Preliminary report on the effects of temperature on the development of eggs and larvae of halibut (Hippoglossus hippoglossus) and on the bacterial population in the incubators
(ICES CM Documents;1989/F:19, Working paper, 1989)Eggs were stripped from one female of the halibut broodstock at Austevoll Aquaculture Station, and fertilised with sperm from two males immediately before incubation. Eggs were held in nine open-circulation 250 l incubators ... -

The egg production and spawning stock size of the North Sea mackerel and horse mackerel stocks in 1988
(ICES CM Documents;1989/H:16, Working paper, 1989)During the period 5 April to 28 July 1988 the spawning areas of North Sea mackerel and horse mackerel were investigated by research vessels from the Netherlands, Denmark and Norway. Based on the plankton samples ... -
Migration of western mackerel to the North Sea 1973 - 1988
(ICES CM Documents;1989/H:20, Working paper, 1989)The latest years, it is evident that most of the mackerel present in the North Sea belongs to the Western stock, since the yearly catches by far exceed the presumed size of the North Sea stock. The Norwegian tagging ... -
Density driven currents in the Barents Sea calculated by a numerical model
(ICES CM Documents;1989/C:20, Working paper, 1989)A baroclinic, 3-D model is described. It is adapted to a Barents Sea situation in order to simulate the currents in this area. The model is of a so-called level type which contains fixed, but permeable levels. It also ... -
How can a potential oil pollution affect the recruitment to fish stocks?
(ICES CM Documents;1989/Mini:5, Working paper, 1989)Eggs, larvae and the larvae's first search for food are the most critical stages in a fish life, both to threats from natural causes and pollution. Based on experimental studies of several species of fish eggs, larvae ... -

Wideband beam pattern
(ICES CM Documents;1989/B:2, Working paper, 1989)Transducer directivity is important in the basic acoustic surveying methods of echo counting and integration. In quantifying the directivity, the beam pattern is often computed assuming ideal single-frequency operation. ... -

Spheres for calibrating an eleven-frequency acoustic measurement system
(ICES CM Documents;1989/B:3, Working paper, 1989)Calibration of a single resonant transducer by standard sphere is a simple matter. How does one calibrate an array composed of eleven different resonant transducers spanning the frequency range from 27 to 710 kHz? A ... -
Empirical results on precision - effort relationships for acoustic surveys
(ICES CM Documents;1989/B:30, Working paper, 1989)Repeated echo integrator surveys using a rather dense survey grid were performed in areas where the effect of fish migration was assumed to be insignificant. Relative estimates of fish abundance representing different ... -
