Observations on the Depth Range of tagged Bluefin Tuna (Thunnus thynnus L.) based on Pressure Marks on the Lea Tag
(ICES CM Documents, Working paper, 1964)The present paper is an investigation on the depth range of tagged bluefin tuna based on pressure marks on the Lea tag (Figure 1). It was observed that the within season recaptures were without pressure marks, while the ... -
Observations on the embryonic development of capelin (Mallotus villosus MÜLLER) from the Barent Sea
(Fiskeridirektoratets skrifter, serie havundersøkelser;vol 18, no. 2, Research report, 1986)The embryonic development of the Barents Sea capelin is described, with emphasis of characteristic features which can be applied in the ageing of eggs. The development is described for three different temperatures observed ... -

Observer program for juvenile Northeast Arctic saithe
(Working paper, 2010-02)NEA saithe 0-group indices from observers along the coast does not seem to reflect the dynamics in year class strength very well and is therefore probably not suitable for improving future recruitment estimates for this stock. -

Observing individual fish behavior in fish aggregations: Tracking in dense fish aggregations using a split-beam echosounder
(Journal article; Peer reviewed, 2007)Acoustic instruments are important tools for observing the behavior of aquatic organisms. This paper presents a simple but efficient method for improving the tracking of closely spaced targets using a split-beam echosounder. ... -
