The construction of a multi-species model for the Barents Sea with special references to the cod-capelin interactions [fra foredrag på "a workshop on comparative biology, assessment and management of gadoids from the North Pacific and Atlantic oceans" 24-28 June, 1985 Seattle, Washington]
(Proceedings: Part III, Conference object, 1986) -
Session 9: Rapporteur's review. Introduction and edited discussion
(Conference object, 1990)Acoustic classification of fish must be one of the few notions in our business that appeals to the popular imagination, both among laymen and non-fisheries scientists. Just estimating fish density by acoustics has been a ... -
Fish behaviour and acoustic sampling
(Conference object, 1990)Fish behaviour may lead in several ways to uncertainties in acoustic abundance estimation. Practical echo-surveying work faces a number of situations where aspects of fish behaviour may be of importance. Unfavourable ... -
Sonar observations of schooling herring: School dimensions, swimming behaviour, and avoidance of vessel and purse seine
(Conference object, 1990)Horizontal dimensions and swimming and avoidance behaviour of herring schools were quantified by means of a multi-beam, true-motion sonar. The schools were usually elliptical with an average length to width ratio of about ... -
Comparative studies of theoretical and empirical target-strength models of euphausiids (krill) in relation to field-experiment data
(Conference object, 1990)The authors considered complete and truncated fluid-sphere models, an approximate fluid-sphere model, complete and truncated fluid finite-length cylinder models, and an empirical model considered as a hybrid fluid bubble/fluid ... -
Fish reaction to trawling noise: The significance for trawl sampling
(Conference object, 1990)The reactions of fish during trawling were observed with a stationary echo sounder as a trawling vessel passed close to the transducer. Several strong, downward avoidance reactions of haddock (Melanogrammus aeglefinus ) ... -
Target tracking with a split-beam echo sounder
(Conference object, 1990)The split-beam technique makes it possible to determine the precise location of a fish in the acoustic beam. This is a very useful feature, as it permits behavioural observations to be conducted without disturbing the fish. ... -
Scientific basis for management of fish resources with regard to seismic exploration
(Fisheries and offshore petroleum exploitation 2nd internationl conference Bergen, Norway,April 6-8, 1992, Conference object, 1992) -
May stocking programs affect the predator stocks and decrease the survival of the wild Atlantic salmon juveniles?
(Conference object, 1997-09-08) -
Dangerously small : Size-dependent mortality of released cod
(Conference object, 1997-09-08) -

(Conference object, 1999) -
Including climate into the assessment of future fish recruitment, using multiple regression models
(Conference object, 2004) -
Will establishment of an introduced red alga result in local biodiversity changes?
(Conference object, 2005-10) -
Pelagic occurence of Greenland halibut (Reinhardtius hippoglossoides) determined from experimental fishing with vertical longlines

(ICES CM documents, Conference object, 2006) -
Harvest Control Rule for Northeast Arctic Saithe: should predation on herring be taken into account?
(Conference object, 2006) -
Can the precision of bottom trawl indices be increased by using simultaneously collected acoustic data? The Barents Sea experience
(ICES CM documents, Conference object, 2006)
