Age distributions for spawning capelin 1954 -1984: A review of some selected literature
(ICES CM Documents;1985/H:36, Working paper, 1985)This paper gives a brief review of published information about the age distributions of maturing and spawning capelin in the years 1954-84. The results are presented in a table and a figure, and discussed. -
Aluminium accumulation on eggs and hatching system during the incubation period - an important cause of variable hatching success ?
(ICES CM Documents;1984/F:27, Working paper, 1984)Groups of rainbow trout eggs were incubated in duplicate in trays with PVC screens and original aluminium screens. During incubation aluminium bound to sediments was deposited on eggs and hatching systems. By adding ... -
Appetite feeding experiments with cod - preliminary results
(ICES CM Documents;1980/F:20, Working paper, 1980)Various size groups of cod were kept in periods of 3 to 4 weeks in ad lib. feeding experiments at deprivation times from 4 to 48 hours. Ration size varied from 0.4 to 6.2 % (wet weight) per meal in the series. Average ... -
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 ... -
Artificial hatching substrate and different time of transfer to startfeeding: Effect on growth and protease activities of the Atlantic salmon (Salmo salar).
(ICES CM Documents;1984/F:22, Working paper, 1984)Groups of Atlantic salmon (Salmo salar) eggs were hatched in a Californian hatching system with and without an astro-turf artificial substrate, and food was presented at four different points in development. Dry weight ... -
Artificial hatching substrate in the mass rearing of larval Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:30, Working paper, 1984)Eggs from individual Atlantic salmon (Salmo salar) were hatched in a Californian hatching system with and without an astro-turf artificial substrate and growth during the first 200 days following hatching was ... -
Artificial hatching substrate, effect on RNA / DNA ratio and protein retention during the yolk-sac period of Atlantic salmon (Salmo salar)
(ICES CM Documents;1985/F:31, Working paper, 1985)Genetical groups of Atlantic salmon (Salmo salar) were hatched in a Caiifonian hatching system with and without an astro-turf artificial hatching substrate, and were later transfered to separate feeding units. The ... -
Assessing growth of Northeast Arctic cod by a bioenergetics model
(ICES CM Documents;1996/G:16, Working paper, 1996)This paper represents an attempt to elucidate how fish body size differences and metabolic costs alter the relationship between growth and consumption using a bioenergetics model. The results show that the daily growth ... -
Atlanto-scandian herring and capelin working group report [Copenhagen, 4 -6 May, 1982]
(ICES CM Documents;1982/Assess:12, Working paper, 1982) -
Avoidance from petroleum hydrocarbons by the cod (Gadus morhua)

Back-calculated length at age in Norwegian spring-spawning herring (Clupea harengus L.) : Estimating the common intercept or origin by tuning back-calculated length frequencies to observed ones
(ICES CM Documents;1996/D:9, Working paper, 1996)In Norwegian spring-spawning herring the common intercept of the back-calculating formula, as estimated by linear regression of the fish-scale relationship, grosssly overestimated the back-calculated length frequencie ... -
Bacterial diseases of eggs and yolk sac larvae of halibut (Hippoglossus hippoglossus L.): Characterization and experimental infection
(ICES CM Documents;1990/F:38, Working paper, 1990)Scanning electron micrographs of halibut eggs which were shown to have an epiflora dominated by a Flexibacter sp., revealed wounds colonized by large amounts of bacteria. The chorion was penetrated in most wounds, and ... -

Biological and economic implications of a multi-gear fishery for greenland halibut (Reinhardtius hippoglossoides)
(ICES CM Documents;1995/S:5, Working paper, 1995)This paper focuses on the level and distribution of fishing mortality in a multigear fishery, and its effect on biological and economic parameters. The Greenland halibut stock in ICES Sub-areas I and Il is at a historically ... -
Biological reference points for north-east Arctic cod and haddock
(ICES CM Documents;1989/G:29, Working paper, 1989)It has been suggested by ACFM that Fmed might be preferable to Fmax as a biological reference point for the North-East Arctic cod. However, the Fmed level of more than twice Fmax appeared high, and it was known to have ... -
Blue whiting in the Norwegian Sea, spring and summer 1995 and 1996
(ICES CM Documents;1997/CC:15, Working paper, 1997)The Norwegian Sea is an important feeding area for blue whiting in the Northeast Atlantic. The adult blue whiting migrates into the Norwegian Sea after spawning along the continental slope west of The British Isles. A ... -
Can a bioenergetics model explain growth of the northeast Arctic cod?
(ICES CM Documents;1994/G:7, Working paper, 1994)For the period 1984 to 1991, the individual maximum daily consumption in calories (cmax) based on 33000 cod stomach samples is given by the power equation: Cmax = 68.84 · W ^0,934 where W represents the total fish ... -
