A three level pelagic trawl for near surface sampling of juvenile fish
(ICES CM Documents;1993/B:19, Working paper, 1993)In the northeast Atlantic Ocean catch rates of juvenile fish from pelagic trawls are used to calculate indices of relative abundance which are applied as a first indication of year class strength. A major constraint for ... -
Are reared juveniles fit for release into the wild?
(ICES CM Documents;1993/F:34, Working paper, 1993)The main question that has to be raised when planning to enhance natural fish populations is whether reared fish are fitted for a life in the wild, or more specifically, whether there are differences between reared and ... -
Bycatch of juvenile fish in the shrimp fishery - management based on bioeconomic criteria
(ICES CM Documents;1994/T:14, Working paper, 1994)The bycatch of juvenile fish can be a major problem in fisheries with small meshed trawls, such as fisheries for shrimp, (Pandalus borealis). A sorting grid that effectively removes most of the undersized fish has been ... -
Current patterns during pelagic stages determine interannual variability in length-at-age of juvenile Arcto-Norwegian cod
(ICES CM documents, Working paper, 2001) -
Effects of light on the development, activity and mortality of halibut (Hippoglossus hippoglossus L.) yolk sac larvae
(ICES CM Documents;1990/F:43, Working paper, 1990)Halibut yolk sac larvae were kept at different light intensities from Day 1 posthatch. Measurements of activity and swimming speed showed that larvae that were kept in darkness were more active, but had lower swimming ... -
Growth of scallop juveniles (Pecten maximus L.) in an enriched shallow seawater basin
(ICES CM Documents;1990/K:23, Working paper, 1990)The aim of this work was to see if a shallow, enriched seawater basin was a suitable location for scallop culture. Growth of great scallop juveniles (Pecten maximus L.) was compared with two open sea locations, and the ... -
How can a potential oil pollution affect the recruitment to fish stocks?
(ICES CM Documents;1989/Mini:5, Working paper, 1989)Eggs, larvae and the larvae's first search for food are the most critical stages in a fish life, both to threats from natural causes and pollution. Based on experimental studies of several species of fish eggs, larvae ... -
Large scale release experiment of juvenile lobsters, Homarus gammarus, in Norway
(ICES CM Documents;1990/K:2, Working paper, 1990)A large scale spring release of juvenile lobsters, Homarus gammarus, was conducted at Kvitsøy, southwestern Norway in March 1990. The lobsters, 14,700 one and a half year old and 8,700 six months old, were tagged internally ... -
Norwegian investigations in 1984 -1985 on juvenile herring
(ICES CM Documents;1985/H:53, Working paper, 1985)This paper describes tlte Norwegian investigations on juvenile herring (0-, I- and II-group) of the Norwegian spring spawning stock. The investigations were carried out in Norwegian coastal areas and in the Barents Sea ... -
Observer program for juvenile Northeast Arctic saithe
(Working paper, 2010-02)NEA saithe 0-group indices from observers along the coast does not seem to reflect the dynamics in year class strength very well and is therefore probably not suitable for improving future recruitment estimates for this stock. -
Prey selection of early juvenile cod (Gadus morhua L.) in the Barents Sea
(ICES CM documents, Conference object, 2006) -
The relation between fishing mortality on juveniles and total yield of Arcto-Norwegian cod

Report of the International Young Fish Survey in the North Sea, Skagerrak and Kattegat in 1990
(ICES CM Documents;1990/H:13, Working paper, 1990)Introduction: The results from the International Young Fish survey become available in successive steps. During the survey the numbers of 1-group fish, based on fish below a certain length, are exchanged between the ... -

Size of spawning Arcto-Norwegian cod (Gadus morhua L.) and the effects on their eggs and early larvae
(ICES CM Documents;1993/G:41, Working paper, 1993)Using a new method for determining the stage of spawning in batch spawners, a positive correlation between the length of Arcto-Norwegian cod females, having spawned 25-75% of their eggs, and the egg diameter was established. ... -
Size selective mortality in Norwegian spring spawning herring juveniles?
(ICES CM documents, Working paper, 2005)The growth-mortality hypothesis, where survival during the larval stage is positively related to size, is tested for Norwegian spring spawning herring (Clupea harengus L.). The daily increment width in the otoliths is ...
