Size and age composition of the Norwegian purse-seine catches in the North Sea and the Skagerak
(ICES CM Documents;1968/H:21, Working paper, 1968) -
Size and condition of mackerel in research vessel trawl hauls versus commercial purse seine catches: implications for acoustic biomass estimation
(ICES CM documents, Working paper, 2006)In September, after the summer feeding has ceased, the Northeast Atlantic mackerel (Scomber scombrus) stock tends to aggregate in ICES Area IVa before they start to migrate southwards in December-February towards the ... -
Size and exploitation of the mackerel stock in the Skagerrak and North-Eastern North Sea
(ICES CM Documents;1970/H:26, Working paper, 1970) -
Size dependency in the migrations and distribution of Norwegian spring spawning herring
(ICES CM documents, Working paper, 2003)The size at first spawning is comparatively larger in Norwegian spring spawning herring (Clupea harengus L.) than in other herring stocks in the Atlantic and Pacific oceans. This is probably an adaptation to a life with ... -
Size distribution of the edible crab (Cancer pagurus) and catch/effort in the crab fishery at one locality in Norway during 1972-1974
(ICES CM Documents;1975/K:53, Working paper, 1975) -
Size of eggs and nauplii of calanoid copepods in the Barents Sea; influence of environmental and maternal factors
(ICES CM Documents;1991/L:63, Working paper, 1991)During the years 1986 to 1988 eight cruises were conducted in the central and western parts of the Barents Sea. The cruises, together spanning the time period from January to July, covered most developmental stages of ... -
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 effects of a plastic body on longline hooks
(ICES CM Documents;1991/B:46, Working paper, 1991)The potential for improving size selectivity of longlines by using a plastic body attached to the hook shank was tested in a fishing trial for tusk (Brosme brosme), ling (Molva molva) and haddock (Melanogrammus aeglefinus). ... -
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 ... -
Size structure, age-size dynamics and life history variation
(ICES CM documents;2008/F:13, Working paper, 2008)Here we present a new technique to study life history variation when only length distributions of populations are known. Shape of length distribution in a population is to a significant extent determined by the degree ... -
Size-selection of mackerel and saithe in purse seine
(ICES CM Documents;1994/B:28, Working paper, 1994)In purse seine fisheries, there may exist potentials for size selection because some of the fish in the catch are less than the legal size, and because different size groups are paid differently. Both potentials are ... -
SKAGEX 1990. Preliminary results from the nutrient intercalibration
(ICES CM Documents;1990/C:44, Working paper, 1990)An important part of SKAGEX 1990 was the nutrient intercalibration, which was performed to simulate ordinary work at sea. 44 water samples of 0,5 liter were delivered to each of the 13 participating research vessels in ... -
SKAGEX: Some preliminary results
(ICES CM Documents;1991/C:2, Working paper, 1991)A series of synoptic hydrographic and biological investigations were carried out in the Skagerrak area in May-June and September 1990 and in January and May 1991 (Skagerrak Experiment or SKAGEX). -
Small scale multi-species functional response of northeast Atlantic minke whales
(ICES CM documents, Working paper, 2005) -
Smoltification of Atlantic salmon in different water qualities and subsequent growth in sea water, following distinct transfer strategies from freshwater
(ICES CM Documents;1990/F:64, Working paper, 1990)Atlantic salmon parr were kept in four different fresh water qualities for seven months before smoltification, which was characterized by plasma chloride content after sea water challenge tests. Three groups were transferred ... -
Snake pipefish (Entelurus aequoreus) intrusion as a new species into the Barents Sea ecosystem.
(ICES CM documents;2007/H:04, Working paper, 2007)The snake pipefish Entelurus aequoreus is a member of the Syngnathidae family. The open water species is distributed in the eastern Atlantic, from the Azores to Iceland and Norway, including the Baltic Sea. Concentrations ... -
Some aspects of fishing patterns in relation to fishery management
(ICES CM Documents;1975/H:52, Working paper, 1975) -
Some aspects of the interrelation between the herring in the Norwegian Sea and the stocks of capelin and cod in the Barents Sea
(ICES CM Documents;1988/H:42, Working paper, 1988)The paper reviews the life history and exploitation of the Norwegian spring spawning herring, the Barents Sea capelin and the north-east Arctic cod. On this basis and from relevent knowledge of climatic conditions, the ... -
Some biological factors of blue whiting in the north-east Atlantic
(ICES CM Documents;1990/H:15, Working paper, 1990)Total mortality coefficients of blue whiting in the spawning area as well as in the feeding area, were obtained for various years and for various yearclasses, by calculating the regressions of the natural logarithms of ... -
Some comments to the problem of adjusting TACs to mesh size changes.
(ICES CM Documents;1979/G:56, Working paper, 1979)Mesh assessments are usually carried out by calculating "short term losses" and "long term gains" expected from a change in the minimum legal mesh size, assuming no change in total fishing effort or its distribution by ...
