Migratory patterns of escaped farmraised Atlantic salmon
(ICES CM Documents;1990/F:55, Working paper, 1990)Simulated escapes of farmed salmon from netpens are done. Migratory behaviour and routes are studied by combining acoustic tagging and standard tagging - release methodology. A prototype of a recapture trap has been ... -
Smoltification of Atlantic salmon in different water qualities and subsequent growth in sea water, following distinct transfer strategies from freshwater
(ICES CM Documents;1990/F:64, Working paper, 1990)Atlantic salmon parr were kept in four different fresh water qualities for seven months before smoltification, which was characterized by plasma chloride content after sea water challenge tests. Three groups were transferred ... -

(ICES CM Documents;1990/K:2, Working paper, 1990)A large scale spring release of juvenile lobsters, Homarus gammarus, was conducted at Kvitsøy, southwestern Norway in March 1990. The lobsters, 14,700 one and a half year old and 8,700 six months old, were tagged internally ... -
Spawning strategy and a mechanism for adaptive larval production in Arcto-Norwegian cod
(ICES CM Documents;1990/L:100, Working paper, 1990)The Arcto-Norwegian cod is spawning in the temperature stable Atlantic water, and the eggs ascend into the more temperature variable coastal water. Changes in time of peak spawning, up to 10 days within the last 60 ... -
A preliminary study of microstructure in otoliths of seacaught mackerel (Scomber scombrus L.) larvae
(ICES CM Documents;1990/H:4, Working paper, 1990)Mackerel larvae have been sampled during two cruises south of lrland, in May and June 1989 and preserved in ethanol. The microstructure of the otoliths (sagittae) from the mackerel larvae have been examined. There is a ... -
Diet of polar cod, Boreogadus saida, in the Barents Sea related to fish size and geographical distribution
(ICES CM Documents;1990/G:48, Working paper, 1990)Polar cod stomachs collected during autumn of 1986-1988 in the Barents Sea were analysed. The results indicated that polar cod is an opportunistic feeder, and that the observed changes in feeding pattern from one region ... -
