(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)1. Catch and escapement of Kvichak River sockeye salmon (Oncorhynchus nerka) and smolt production from Iliamna Lake, the nursery area, have been determined annually since 1955. Since 1962, information has been collected ... -
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 ... -
Growth of the Barents Sea capelin of the year-classes 1967-70
(ICES CM Documents;1977/H:39, Working paper, 1977)Otoliths of the 1967-70 year-classes of the Barents Sea capelin have been analyzed. For otoliths with radius < 0,74 mm there was a close, linear relation between fish length and otolith radia. For larger otoliths the ... -
Growth of the Barents Sea capelin of the yearclasses 1975-1981
(PINRO-IMR Symposium, Conference object, 1985)The method of backcalculating fish lengths based on yearly growth markings in the otoliths is applied to estimate growth of capelin in the yearclasses 1975 to 1981. The Barents Sea is divided into five subareas, and the ... -
Growth of wild and domesticated Atlantic cod Gadus morhua reared under semi-commercial conditions
(Journal article; Peer reviewed, 2018)Genetic interactions between farmed escapees and wild fish represent a challenge to environmentally sustainable aquaculture. Breeding programs for Atlantic cod Gadus morhua have been initiated; however, the genetic response ... -
Growth patterns in otoliths as an indication of daily growth variations of larval herring (Clupea harengus) from an experimental ecosystem
(ICES CM Documents;1981/H:31, Working paper, 1981)Larval herring were released in a large outdoor basin four days after hatching and the mean growth in length and weight of the herring larvae and fry was monitored for 100 days. The food supply was estimated from weekly ... -
Growth patterns in the North Sea and western mackerel in Norwegian catches 1960- 85
(ICES CM Documents;1989/H:21, Working paper, 1989)Length, weight and age in random samples from Norwegian catches of' mackerel from 1960 to 1985 have been reviewed. A standard growth curve was constructed by applying a modified von Bertalanffy equation to all data. The ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
(Peer reviewed; Journal article, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
Growth portfolios buffer climate-linked environmental change in marine systems
(Peer reviewed; Journal article, 2022)Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ... -

Growth rate and age at sexual maturity of Atlantic salmon smoltifying aged one and two years
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1979)Post-smolt growth rate and age at first maturation are compared for sib groups or population groups of salmon originating from Norwegian rivers and fish farms. Generally, high correlations were found between corresponding ... -
Growth rate and age at sexual maturity of Atlantic salmon smoltifying at one and two years of age
(ICES CM Documents;1978/F:23, Working paper, 1978)Postsmolt growth rate and age at first maturation are compared for sibgroup or population groups of salmon originating from Norwegian rivers and fish farms. Generally high correlations were found between corresponding ... -
Growth rates and age distributions of capelin (Mallotus villosus) larvae in the Barents Sea investigated by otolith increment analysis
(ICES CM documents, Working paper, 2004)In order to investigate age distributions and growth rates, otoliths from capelin larvae collected from the Barents Sea during the summers 2001-2003 were analysed using otolith microstructure analysis. Stations were ... -
Growth rates in cultured common wolffish (Anarhicahas lupus) and spotted wolffish (A. minor)
(ICES CM Documents;1990/F:2, Working paper, 1990)Field caught common wolffish (Anarhichas lupus) and spotted wolffish (A. minor) have been raised from fry on dry pellets. The two species have experienced annual fluctuations in temperature between 6 and 12 °C and the ... -
Growth reaction norms of domesticated, wild and hybrid Atlantic salmon families in response to differing social and physical environments
(Journal article; Peer reviewed, 2013-10-28)Background: Directional selection for growth has resulted in the 9-10th generation of domesticated Atlantic salmon Salmo salar L. outgrowing wild salmon by a ratio of approximately 3: 1 when reared under standard hatchery ... -
