A new radio link telemetry positioning system, experiences from tracking of fish and crustaceans
Bjordal, Åsmund; Engås, Arill; Soldal, Aud Vold; Øvredal, Jan Tore (ICES CM Documents;1993/B:23, Working paper, 1993)Telemetry positioning systems based on hydrophone arrays have been used for different tracking applications. The main improvement of this new system is the wire-less transmission of signals from hydrophone - radio buoys ... -
Ansvarlig fangststrategi
Soldal, Aud Vold (Fisken og havet, Research report, 1996)Responsible catch strategy or sustainable utilization of the resources in harmony with the environment, must be based on the following criteria: optimum size selection, optimum species selection, minimum discard, minimum ... -
Avoidance reactions of ultrasonic tagged cod during bottom trawling in shallow water
Engås, Arill; Soldal, Aud Vold; Øvredal, Jan Tore (ICES CM Documents;1991/B:41, Working paper, 1991)Introduction: Observations made by echo sounder (Ona 1988) have shown that cod (Gadus morhua L.) may avoid an approaching survey vessel horizontally and vertically. However, there has been a lack of information on the ... -

Catch comparison between rockhoppers and bobbins ground gear on the Norwegian bottom sampling trawl
Engås, Arill; Jacobsen, Jan Arge; Soldal, Aud Vold (ICES CM Documents;1988/B:31, Working paper, 1988)In a study aimed at improving the reliability of the Norwegian bottom sampling trawl, comparative fishing between standard bobbins gear and rockhopper ground gear were carried out in the Barents Sea. The catch ratios ... -
Coastal consentrations of 0-group NE-Artic cod. [HELP 24]
Olsen, Steinar; Soldal, Aud Vold (help, Research report, 1989)Investigations in 1987 and 1988 aimed at catching and utilizating wild cod fry as seed fish in commercial aquaculture have demonstrated that, at the time of year when the main brood of the year is drifting pelagically ... -
Diurnal changes in bottom trawl catches and vertical fish distribution
Engås, Arill; Jacobsen, Jan Arge; Soldal, Aud Vold (ICES CM Documents;1988/B:32, Working paper, 1988)Bottom sampling trawl catches and acoustic abundance estimates of North-East Arctic cod and haddock in the Barents Sea were collected and examined according to time of day. The trawl catches were at average larger by day ... -
Effects of fishing strategy on relative selectivity in trawls, longline and gillnets
Huse, Irene; Løkkeborg, Svein; Soldal, Aud Vold (ICES CM Documents;1996/B:23, Working paper, 1996)Exploitation of fish stocks is dependent on effort, catchability, the selectivity of the gear used, and the fishermen's choice of time and place. A full-scale fishing experiment was conducted in February 1996 at the coast ... -
Effects of seismic shooting on catch and catch-availability of cod and haddock

Effects of seismic shooting on local abundance and catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
Engås, Arill; Løkkeborg, Svein; Ona, Egil; Soldal, Aud Vold (Journal article; Peer reviewed, 1996)To determine whether seismic exploration affected abundance or catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), acoustic mapping and fishing trials with trawls and longlines were conducted in the ... -

Hoveddelen ble utført ved Albuskjell 2/4 Fox ... -
Evidence of sampling induced biases in mortality estimates from experiments investigating mortality in fish escaping from towed fishing gears
Breen, Mike; Sangster, Graham; O’Neill, Barry; Kynoch, Rob; Jones, Emma; Soldal, Aud Vold (ICES CM Documents;2002/V:25, Working paper, 2002)When studying escapes from trawl codends and other selective devices, the most common method of capturing or ‘sampling’ escaping fish is using a codend cover (Figure 1). This paper will summarise a programme of work providing ... -
