Artificial hatching substrate and different time of transfer to startfeeding: Effect on growth and protease activities of the Atlantic salmon (Salmo salar).
(ICES CM Documents;1984/F:22, Working paper, 1984)Groups of Atlantic salmon (Salmo salar) eggs were hatched in a Californian hatching system with and without an astro-turf artificial substrate, and food was presented at four different points in development. Dry weight ... -
Artificial hatching substrate in the mass rearing of larval Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:30, Working paper, 1984)Eggs from individual Atlantic salmon (Salmo salar) were hatched in a Californian hatching system with and without an astro-turf artificial substrate and growth during the first 200 days following hatching was ... -
Artificial hatching substrate, effect on RNA / DNA ratio and protein retention during the yolk-sac period of Atlantic salmon (Salmo salar)
(ICES CM Documents;1985/F:31, Working paper, 1985)Genetical groups of Atlantic salmon (Salmo salar) were hatched in a Caiifonian hatching system with and without an astro-turf artificial hatching substrate, and were later transfered to separate feeding units. The ... -
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 ... -
Assessing natural mortality of anchovy from surveys' population and biomass estimates
(ICES CM documents;2010/C:12, Working paper, 2010)In ordinary catch at age models, natural mortality conditions and determines the catchabilities at age obtained for the surveys which tune the assessments. For the same reason, inferring the Natural mortality of a fish ... -
Assessing the effect of intra-haul correlation and variable density on population estimates from marine surveys
(ICES CM Documents;1991/D:14, Working paper, 1991)In a previous paper (Pennington and Vølstad, Biometrics 47, 1991) it was suggested that reducing the size of the sampling unit generally used in marine surveys could increase the precision of abundance estimates. But if ... -
Assessing the impact of effluents from offshore activities by their biological effects –local and regional scales

Assessing the precision of the estimated age distribution of the commercial catch of Northeast Arctic cod
(ICES CM documents, Working paper, 2001)The assessment of Northeast Arctic cod is based on estimates of the commercial catch numbers at age. The age structure of the catch is estimated by sampling individuals from commercial fishing trips. Though it is commonly ... -
Assessing trawl-survey estimates of frequency distributions
(ICES CM Documents;2000/K:23, Working paper, 2000)Marine trawl surveys catch a cluster of fish at each station and fish caught together tend to have more similar characteristics, such as length, age, stomach contents etc., than those in the entire population. When this ... -
Assessment and management of Barents Sea capelin
(PINRO-IMR Symposium, Conference object, 1985)The history of the Barents Sea capelin fishery and fishery regulations is reviewed. Basic assessment data and theories are described and discussed in the light of the population dynamics governing the sustainable yield. -
Assessment of potential oil pollution damages on fish resources. Some examples from the area outside mid-Norway
(ICES CM Documents;1987/E:13, Working paper, 1987)Detailed mapping of fish eggs and larvae both in space and time is essential knowledge when realistic assessments of oil pollution damages to the fish resources are established. The text explain with some examples our ... -
Assessment of the North-East Arctic and North Sea Stocks of Saithe Taking Into Account Migration
(ICES CM Documents;1981/G:36, Working paper, 1981)Tagging experiments have shown that there is a substantial migration of young saithe from the Norwegian coast north of 62°N to the North Sea. Assessments of the North-East Arctic and North Sea Stocks of saithe were made ... -
Assessments for management of living marine resources in the Barents Sea and adjacent waters – a focus on methodology
(IMR/PINRO Joint Report Series;3/2014, Research report, 2015) -
Assessments of the Arcto-Norwegian cod stock : The yield and size of the mature stock versus fishing pattern, fishing effort, natural mortality and mesh size
(ICES CM Documents;1975/F:34, Working paper, 1975) -
Assigning values of target strength and equivalent beam angle in acoustic surveys of fish
(ICES CM Documents;1991/B:34, Working paper, 1991)Contrary to popular opinion, the equivalent beam angle (~) is not determined solely by the transducer directivity. Rather, like the target strength TS, it also depends on the scattering properties of the target fish, but ... -
The atlantic inflow to the North Sea and the Skagerrak indicated by surface observations
(ICES CM Documents;1978/C:17, Working paper, 1978)By means of surface observations of temperature and salinity along shipping routes across the North Sea it is shown that the Atlantic inflow along the western and southern edge of the Norwegian Channel seems to reach ... -
