Artificial hatching substrate in the mass rearing of larval Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:30, Working paper, 1984)Eggs from individual Atlantic salmon (Salmo salar) were hatched in a Californian hatching system with and without an astro-turf artificial substrate and growth during the first 200 days following hatching was ... -
Mass production of juvenile Atlantic cod (Gadus morhua L.) in a pond: results and new approaches in 1985
(ICES CM Documents;1985/F:63, Working paper, 1985)Large scale production of juvenile Atlantic cod has been carried out since 1980. A break-through was obtained in 1983 with high survival rates of cod larvae to metamorphosis. This year we have tried to solve two remaining ... -
Report of the Norwegian surveys on blue whiting during spring 1986
(ICES CM Documents;1986/H:53, Working paper, 1986)During the period 12 March-19 April 1986 the blue whiting stock was surveyed by two research vessels in the shelf area from west of Ireland to Lofoten in northern Norway. Maturing blue whiting was still migrating ... -

Causes of variation in carcass traits of Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:25, Working paper, 1984)The aim of the present study was to reveal causes of variation in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon, composed of half sib and full sib groups, ... -

The effect of ambient salinity on the buoyancy of eggs from the Atlantic halibut (Hippoglossus hippoglossus)
(ICES CM Documents;1986/F:52, Working paper, 1986)The effect of ambient salinity on buoyancy and the formation of perivitelline fluid in eggs from the Atlantic halibut Hippoglossus hippoglossus have been investigated. The results clearly demonstrate that the water ... -
The transfer of Atlantic salmon (Salmo salar) with constricted yolk sacs to an artificial hatching substrate
(ICES CM Documents;1985/F:25, Working paper, 1985)Atlantic salmon larvae were transferred from a flat screened hatching tray to an artificial hatching substrate when all larvae had developed yolk sac constrictions. The transfer increased the growth rate and the yolk ... -

Selectivity experiments with square mesh codends in bottom trawl
(ICES CM Documents;1986/B:28, Working paper, 1986)During selectivity experiments with square and diamond mesh codends, an evaluation of the covered codend method and a modified trouser trawl method went in favour of the last one. Both twisted knotless- and braided ... -
Artificial hatching substrate and different time of transfer to startfeeding: Effect on growth and protease activities of the Atlantic salmon (Salmo salar).
(ICES CM Documents;1984/F:22, Working paper, 1984)Groups of Atlantic salmon (Salmo salar) eggs were hatched in a Californian hatching system with and without an astro-turf artificial substrate, and food was presented at four different points in development. Dry weight ... -
Formation of heavy bottom water in the Barents Sea
(ICES CM Documents;1984/C:17, Working paper, 1984)Formation of heavy bottom water through rejection of brine during ide freezing is a regular phenomenon in the Barents Sea, particular on the Novaya Zemlya shelf, but also observed in other shallow localities of the ... -
Effect of swimming on fish target strength
(ICES CM Documents;1985/B:29, Working paper, 1985)The influence of the swimming movement on fish target strength is investigated through a modelling exercise. In this, several gadoid specimens are represented as acoustic scatterers through their triangulated swimbladder ... -
