An attempt to start feed cod larvae with artificial diets
(ICES CM Documents;1981/F:14, Working paper, 1981)Larval cod were fed 8 different diets based on zooplancton and hen's eggs. All but one diets were ingested, but no growth was observed. The failure of the diets to promote growth is thouqht to be related to the low digestive ... -
Changes in buoyancy and activity during starvation of cod larvae (Gadus morhua L. )
(ICES CM Documents;1976/F:33, Working paper, 1976) -
A comparison of egg quality and larval viability between cultured coastal cod and wild arcto-norwegian cod
(ICES CM documents;1991/F:41;, Working paper, 1991)Experiments on cod eggs revealed an inverse relationship between egg diameter and mortality. Further, larvae hatching from small eggs showed a redeuced feeding ability. Other methods to characterice larval viability ... -
Endocrine and nutritional factors affecting the first food uptake by cod larvae
(ICES CM Documents;1982/F:17, Working paper, 1982) -
Feeding conditions of north-east Arctic (Arcto-Norwegian) cod larvae compared to the Rothschild-Osborn theory on small-scale turbulence and plankton contact rates
(ICES CM Documents;1989/G:19, Working paper, 1989)Data on first feeding North-east arctic cod larvae in Lofoten, sampled during the period 1976 - 1984, are examined to verify the theory on the influence of microturbulence on the contact rate between predator and prey ... -
The influence of light and food density on the feeding success in larvae of cod (Gadus morhua L.); field and laboratory observations
(ICES CM Documents;1976/F:34, Working paper, 1976) -
Intensive production of cod fry at Austevoll. Final report.
(ICES CM Documents;1984/F:33, Working paper, 1984)The experiences of this final season of the intensive cod fry production experiment are summed up. The brood stock yielded 369 liters of cod eggs. The production experiment in plastic pens had very high survival, but ... -
Large-scale rearing of cod fry (Gadus morhua) in an inlet
(ICES CM Documents;1981/F:11, Working paper, 1981) -
Mass-production of cod fry (Gadus morhua L.) in a large basin in western Norway - a new approach
(ICES CM Documents;1984/F:16, Working paper, 1984)In February 1984, the fresh water in a small lake was replaced by seawater pumped from 40 m depth. Four-day old cod larvae were transferred on 11 and 26 April into this seawater basin, which was 5 m above sea level with ... -
Mass-production of cod fry in a pond in western Norway, with additional feeding post-metamorphosis
(ICES CM Documents;1983/F:5, Working paper, 1983) -
Modelling rule-based behaviour: habitat selection and the growth–survival trade-off in larval cod
(ICES CM documents;2009/T:03, Working paper, 2009) -
Preliminary report of investigations of cod-eggs and larvae in the Lofoten area in the years 1968-1972
(ICES CM Documents;1974/F:37, Working paper, 1974) -
Present ssatus of an intensive cod larvae rearing experiment at Austevoll
(ICES CM Documents;1981/F:13, Working paper, 1981)Cod yolk sac larvae were attempted start fed on natural plankton in plastic pens. The majority of the larval groups were also hatched in these pens. None of the sampled larvae had ingested feed, and all groups died out ... -
Present status of an intensive cod-rearing experiment at Austevoll, Norway
(ICES CM Documents;1982/F:16, Working paper, 1982) -
Primary growth increments in otoliths of cod larvae (Gadus morhua L.) of the Arcto-Norwegian cod stock
(ICES CM Documents;1981/G:54, Working paper, 1981)Primary growth increments are laid down in the otoliths of cod larvae living in a habitat where the light intensity is above the light threshold for visual feeding during 24 hours, and in which the larvae were observed to ... -
Sublethal effects of the water-soluble fraction of Ekofisk crude oil on the early larval stages of cod (Gadus morhua L.)
(ICES CM Documents;1981/E:52, Working paper, 1981) -
Vertical distribution and feeding of cod larvae in relation to occurrence and size of prey organisms
(ICES CM Documents;1977/L:33, Working paper, 1977) -
Weaning trials with cod fry on artificial diets
(ICES CM Documents;1990/F:47, Working paper, 1990)Three experiments with different size groups of cod fry, 13, 49 and 465 mg wet-weight were offered 6 different artificial diets. The experiments lasted for 28 days. Growth, and for the medium size-group chemical composition ...
