The effects of grains, pelleted and extruded feed on the fatty acid content
in carp meat has not been examined yet. In this work, we present evidence
that the high carbohydrate content in all three types of feed causes oleic
acid to predominate in all meat samples. A higher PUFA content in the meat of
fish fed with granulated feed was detected. The extruded feed diet led to 69%
greater n-3, and 53% lower n-6 fatty acid contents. Their ratio is thus
2.64-fold higher than in meat of carp fed with pelleted feed. A higher
content of n-3 fatty acids in fish fed with extruded feed was the consequence
of higher DHA (1.6 times) and EPA (3.3 times) contents. The detected
differences could be the consequence of the thermal treatment of extruded
feed that makes the proteins, carbohydrates and lipids more accessible to
fish than in a pelleted feed.
