Infectious salmon anaemia (ISA) epidemiology in Norway.
TLDR
The findings indicate that a prompt eradication policy and improved biosecurity would be important means of controlling ISA and that decreased host resistance could be important. Expand
Phytoplankton of Norwegian coastal waters
Morphology and taxonomy of toxic species in the tamarensis group (Dinophyceae): Alexandrium excavatum (Braarud) comb. nov. and Alexandrium ostenfeldii (Paulsen) comb. nov.
TLDR
Based on observations on infraspecific variations it is proposed that the genus concept of Alexandrium HALIM is extended to include species with direct contact between the plates Po and 1′ and the new combinations Alexandrium excavatum (BRAARUD) comb. Expand
Thoracosphaera heimii (Lohmann) Kamptner is a dinophyte: Observations on its morphology and life cycle
TLDR
The planospore morphology and the dinocaryotic nucleus demonstrate that T. heimii is a dinophyte and not a coccolithophorid and a new order Thoracosphaerales Tangen, ord. nov. is proposed for primarily coccoid marine dinoflagellates that possess a calcified cell wall in the vegetative life phase.

INTERSPECIFIC VARIATION IN DARK NITROGEN UPTAKE BY DINOFLAGELLATES 1
TLDR
This study emphasizes the variability of dinoflagellate nitrogen nutrition and illustrates the difficulty of associating mass occurrences of din of lagellates in nature with any particular nutritional mode. Expand
Blooms of Gyrodinium aureolum (Dinophygeae) in North European waters, accompanied by mortality in marine organisms
Abstract Mass occurrence of the dinoflagellate Gyrodinium aureolum Hulburt in coastal waters on the Norwegian south-west coast in the autumn 1976 was accompanied by fish mortality in floating netExpand
An outbreak of paralytic shellfish poisoning in western Norway
TLDR
An outbreak of paralytic shellfish poisoning PSP occurred earlier in the year than in previous cases reported in Norway, and represents a very early detection of PSP in mussels from the geographical area considered. Expand
PIGMENTATION AND MORPHOLOGY OF A MARINE GYRODINIUM (DINOPHYCEAE) WITH A MAJOR CAROTENOID DIFFERENT FROM PERIDININ AND FUCOXANTHIN 1
TLDR
The preliminary results indicate that this Gyrodinium may be a previously undescribed species, which possessed three xanthophylls that could not be correlated with carotenoids previously reported from dinoflagellates. Expand
Shellfish poisoning and the ocurrence of potentially toxic dinoflagellates in Norwegian waters
Phytoplankton observations in Oslofjorden during the last years indicate that the potentially toxic dinoflagellates Gonyaulax excavata, Procentrum minimum, Gyrodinium aureolum and DinophysisExpand
