Failure of two consecutive annual treatments with ivermectin to eradicate the reindeer parasites (Hypoderma tarandi, Cephenemyia trompe and Linguatula arctica) from an island in northern Norway.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2002)
The highly efficient endectocide ivermectin is used to reduce the burden of parasites in many semidomestic
reindeer herds in northern Fennoscandia. In the autumn of 1995 and 1996 all reindeer on the island of Silda (42 km2)
were treated with ivermectin in an attempt to eradicate the warble fly (Hypoderma (=Oedemagena) tarandi (L.)), the nose
bot fly (Cephenemyia trompe (Modeer)) (Diptera: Oestridae) ...

Management of reindeer husbandry in Norway – power-sharing and participation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008)
Many governments have come to realize that the best way to manage natural resources is to include the resource users in order to increase legitimacy for governance. For the Sami reindeer industry, the Norwegian government has implemented two different management models in order to meet this challenge. On the one hand, there is a corporative management model where a few democratically elected reindeer ...
Whirly proteins as communicators between plant organelles and the nucleus?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
Whirly proteins belong to a small family of proteins with a characteristic secondary structure and a conserved DNA binding domain that is found mainly in angiosperms. At least one member of the Whirly protein family, Whirly1, is dually targeted to the nucleus and to the chloroplasts and it was shown that apart from its initially described function as a transcriptional regulator of nuclear disease ...
Haematological and physiological characteristics of diploid and triploid sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005)
The purpose of this study was to determine whether diploid and triploid sea bass differed in terms of main haematological and physiological characteristics. Diploid and triploid fish were produced by sub-optimal pressure treatments and held in communal environments under standard rearing conditions. Total red blood cell count (RBCC), haemoglobin concentration (Hb), hematocrit (Hct), mean cell volume ...
Vertical movements of Atlantic salmon postsmolts relative to measures of salinity and water temperature during the first phase of the marine migration
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
The migratory behaviour of hatchery-reared Atlantic salmon, Salmo salar L., post-smolts during the
first phase of the marine migration was examined to assess their susceptibility to salmon lice, Lepeophtheirus
salmonis (Krøyer), infestations. Swimming depths of eight post-smolts relative to the measured salinity and
temperature were monitored for an average of 11.4 h following release outside the ...
Genetic investigation of swimbladder inflation anomalies in the European sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
Although the aetiology of swimbladder inflation anomalies in important aquaculture species such as European sea bass D. labrax is not fully determined, culture conditions are commonly suggested as main contributory factors. Little information is available on whether swimbladder inflation has a genetic basis for its expression too. In this work, 24 full-sibling sea bass families from a 4 dams x 6 ...
Induction of tetraploid gynogenesis in the European sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2003)
A preliminary study on tetraploid gynogenetic induction in the European sea bass was performed by pressure-blocking the second polar body release and the first cleavage in eggs fertilized with ultraviolet-irradiated sperm. Fertilization of eggs with genetically inactivated sperm produced only haploid development that terminated around hatching. Pressure treatments (8.500 psi for 2 min) applied at 6 ...
A shortcut method for sexing juvenile European sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005)
The objective of this study was to develop a rapid and effective method of sexing juvenile sea bass with minimum labour and material.To this end, the gonad squash mount technique was applied along with macroscopic techniques for sexing a large number of experimental fish at the age of 215-275 days post fertilization (p.f.). At this age, 90% of the 3894 fish could be unambiguously sexed by ...
