A biotest system for optimalization of environmental parameters for production of halibut fry
Mangor-Jensen, Anders; Jelmert, Anders; Naas, Kjell Emil; Harboe, Torstein; Skiftesvik, Anne Berit (ICES CM Documents;1987/F:21, Working paper, 1987)A system for controlled testing of different environmental parameters in seawater was made. Both the biotest system and an experimental setup using larvae of the Atlantic Halibut (Hippoglossus hippoglossus L.) are described. -
A comparison of growth rate of halibut larvae (Hippoglossus hippoglossus L.) fed wild zooplankton and enriched Artemia
Skjolddal, Lillian; Harboe, Torstein; Næss, Tore Håkon; Naas, Kjell Emil; Rabben, Håvard (ICES CM Documents;1990/F:60, Working paper, 1990)Halibut larvae at an age of 267 day degrees post hatching, were reared through first feeding, outdoors in 100 l plastic bags. There were three feeding regimes: wild zooplankton, Artemia enriched on the algae Isochrysis ... -
A pilot study of halibut larvae (Hippoglossus hippoglossus L.) reared from start feeding to metamorphosis on diets of wild zooplankton and Artemia
Boxaspen, Karin; Harboe, Torstein; Skjolddal, Lillian (ICES CM Documents;1990/F:52, Working paper, 1990)Halibut larvae ready to start feed were placed in two outdoor tanks of 7 m^3. The larvae in one tank were fed wild zooplankton throughout the whole period, and the larvae in the other tank were fed wild zooplankton from ... -
Age of Atlantic halibut larvae (Hippoglossus hippoglossus L.) at first feeding
Harboe, Torstein; Næss, Tore Håkon; Naas, Kjell Emil; Rabben, Håvard; Skjolddal, Lillian (ICES CM Documents;1990/F:53, Working paper, 1990)Halibut larvae at different age (150 to 315 day-degrees) were transferred to outdoor startfeeding tanks each with two internal plastic bags (100 litre). The larvae were fed wild zooplankton. One bag was sampled after 24 ... -
Green water in larviculture - An experiment with natural phytoplankton in tanks for first feeding of halibut larvae (Hippoglossus hippoglossus L.)
Næss, Tore Håkon; Bergh, Øivind; Harboe, Torstein; Naas, Kjell Emil; Rabben, Håvard; Skjolddal, Lillian (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 ... -
Incubation of halibut yolk sac larvae improved by addition of freshwater and oxygen
Holm, Jens Christian; Naas, Kjell Emil; Harboe, Torstein; Skår, Sjur Åge (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 ... -
A new cleaning system for rearing tanks in larval fish culture
van der Meeren, Terje; Harboe, Torstein; Holm, Jens Christian; Solbakken, Roar (ICES CM documents, Working paper, 1998)
