Sources of variations in weight and length of Atlantic salmon
(ICES CM Documents;1981/F:39, Working paper, 1981)Variance for weight and total length of four year classes of farmed Atlantic salmon after two years in the sea were distributed on strain, family, maturing/immature (after two winters) and sex. Highly significant variation ... -
Spatial and temporal patterns in recruitment of shrimp Pandalus borealis in the Barents Sea
(ICES CM documents, Working paper, 2000)The shrimp spawn in autumn and the eggs are carried as out roe by the females until spring when the larvae hatch. Within a period of 2-3 months the shrimp larvae settle to the bottom. Today’s assessment and forecast of ... -
Spatial patterns of age-0 cod survival in the Barents Sea
(ICES CM documents, Working paper, 2005)Apart from human harvest, recruitment dynamics is conceivably recognized as the main source of population variability of marine fish stocks. Factors affecting recruitment dynamics can change over both temporal and spatial ... -
Spawning and development of Calanus spp. in the Barents Sea
(ICES CM Documents;1994/L:22, Working paper, 1994)From 1986 to 1988 eight cruises were conducted in the Barents Sea, covering Atlantic water in central parts of the Sea and meltwater and Arctic water in the Polar front region. During the cruises hydrography, ... -
Spawning strategy and a mechanism for adaptive larval production in Arcto-Norwegian cod
(ICES CM Documents;1990/L:100, Working paper, 1990)The Arcto-Norwegian cod is spawning in the temperature stable Atlantic water, and the eggs ascend into the more temperature variable coastal water. Changes in time of peak spawning, up to 10 days within the last 60 ... -
