| Abstract: | - 1.1. Cod, 2.6–3.4 kg. were fed a mixed diet of sprat, capelin oil and wheat flour.
- 2.2. Lipids from the feed, stomach and four intestinal segments were separated into tri-, di- and monoglycerides and free fatty acids and analysed by GLC.
- 3.3. All lipolytic products were concentrated in 14:0, 16:0 and 18:0, up to 60% and extremely low in the ω-3 fatty acids.
- 4.4. Residual triglycerides contained 80% of saturated and monoenoic fatty acids.
- 5.5. Linoleic acid increased from 2% in feed TG to 10% in TG of the rectum.
