Oil from transgenic Camelina sativa containing over 25 % n-3 long-chain PUFA as the major lipid source in feed for Atlantic salmon (Salmo salar)
Betancor, Mónica B.; Li, Keshuai; Bucerzan, Valentin S.; Sprague, Matthew; Sayanova, Olga; Usher, Sarah; Han, Lihua; Norambuena, Fernando; Torrissen, Ole; Napier, Johnathan A.; Tocher, Douglas R.; Olsen, Rolf Erik (Journal article; Peer reviewed, 2018)Facing a bottleneck in the growth of aquaculture, and a gap in the supply and demand of the highly beneficial n-3 long-chain PUFA (LC-PUFA), sustainable alternatives to traditional marine-based feeds are required. Therefore, ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
Skern-Mauritzen, Rasmus; Torrissen, Ole; Glover, Kevin A. (Journal article; Peer reviewed, 2014-03-14)Background The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -
pH adjustment of acid water at Matre Aquaculture Station: Experiences with previous and existing methods
Ulgenes, Yngve; Hansen, Tom; Torrissen, Ole (ICES CM Documents;1984/F:28, Working paper, 1984)The water from Matre River is characterized as very soft, with a total hardness of 1. 5 - 2. 5 mg Ca0/1 and a very low buffer capacity. Acid precipitation results in low pH, values below 5. 0 are recorded every year. ... -
Physiological changes in blood and seminal plasma during the spawning period of maturing rainbow trout held under different temperature and salinity regimes, and the effect on survival of the broodstock and the eyed eggs
Albrektsen, Sissel; Torrissen, Ole (ICES CM Documents;1988/F:3, Working paper, 1988)Maturing rainbow trouts reared in sea cages were transferred to tanks and kept under nine different temperature and salinity regimes. Blood and seminal fluids were regularly sampled from the fish, and different organic ... -
Pigmentation of salmonid - a comparison of astaxanthin and cantaxanthin as pigment sources for rainbow trout
Torrissen, Ole (ICES CM Documents;1985/F:24, Working paper, 1985)Rainbow trout were fed a diet supplemented with astaxanthin and cantaxanthin. The ratios of astaxanthin to cantaxanthin were determined in plasma, faeces and flesh. During 65 days of feeding the flesh reached a level ... -
