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 ... -
Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas
(ICES CM documents, Working paper, 2005)Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas The hatched larvae of Norwegian spring spawning herring are transported to ... -
Growth of 0-group fish in relation to temperature conditions in the Barents Sea during the period 1965- 1989
(ICES CM Documents;1990/G:49, Working paper, 1990)Since 1965 the International 0-group fish survey has been carried out in the Barents Sea during late August and early September. The main purpose is to determine the year-class strength of some commercial fish species ... -
Growth of Atlantic herring larvae (Clupea harengus L.) in response to climatic long term trends (NAO) and to hydrographical features in the northern North Sea in the period 1990- 1997
(ICES CM Documents;1999/L:26, Working paper, 1999)Herring larvae were sampled during the IHLS in the ICES area IVa from 1990 to 1997. Larval growth was determined based on otolith microstructure analysis from larvae of 7-25mm standard length. The data were correlated ... -
Growth of capelin in relation to zooplankton biomass in the Barents Sea
(ICES CM Documents;1995/P:5, Working paper, 1995)Growth of capelin in the Barents Sea stock has been found to vary considerably both between years and between different parts of the distribution area. The aim of this paper is to compare such growth variations with ... -
