Gastric evacuation rate in mackerel (Scomber scombrus L.)
(ICES CM documents, Working paper, 1983)About 1500 mackerel, 25-45 cm in Length, were kept in a net for l0 days. In two experiments the fish were £ed frozen euphausiids -ad. libiturn, and the wet weight of the stomach content determined every second hour for ... -
Gelatinous zooplankton on the Mid-Atlantic Ridge, Distribution patterns of trawl-collected planktonic cnidarians
(ICES CM documents;2008/C:21, Working paper, 2008)The Mid-Atlantic Ridge (MAR) between 40˚N (Azores) and 63˚N (Iceland) is the largest topographic feature in the North Atlantic Ocean. However, the fauna and ecological significance of mid-ocean ridges has remained poorly ... -
A general system for logging information from instruments in the sea.
(ICES CM Documents;1978/B:23, Working paper, 1978)The paper describes a logging system which aims at integrating various forrns for primary data recording into a common standard that can be handled by the same reading and data processing equipment, Some illustrative ... -

(ICES CM documents;2009/Q:14, Working paper, 2009) -
Genetic comparison of salmon (Salmo salar L.) from the White Sea and the Atlantic ocean
(ICES CM Documents;1996/M:13, Working paper, 1996)Samples of salmon (Salmo salar) from River Kachkovka and R. Nilma in northem Russia were analysed by starch gel electrophoresis and compared to three Norwegian stocks, R. Neiden in northern Norway and R. Øyre and R. Hop ... -

Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -
Genomic signatures of local adaptation in natural populations of Atlantic cod: implications for interactions between aquaculture and wild cod populations

Geographic information systems (GIS) as tools for better integrated coastal zone planning and management (ICZP/M)
(ICES CM Documents;2000/O:3, Working paper, 2000)Geographic information systems (GIS) has practical applications in many areas, one of them being integrated coastal zone planning and management (ICZP/M). GIS can help combine several types of data from different sectors ... -
Geostatistical analysis of acoustic survey data on 0-group herring in a fjord
(ICES CM Documents;1992/D:10, Working paper, 1992)An essentially pure aggregation of 0-group herring in Altafjord in northern Norway was acoustically surveyed on each of the first three days of December 1991. Measurements were made at 38 kHz during each survey and at ... -
Getting fat in a hurry: food consumption during the feeding migration of NSS herring
(ICES CM Documents;2004/K:64, Working paper, 2004)The Norwegian spring-spawning (NSS) herring Clupea harengus inhabits a seasonal environment where food is abundant only during a short period of the year. During that period NSS herring store energy for metabolic ... -
Green water in larviculture - An experiment with natural phytoplankton in tanks for first feeding of halibut larvae (Hippoglossus hippoglossus L.)
(ICES CM Documents;1990/F:61, Working paper, 1990)At 232 day degrees, halibut larvae were transferred from indoor tanks to 1.7 m^3 outdoor tanks for first feeding. The number in each tank was approximately 750. Three tanks were continuously given algal suspension ("green ... -
Grid devices to select shrimp size in trawls
(ICES CM Documents;1993/B:35, Working paper, 1993)Discard of small shrimps and fish is a substantial problem in the fishery for deepwater shrimp in the Northwest Atlantic. In order to solve this problem, different grid devices are under development to sort out discard ... -
Grid-sorting of penned saithe
(ICES CM Documents;1992/B:11, Working paper, 1992)Size selection of penned saithe was obtained by forcing the fish against an adjustable grid mounted in the end of net pens. The size selection was rather sharp, with a selection range of about 5 cm only. All fish forced ... -

Growth and maturity of sprat in Norwegian coastal waters
(ICES CM documents, Working paper, 1998)Data on length, age and maturity were analysed to study the growth and spawning of sprat in fjords on the Norwegian West Coast. The data were sampled in 4 fjord Areas in November 1993-1997 (for mean length and weight-at-age) ... -
Growth and seawater adaptation in Atlantic salmon (Salmo salar) raised at different experimental photoperiods
(ICES CM Documents;1976/E:39, Working paper, 1976)A study was made of the effect of day length and feeding-time on the smolting process and on growth of Atlantic salmon during smolting. The experiment consisted of five experimental groups with different day lengths. Highest ... -
