The combined impact of plant-derived dietary ingredients and acute stress on the intestinal arachidonic acid cascade in Atlantic salmon (Salmo salar)
Oxley, Anthony; Jolly, Cecile; Eide, Torunn; Jordal, Ann-Elise O.; Svardal, Asbjørn Martin; Olsen, Rolf Erik (Journal article; Peer reviewed, 2010-03)A study was conducted to assess the effect of substituting high levels of dietary fish oil (FO) and fishmeal (FM) for vegetable oil (VO) and plant protein (PP) on the intestinal arachidonic acid (AA) cascade in the carnivorous ... -

Molecular cloning, characterization and nutritional regulation of key enzymes required for the effective utilization of marine wax esters by Atlantic salmon (Salmo salar L.)
Minghetti, M.; Olsen, Rolf Erik; Tocher, D.R. (Journal article; Peer reviewed, 2010-10)Previous studies had shown that wax ester-rich lipid extracted from calanoid copepods could be a useful alternative to fish oil as a provider of long-chain n-3 polyunsaturated fatty acids in diets for use in salmon ...
