In vitro ecotoxicological assessment of pelagic ecosystems
(ICES CM documents, Working paper, 2002)The ICES biological effects monitoring in pelagic ecosystems (BECPELAG) workshop is a multi-national, multi-disciplinary workshop aimed at establishing suitable techniques for monitoring the effects of contaminants on ... -
In/out-flow of coastal water in Vestfjorden
(ICES CM Documents;1978/C:51, Working paper, 1978)Hydrographic sections in Vestfjorden, Northern Norway, during winter 1977 showed strong horizontal temperature gradients on the west side of the fjord indicating an outflow of cold coastal water. Analysis of sea thermograph ... -
Including climate into the assessment of future fish recruitment, using multiple regression models.
(ICES CM documents, Working paper, 2005)Climate variability has generally not been included in the assessment of fish stocks in the Barents Sea and Norwegian Sea. However, in recent years there has been a focus on implementing climate variability in the assessment ... -
Incorporating experimentally derived estimates of survey trawl catchability into the stock assessment process
(ICES CM Documents;1997/W:5, Working paper, 1997)During the course of the April, 1996, meeting of the Fishing Technology and Fish Behavior Working Group it became clear to many that the methodology for experimentally estimating the catchability of survey trawls might ... -
Increased growth rate in Atlantic salmon parr by using a two-colour diet
(ICES CM Documents;1985/F:17, Working paper, 1985)Fishes hunting by sight are known to pay a cost of confusion when faced with high densities of uniform food particles. In such instances, awareness of other stimuli reduces feeding efficiency such that the fishes prefer ... -
Incubation of halibut yolk sac larvae improved by addition of freshwater and oxygen
(ICES CM Documents;1998/L:14, Working paper, 1998)Halibut fry has been produced regularly by scientific and commercial institutions since late 80- ties. The yearly number of halibut fry produced have, however, not fulfllled the optimistic expectations. This could partly ... -
Indication of high natural mortality for juvenile herring from acoustic and tagging data.
(ICES CM Documents;1980/H:62, Working paper, 1980)Natural mortality for juvenile herring (Norwegian Spring spawners) is discussed on the basis of following data: 1. Acoustic estimates of the 1975 and 1976 yearclasses of herring as 0-group and estimates from tagging ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
Individual growth rate and age at first sexual maturity in atlantic salmon
(ICES CM Documents;1977/E:60, Working paper, 1977) -
Individual growth rate and age at sexual maturity in rainbow trout
(ICES CM Documents;1978/F:22, Working paper, 1978)Growth rate and possible connection between growth rate and age at sexual maturity were studied on individually tagged rainbow trout from different sib groups. Great variation in growth rate and age at first sexual ... -
Induced deformities on larvae of the Atlantic halibut (Hippoglossus hippoglossus L.). A new experimental approach.
(ICES CM Documents;1990/F:45, Working paper, 1990)Introduction: The atlantic halibut is viewed as a promising species for cold water aquaculture, and have been subjected to extensive research efforts both in Norway and in U.K. the later years. As the biology, and ... -

Infection success of salmon lice related to temperature and implications for regional size of salmon production areas
(ICES CM Documents;2002/T:1, Working paper, 2002)The development rate for salmon lice larvae is highly temperature-dependent. Hence, the time from hatching of nauplii to an infectious copepodid will vary with the natural cycles in the sea. The salmon lice life span is ... -
The influence of byproducts from vinylchloride production on fertilization, development and larval survival on plaice, cod and herring eggs
(ICES CM Documents;1971/E:9, Working paper, 1971) -
Influence of climate on recruitment and migration of fish stocks in the North Sea
(ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
The influence of fish behaviour on acoustic abundance estimates during the spawning season in Norwegian spring-spawning herring
(ICES CM documents, Working paper, 2001) -
The influence of light and food density on the feeding success in larvae of cod (Gadus morhua L.); field and laboratory observations
(ICES CM Documents;1976/F:34, Working paper, 1976) -
Influence of sea temperature on herring distribution and migration in the Norwegian Sea in April 1997
(ICES CM Documents;1999/M:3, Working paper, 1999)After spawning at the west coast of Norway, the Norwegian spring spawning herring migrates northwestwards into the Norwegian Sea to feed in early April. The herring enters areas with distinct oceanographic features both ... -
