Fisheries-induced life history changes in herring (Clupea harengus)
(ICES CM documents;2007/E:23, Working paper, 2007)Fishing changes not only the population abundance of the target species, but also its population dynamics and life-history traits. A number of studies have shown that life history traits related to the timing of maturation ... -
Food and feeding conditions of herring Clupea harengus in the Norwegian Sea
(ICES CM Documents;1996/L:20, Working paper, 1996)The feeding ecology of herring was studied using samples collected during cruises in 1994 and 1995. Investigations were carried out in the Møre shelf region off western Norway where the major spawning of herring occurs, ... -
Food and feeding of young herring larvae of Norwegian spring spawners
(ICES CM Documents;1976/H:36, Working paper, 1976)The gut contents of young herring larvae sampled each hour from 4 to 9 April 1967 around a floating drogue at three depth intervals were examined to study their feeding. Copepod eggs constituated more than 90% of the ... -
The food of herring larvae of Norwegian spring spawners

Further studies on stock size fluctuations and rate of exploitation of the Norwegian spring spawning herring, 1950 - 1971
(ICES CM Documents;1973/H:19, Working paper, 1973) -
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 in the Norwegian spring-spawning herring for the year-classes 1950 -1960 and 1973 -1983
(ICES CM Documents;1988/H:35, Working paper, 1988)Two periods with great differences in year-class abundance and recruitment where chosen for growth studies. In the first period the mean year-class strength at 3 years was 6 790 x 10[6] individuals while in the second ... -
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 patterns in otoliths as an indication of daily growth variations of larval herring (Clupea harengus) from an experimental ecosystem
(ICES CM Documents;1981/H:31, Working paper, 1981)Larval herring were released in a large outdoor basin four days after hatching and the mean growth in length and weight of the herring larvae and fry was monitored for 100 days. The food supply was estimated from weekly ... -
Harvest control rules and changing productivity: the working example of North Sea herring
(ICES CM documents, Working paper, 2006)North Sea herring is managed by the EU and Norway through a harvest control rule where target fishing mortalities are changed if the estimated SSB falls below a trigger biomass million tonnes). This management agreement ... -
Hermod, a single species model for the Norwegian spring spawning herring stock
(ICES CM Documents;1994/H:11, Working paper, 1994)HERMOD is a model for the population dynamics and migration of the Norwegian Spring spawning herring that is being developed with the double purpose of being an independent single species model and of being integrated ... -
