A preliminary review of the joint investigations on the distribution of herring in the Norwegian and Iceland Seas 1950- 1970
(ICES CM Documents;1996/H:14, Working paper, 1996)The paper reviews the joint international investigation of the distribution of the Atlanto-Scandian herring in relation to temperature during the period prior to the collapse of the stock in the late 1960s. The results ... -
The relationship between the location of western mackerel spawning, larval drift and recruit distributions: A modelling study
(ICES CM Documents;1996/S:33, Working paper, 1996)Summary: Mackerel spawning distributions have changed over the last 20 years. From 1977-1995 there has been a progressive westerly shift in the distribution of spawning in May/June (peak spawning), with a resultant ... -

Initial collateral measurements of some properties of Calanus finmarchicus
(ICES CM Documents;1996/L:21, Working paper, 1996)In general, acoustic quantification of zooplankton such as Calanus finmarchicus requires the use of models, among other reasons, to aid in the interpretations of data collected on animals whose scattering properties change ... -
Recordings of mature Gonatus fabricii (Lichtenstein) off the Norwegian coast
(ICES CM Documents;1996/K:17, Working paper, 1996)Two mature female and three mature males were sampled by trawling with a pelagic trawl at depths of more than 800 m off northem Norway. A third female were sampled with bottom trawl at 970 m off mid Norway. The females ... -
Migration behaviour of Norwegian spring spawning herring when entering the cold front in the Norwegian Sea
(ICES CM Documents;1996/H:13, Working paper, 1996)The distribution of Norwegian spring spawning herring when migrating to the feeding areas in the Norwegian Sea in spring has been mapped by surveys in April1995 and 1996. The schooling behaviour of the herring have been ... -
Food and feeding conditions of herring Clupea harengus in the Norwegian Sea
(ICES CM Documents;1996/L:20, Working paper, 1996)The feeding ecology of herring was studied using samples collected during cruises in 1994 and 1995. Investigations were carried out in the Møre shelf region off western Norway where the major spawning of herring occurs, ... -
Esterase variation in herring studied by isoelectric focusing
(ICES CM Documents;1997/AA:1, Working paper, 1997)Few suitable genetic characteristics for studying herring population structure are available, and the main aim of the study reported here has been to reveal traits which display useful genetic variations for application ... -
Occurence of blue whiting in trawl catches during surveys from Portugal to Faroe Islands, 1979- 1995
(ICES CM Documents;1996/S:30, Working paper, 1996)Historical data on blue whiting (Micromesistius poutassou) from survey trawl stations of 7 countries, have been congregated and prepared into special files, together with corresponding temperature and salinity observations. ... -

Acoustic abundance estimation of the stock of Norwegian spring spawning herring, winter 1995- 1996
(ICES CM Documents;1996/H:33, Working paper, 1996)Standard echo integration methodology has been applied to the stock of Norwegian spring spawning herring (Clupea harengus) wintering in the Ofotfjord-Tysfjord-Vestfjord system during late autumn 1995 and early winter ... -
Acoustic portrait of herring in Vestfjord, january 1996, with geostatistical analysis
(ICES CM Documents;1996/H:31, Working paper, 1996)In January 1996 the stock of Norwegian spring-spawning herring (Clupea harengus) was acoustically surveyed in the wintering area. Both immature and mature fish were present. Because of the comparative lateness of the ... -

Relations between seasonal migrations and fat content in Norwegian spring spawning herring (Clupea harengus L.)
(ICES CM Documents;1996/H:11, Working paper, 1996)The relationship between seasonal migrations and fat content in Norwegian spring spawning herring (whole herring and fillets) was examined using data for the period 1994-1996. During the feeding period (April-August) in ... -

Assessing growth of Northeast Arctic cod by a bioenergetics model
(ICES CM Documents;1996/G:16, Working paper, 1996)This paper represents an attempt to elucidate how fish body size differences and metabolic costs alter the relationship between growth and consumption using a bioenergetics model. The results show that the daily growth ... -
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 ... -
