Their total share exceeds or corresponds to the recommended amount [1]. Palmitic
acid dominates among the saturated acids in silver carp flesh. According to literature
data, there is significantly more palmitic acid in silver carp flesh than in our studies.
The discrepancy between the results of the studies is evidently due to different growing
conditions, weight or physiological state of the fish.

elaidic and palmitooleic acid prevail among the monounsaturated fatty acids
in silver carp flesh.
Indicators of biological efficacy of silver carp flesh lipids are given in Table 4.

The ratio of individual classes of lipids does not correspond to the
recommendations proposed by specialists in nutritional medicine. However, the ratio
of fatty acids C18:2:C18:3 is consistent with the literature data and attests to the high
biological efficacy of carp and silver carp flesh lipids. The ratio of these fatty acids in
silver carp flesh is of great interest, where especially valuable ω

fatty acids
predominate.
