Spawner quality effects on two measures of reproductive potential: have we been counting our eggs before they've hatched?
(ICES CM documents, Working paper, 1999)Recent studies have found positive associations between recruitment and indices of spawner quality (condition) for stocks exhibiting an indeterminate relationship between recruitment and spawner biomass. This suggests ... -
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 and stock size of North Sea mackerel in 1981

Spawning and trends in spawning stock size of the North Sea mackerel during the period 1973-1980
(ICES CM Documents;1981/H:16, Working paper, 1981)A declinining trend in the size of the spawning stock of North Sea mackerel is described by data obtained from egg surveys. During the period 1973-1980 the spawning stock size was reduced by 60-70%. A similar stock development ... -

Spawning of Norwegian spring spawning herring (Clupea harengus L.) related to geographical location and population structure
(ICES CM Documents;1997/CC:17, Working paper, 1997)The catch, distribution, and biology were studied in Norwegian spring spawning herring during the spawning season in 1995. Both the spawning time and choice of spawning grounds were influenced by the size and condition ... -

The spawning period for mackerel in the North Sea
(ICES CM Documents;1977/H:26, Working paper, 1977)The intensity and duration of the spawning of mackerel (Scomber scombrus L.) was studied by daily plankton sampling from late May to early July 1976 at a single locality in the central part of the spawning area in the North ... -
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 ... -

Spheres for calibrating an eleven-frequency acoustic measurement system
(ICES CM Documents;1989/B:3, Working paper, 1989)Calibration of a single resonant transducer by standard sphere is a simple matter. How does one calibrate an array composed of eleven different resonant transducers spanning the frequency range from 27 to 710 kHz? A ... -
