Green water in larviculture - An experiment with natural phytoplankton in tanks for first feeding of halibut larvae (Hippoglossus hippoglossus L.)
(ICES CM Documents;1990/F:61, Working paper, 1990)At 232 day degrees, halibut larvae were transferred from indoor tanks to 1.7 m^3 outdoor tanks for first feeding. The number in each tank was approximately 750. Three tanks were continuously given algal suspension ("green ... -
Grid-sorting of penned saithe
(ICES CM Documents;1992/B:11, Working paper, 1992)Size selection of penned saithe was obtained by forcing the fish against an adjustable grid mounted in the end of net pens. The size selection was rather sharp, with a selection range of about 5 cm only. All fish forced ... -
Growth and seawater adaptation in Atlantic salmon (Salmo salar) raised at different experimental photoperiods
(ICES CM Documents;1976/E:39, Working paper, 1976)A study was made of the effect of day length and feeding-time on the smolting process and on growth of Atlantic salmon during smolting. The experiment consisted of five experimental groups with different day lengths. Highest ... -
Growth of juvenile halibut (Hippoglossus hippoglossus L.) in captivity
(ICES CM Documents;1986/F:20, Working paper, 1986)The growth and substrate preference of collected wild juvenile halibut under culture conditions were investigated. The size of the collected fish conformed well with year class data from earlier studies. Halibut growth ... -
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 ... -
Growth rates in cultured common wolffish (Anarhicahas lupus) and spotted wolffish (A. minor)
(ICES CM Documents;1990/F:2, Working paper, 1990)Field caught common wolffish (Anarhichas lupus) and spotted wolffish (A. minor) have been raised from fry on dry pellets. The two species have experienced annual fluctuations in temperature between 6 and 12 °C and the ... -
Halibut behaviour as a means of assessing suitability of ongrowth systems
(ICES CM Documents;1998/L:4, Working paper, 1998)Halibut behaviour in net pens has been studied using direct observation, underwater video and/or hydroacoustic equipment. Rearing experience includes a wide range of fish weights (50-10.000 g) and fish densities (4-150 ... -
Hatching of Atlantic salmon (Salmo salar) in an artificial substrate

Hydroacoustic detection of food waste - a method to estimate maximum food intake of fish populations in sea cages
(ICES CM Documents;1990/F:7, Working paper, 1990)A linear relationship between echo energy and amount of salmon dry food was established. Measurements were carried out both for food batches (5-400 gram) and single pellets. For a certain amount of food, the echo energy ... -
ICES ad hoc working group on interaction between grey seal populations and fish species : Charlottenlund, Denmark, 14 - 18 May 1979.

Illumination in first feeding tanks for marine fish larvae
(ICES CM Documents;1992/F:6, Working paper, 1992)Illumination levels were measured in three artificially illuminated tanks: a black tank, a white tank and a tank with black sides and white bottom, in order to test how well normal tank illumination in different tank ... -
Import of furunculosis to Norway with Atlantic salmon smolts from Scotland
(ICES CM Documents;1987/F:8, Working paper, 1987)In early summer 1985 the Norwegian Veterinary Authorities authorized the import of about 250.000 Atlantic salmon smolts from a fish farm at the west coast of Scotland to the Namdal region north of Trondheim. Immediately ... -
Incubation of halibut yolk sac larvae improved by addition of freshwater and oxygen
(ICES CM Documents;1998/L:14, Working paper, 1998)Halibut fry has been produced regularly by scientific and commercial institutions since late 80- ties. The yearly number of halibut fry produced have, however, not fulfllled the optimistic expectations. This could partly ... -
Indication of high natural mortality for juvenile herring from acoustic and tagging data.
(ICES CM Documents;1980/H:62, Working paper, 1980)Natural mortality for juvenile herring (Norwegian Spring spawners) is discussed on the basis of following data: 1. Acoustic estimates of the 1975 and 1976 yearclasses of herring as 0-group and estimates from tagging ... -
Induced deformities on larvae of the Atlantic halibut (Hippoglossus hippoglossus L.). A new experimental approach.
(ICES CM Documents;1990/F:45, Working paper, 1990)Introduction: The atlantic halibut is viewed as a promising species for cold water aquaculture, and have been subjected to extensive research efforts both in Norway and in U.K. the later years. As the biology, and ... -
