(EDP Sciences, 2014-09-12)
A redescription of Protoopalina pingi Nie, 1935 is presented in this paper to complete Nie’s description at both light and scanning electron microscope levels. These organisms were collected from the recta of the frogs ...
The effects of cyanobacteria on the growth, survival and behaviour of a tropical fish (Nile tilapia) and zooplankton (Daphnia lumholtzi)
(The University of Bergen, 2009-10-30)
Recent studies on the ecological effects of cyanobacteria in lakes have focused on the harmful effects of blooms to other aquatic organisms including fish and zooplankton. Much of this work has been conducted on temperate ...
Replacing fish oil by vegetable oil in a low fish protein diet: effects on visceral adipose tissue and inflammation in Atlantic salmon
(The University of Bergen, 2012-06-04)
Dietary fish oil (FO) replacement with vegetable oils in combination with high dietary fish meal replacement have previously been shown to increase Atlantic salmon plasma and liver TAG as well as visceral fat deposition. ...

Geomicrobial characterisation of a 60 m long permafrost core, taken over a future CO2 storage site at Svalbard
(The University of Bergen, 2014-09-11)
In connection with a planned CO2 storage pilot project in the Arctic, a 60 m long permafrost core was drilled in Adventdalen, Svalbard, representing the poorly studied deep permafrost ecosystems. The on-shore drilling was ...
Molecular characterisation of the salmon louse, Lepeophtheirus salmonis salmonis (Krøyer, 1837), ecdysone receptor with emphasis on functional studies of female reproduction
The salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae) is an important parasite in the salmon farming industry in the Northern Hemisphere causing annual losses of hundreds of millions of dollars (US) worldwide. To ...
Interactions of arginine and polyamines on growth and metabolism in Atlantic salmon
(The University of Bergen, 2014-10-09)
Arginine and methionine are indispensable amino acids (AA) for Atlantic salmon, meaning that salmon is unable to produce these AA endogenously and is fully dependent on dietary supply. In addition to be substrates for ...
