Ichthyobodosis is an important parasitic disease that has caused severe loss among ornamental and farmed fish world wide for more than a century. The disease is caused by heavy infections on skin and gills by parasitic ...
Competition between marine osmotrophs for phosphorus and nitrogen : implications for the microplanktonic food web
(The University of Bergen, 2007-03-29)
Understanding how competition for nutrients structures the flows of C, N, P, and other elements through the microbial food web may seem central to our understanding of the role and function of this part of aquatic ...
Characterization of ‘Candidatus Syngnamydia salmonis’ (Chlamydiales, Simkaniaceae), a bacterium associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
Two Chlamydiales have previously been found to infect Atlantic salmon (Salmo salar L.), Candidatus Piscichlamydia salmonis and Candidatus Clavichlamydia salmonicola. Both develop intracellularly in cyst-like inclusions in ...
Relationships between spawning ground identity, Latitude and early life thermal exposure in Northeast Arctic Cod
(Journal of Northwest Atlantic Fishery Science, 2008)
from its feeding grounds in the Barents Sea to various spawning banks along the Norwegian coast. Prior to the 1990s these banks were located on a wide latitudinal range from Finnmark (~71º N) to Møre (~63º N), or even ...
Biology and distribution patterns of some deepwater demersal fishes in the North Atlantic, with special reference to Antimora rostrata A study related to the project “Patterns and Processes of the ecosystems of the northern Mid-Atlantic”, MAR-ECO, 2001-2008
(The University of Bergen, 2007-06-19)
