Vaccination of Arctic char (Salvelinus alpinus) against vibriosis
(ICES CM Documents;1988/F:13, Working paper, 1988)Arctic char of six different strains have been vaccinated against vibriosis and a relative protection (RPP) of 98% was demonstrated by waterborne challenge. This species is highly susceptible to vibriosis and the gross ... -

Comparative analysis of split beam data
(ICES CM Documents;1988/B:44, Working paper, 1988)Split beam data can provide high quality, in situ, fish target strength estimates, however a careful calibration is required to realize this potential. In same cases a standard target has been used to make a large number ... -
Seawater adaptability of two strains of arctic char (Salvelinus alpinus) reared under different light regimes
(ICES CM Documents;1987/F:37, Working paper, 1987)Groups of Arctic char (Salvelinus alpinus) were reared under three experimental light regimes. Two different strains of char were used, one non-migratory from south Norway, the other anadromous from northern Norway. All ... -
Distinguishing between spring and autumn spawned herring from daily increments, a preliminary report
(ICES CM Documents;1988/H:15, Working paper, 1988)Otoliths from Norwegian Spring Spawning herring larvae, collected on a cruise in May 1985 and North Sea Autumn Spawned herring larvae, collected on a cruise in Desember 1987, were examined for daily increments. A greater ... -
A stripping method for Atlantic halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1987/F:40, Working paper, 1987)A stripping-board was built and tested on a broodstock of halibut ranging from 8 to 150 kg body weight. The smooth surface of the neophrene mattress minimized the loss of mucus and reduced the stripping stress ... -
The migration of coastal cod (Gadus morhua L.) tagged in a fjord of western Norway
(ICES CM Documents;1988/G:5, Working paper, 1988)This study is part of a research program investigating the possibility of enhancing the production of coastal cod via a large scale release of pond produced fish in Masfjorden, a fjord of western Norway. An analysis of ... -
Diurnal changes in bottom trawl catches and vertical fish distribution
(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 ... -
Full scale fishing trials for tusk (Brosme brosme) and cod (Gadus morhua) with a collapsible fish trap
(ICES CM Documents;1988/B:33, Working paper, 1988)A collapsible fish trap with low weight and low stacking volume has been developed and tested in full scale fishing operations. The catch rates of tusk were promising, while the catches of cod were too low and variable ... -

Automatic recording of fish heart rate on a personal computer
(ICES CM Documents;1988/B:34, Working paper, 1988)From acoustic tags operated into fish in a closed system, the heartbeat signals are sent via underwater telemetry and counted on a personal computer. The computer removes false pulses caused by noise, and calculates the ... -
