Characterisation of two vitellogenins in the salmon louse Lepeophtheirus salmonis: molecular, functional and evolutional analysis
(Journal article; Peer reviewed, 2011-05-09)The salmon louse Lepeophtheirus salmonis Krøyer affects a variety of wild salmonoid hosts, but is also an important pest in aquaculture, which is a globally important and rapidly growing industry. Salmon lice have large ... -
Characterization of strains of Vibrio splendidus and V. tapetis isolated from corkwing wrasse Symphodus melops suffering vibriosis
(Journal article; Peer reviewed, 2003-01-22)Two vibrio bacteria pathogenic to the corkwing wrasse Symphodus melops were isolated. Vibriosis-inducing strain LP1 was isolated as the dominanting bacterium in kidney samples of dead and moribund wrasse from a population ... -
Chemoreception in the salmon louse Lepeophtheirus salmonis: an electrophysiology approach
(Journal article; Peer reviewed, 2007-12-13)The search for effective and long-term solutions to the problems caused by salmon lice Lepeophtheirus salmonis (Krøyer, 1837) has increasingly included biological/ecological mechanisms to combat infestation. One aspect of ... -
Comparative susceptibility of turbot, halibut, and cod yolk-sac larvae to challenge with Vibrio spp.
(Journal article; Peer reviewed, 2010-02-24)In intensive aquaculture systems, high mortalities are frequently observed during the early life stages of marine fish. The aim of this study was to investigate differences in the susceptibility of turbot Scophthalmus ... -
