Growth and maturity of sprat in Norwegian coastal waters
(ICES CM documents, Working paper, 1998)Data on length, age and maturity were analysed to study the growth and spawning of sprat in fjords on the Norwegian West Coast. The data were sampled in 4 fjord Areas in November 1993-1997 (for mean length and weight-at-age) ... -
Growth and seawater adaptation in Atlantic salmon (Salmo salar) raised at different experimental photoperiods
(ICES CM Documents;1976/E:39, Working paper, 1976)A study was made of the effect of day length and feeding-time on the smolting process and on growth of Atlantic salmon during smolting. The experiment consisted of five experimental groups with different day lengths. Highest ... -
Growth and survival studies of halibut (Hippoglossus hippoglossus L.) from hatching to beyond metamorphosis carried out in mesocosms
(ICES CM Documents;1986/F:16, Working paper, 1986)To each of five floating plastic bags 1500 halibut larvae were transferred from the hatchery one day after hatching. The plastic bags had a volume of 11.5 m3, a total depth of 5.5 m and they were moored to floating ... -
Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas
(ICES CM documents, Working paper, 2005)Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas The hatched larvae of Norwegian spring spawning herring are transported to ... -
Growth in the Norwegian spring-spawning herring for the year-classes 1950 -1960 and 1973 -1983
(ICES CM Documents;1988/H:35, Working paper, 1988)Two periods with great differences in year-class abundance and recruitment where chosen for growth studies. In the first period the mean year-class strength at 3 years was 6 790 x 10[6] individuals while in the second ... -
Growth of 0-group fish in relation to temperature conditions in the Barents Sea during the period 1965- 1989
(ICES CM Documents;1990/G:49, Working paper, 1990)Since 1965 the International 0-group fish survey has been carried out in the Barents Sea during late August and early September. The main purpose is to determine the year-class strength of some commercial fish species ... -
Growth of Atlantic herring larvae (Clupea harengus L.) in response to climatic long term trends (NAO) and to hydrographical features in the northern North Sea in the period 1990- 1997
(ICES CM Documents;1999/L:26, Working paper, 1999)Herring larvae were sampled during the IHLS in the ICES area IVa from 1990 to 1997. Larval growth was determined based on otolith microstructure analysis from larvae of 7-25mm standard length. The data were correlated ... -
Growth of capelin in relation to zooplankton biomass in the Barents Sea
(ICES CM Documents;1995/P:5, Working paper, 1995)Growth of capelin in the Barents Sea stock has been found to vary considerably both between years and between different parts of the distribution area. The aim of this paper is to compare such growth variations with ... -
Growth of juvenile halibut (Hippoglossus hippoglossus L.) in captivity
(ICES CM Documents;1986/F:20, Working paper, 1986)The growth and substrate preference of collected wild juvenile halibut under culture conditions were investigated. The size of the collected fish conformed well with year class data from earlier studies. Halibut growth ... -
Growth of northeast arctic cod in relation to ambient temperature
(ICES CM documents, Working paper, 1996)In the present study temperature related changes in horizontal distribution are described and the influence of temperature on the growth of Northeast Arctic cod is interpreted. Data from acoustic-and bottom trawl surveys ... -
Growth of Polar cod (Boreogadus saida) in the Barents Sea
(ICES CM Documents;1990/G:47, Working paper, 1990)Observed length-at-age, and backcalculated lengths based on otolith measurements, from samples of polar cod collected in the Barents Sea in autumn of 1987 to 1989, were analysed. An increase in individual length growth ... -
Growth of scallop juveniles (Pecten maximus L.) in an enriched shallow seawater basin
(ICES CM Documents;1990/K:23, Working paper, 1990)The aim of this work was to see if a shallow, enriched seawater basin was a suitable location for scallop culture. Growth of great scallop juveniles (Pecten maximus L.) was compared with two open sea locations, and the ... -
Growth of the Barents Sea capelin (Mallotus villosus) in relation to climate
(ICES CM Documents;1986/H:64, Working paper, 1986)The history of capelin assessment in the Barents Sea has shown that the growth of individual capelin has varied between years and different parts of the capelin distribution area. As the number of individuals in this ... -
Growth of the Barents Sea capelin compared to stock size and geographical distribution
(ICES CM Documents;1986/H:38, Working paper, 1986)The growth of individual capelin in the Barents Sea stock was analysed in relation to the geographical distribution and size of the stock in the feeding season, and the density of fish in the feeding area. The growth ... -
