Qualitative and quantitative behaviour studies in starving and feeding turbot (Scopthalmus maximus L.) larvae
(ICES CM Documents;1985/F:38, Working paper, 1985)A computer aided video system was used to register three dimensional movement and behaviour patterns in starving and feeding turbot larvae. The feeding larvae were kept and were monitored beyond metamorphosis in the ... -
Radioactive contamination in the Barents Sea, past and present status, uptake of radinuclides in fish and its impact on fisheries
(ICES CM Documents;1994/E:16, Working paper, 1994)During the atmospheric nuclear bomb test at the end of the fifties and in the beginning of the sixties the Institute of Marine Research, IMR, monitored the radioactive contamination in commercial landed fish from the ... -
Reactions of herring to trawling noise
(ICES CM Documents;1988/B:36, Working paper, 1988)The reaction of herring during pelagic trawl sampling has been studied by use of a high-frequency scanning sonar mounted on the headline of the trawl. The difficulties of obtaining high catch rates on shallow herring ... -
Reappearance of Norwegian spring spawning herring on spawning grounds south of 60°N
(ICES CM Documents;1989/H:22, Working paper, 1989)In spring 1989 herring spawned west of Karmøy (near Haugesund) on the Norwegian west coast. Prior to 1945 the coastal areas around Haugesund were among the most important spawning (and fishing) grounds of the Norwegian ... -
Recatches of marked lobster, Homarus gammarus, released in 1988
(ICES CM Documents;1991/K:7, Working paper, 1991)A pilot scale release of juvenile lobsters, Homarus gammarus, was conducted at Austevoll, western Norway in August 1988. One and two year old lobsters were marked with a brand on either the carapace or the tail. The two ... -
Recent age compositions and aberrant migration patterns of the Barents Sea stock of harp seals Phoca groenlandica
(ICES CM Documents;1996/N:4, Working paper, 1996)Since 1978, and in particular in 1986-1988, large numbers of harp seals Phoca groenlandica have invaded coastal waters of North Norway during winter and spring. After 1988 the harp seal invasions have been restricted to ... -
Recent migration routes of Norwegian spring spawning herring
(ICES CM Documents;1992/H:18, Working paper, 1992)The migration routes of Norwegian spring spawning herring have changed considerably during the last decades. In the 1950s and beginning of the 1960s the stock spawned off the west coast of Norway in late winter, were ... -
Recent studies of the distribution and abundance of grey seals (Halichoerus grypus) in north Norway, and their possible influence on parasitic infestations in fish
(ICES CM Documents;1991/N:2, Working paper, 1991)Distributions of grey seals Halichoerus grypus were studied during aerial and ground surveys in North Norway. Surveys were conducted from Lofoten to the Soviet border during the moult (March-April, Finnmark) and breeding ... -
Recent upper layer cooling and freshening in the Norwegian Sea
(ICES CM Documents;1996/C:7, Working paper, 1996)Several time series of temperature and salinity in the Norwegian Sea indicate a general upper layer decrease in both variables. The observations indicate that this change began in about the middle of the 1960s. Time ... -
Recent variations in recruitment of Northeast Atlantic greenland halibut (Reinhardtius hippoglossoides) in relation to physical factors
(ICES CM Documents;1997/EE:6, Working paper, 1997)Based on annual bottom trawl surveys in the Barents Sea and Svalbard area in 1983-96, the paper describes variations in abundance and composition of 1-group Greenland halibut (Reinhardtius hippoglossoides). The main ... -
Recruitment indices of Norwegian spring-spawning herring for the period 1965 -1984 based on the international 0-group fish surveys
(ICES CM Documents;1985/H:54, Working paper, 1985)The trawl data from the International 0-group fish surveys in the Barents Sea are analyzed. The fishing powers of the participating vessels are estimated and corrected for. A relative index of year class strength is ... -
Recruitment of wild and artificially reared cod (Gadus morhua L.) to the local spawning stock
(ICES CM Documents;1987/F:27, Working paper, 1987)A stock enhancement study of coastal cod was initiated in 1983, when 19,002 artificially reared cod fry were tagged and released in the Austevoll region in western Norway. As a part of this program, 3,946 cod fry were ... -
Recruitment variability in Norwegian spring-spawning herring (Clupea harengus L.): the effect of temperature in larval drift trajectories
(ICES CM documents, Working paper, 2000)During late winter, the Norwegian spring-pawning (NSS) herring migrate southward along the Norwegian coast to spawn in March-April. The larvae drift northwards in the Norwegian coastal current during their first months and ... -
Reduced oxygen concentrations in herring wintering areas
(ICES CM Documents;1992/H:16, Working paper, 1992)Since 1987 the major part of the adult Norwegian spring spawning herring stock has been wintering in the Ofotfjord and the Tysfjord, two tributaries to the Vestfjord in northern Norway. The herring enter the fjords in ... -
Regional dynamics of Calanus in the Norwegian Sea in response to ocean climate in 1997
(ICES CM Documents;2000/M:20, Working paper, 2000)A coupled 3D hydrodynamic and ecological model has been set up for the Norwegian Sea (i.e. SINMOD). The hydrodynamic model uses the z-coordinates in the vertical direction. The horizontal grid point distance is 6.67 km ... -
