åsmund; Furevik, Dag M. (ICES CM Documents;1988/B:33, Working paper, 1988)A collapsible fish trap with low weight and low stacking volume has been developed and tested in full scale fishing operations. The catch rates of tusk were promising, while the catches of cod were too low and variable ... -
Migratory patterns of escaped farmraised Atlantic salmon
Furevik, Dag M.; Rabben, Håvard; Mikkelsen, Kent Olav; Fosseidengen, Jan Erik (ICES CM Documents;1990/F:55, Working paper, 1990)Simulated escapes of farmed salmon from netpens are done. Migratory behaviour and routes are studied by combining acoustic tagging and standard tagging - release methodology. A prototype of a recapture trap has been ... -
Reduced bycatch of red king crab (Paralithodes camtschatica) in the cod gillnet fisheries in northern Norway: Fishing trials with norsel mounted gillnets
Godøy, Hallvard; Furevik, Dag M.; Løkkeborg, Svein (ICES CM documents, Working paper, 2000)Bycatch of red king crab (Paralithodes camtschatica) in stationary fishing gears, q&ally gillnets, is an increasing problem to the inshore fishermen in the northern part of Norway (Finnmark county). The results are large ... -
Surface activity of Atlantic salmon (Salmo salar) in net pens
Furevik, Dag M.; Huse, Ingvar; Bjordal, Åsmund; Fernö, Anders (ICES CM Documents;1988/F:19, Working paper, 1988)An important feature of the behaviour of salmon is the leaping and rolling activity. These surface activities were studied in fish in net pens in relation to environmental factors and operational procedures. Data were ... -
The effect of shading in pen rearing of Atlantic salmon (Salmo salar)
Huse, Ingvar; Bjordal, Åsmund; Fernö, Anders; Furevik, Dag M. (ICES CM Documents;1988/F:18, Working paper, 1988)A full scale pen rearing experiment with covers to reduce illumination was carried out. No significant effects were observed on growth, mortality, ectoparasite infection, maturation or net pen fouling.
