Abstract
Knowledge of the chemical nature of fish oil
fatty acids and their distribution in marine life is
important for the development of fishery products, the
evaluation of the nutritional significance of fatty
acids in fish oils, understanding the physical and
chemical properties and the biochemical role of fatty
acids in fish and marine animals.
Fish and marine oils are generally characterized
by a rather large group of saturated and unsaturated
fatty acids, which are commonly associated with
mixed triglycerides.
Natural oils in marine plant life (Planktonic
crustacea) and other planktons are consumed by fish
in varying degrees depending on feeding habits. Feeding
habits of fish can vary according to such factors
as availability of food, geographic factors, periods
of fasting, and spawning cycles.
The fatty acid distribution patterns of fish
and marine aminal oils are very complex from the stand.
