Linseed oil as a substitute for fish oil in the diet of Arctic charr (Salvelinus alpinus), brook charr (S. fontinalis) and their reciprocal hybrids.
This study examines the potential effects of linseed oil as a total replacement for fish oil in the formulated diet of Arctic charr, brook charr and their reciprocal hybrids. Muscle fatty acid composition, growth performance and feed utilization were evaluated on four experimental groups submitted t...

Muscle fatty acid composition, growth performance and feed utilization were evaluated on four experimental groups submitted to two different dietary lipid sources (100% linseed oil or 100% fish oil). Growth performance, feed utilization, muscle lipids and protein content were not affected by dietary linseed oil. Lipid source significantly affected muscle fatty acid profile. The replacement of fish oil by linseed led to an average reduction in 20:5n3 and 22:6 n3 (25.5% and 18.4% respectively) and an increase in 18:3n3 (177%) (mean values calculated for the four experimental groups).
