The changes in the fatty acid profile of some tissues of female carp after feeding of vitamin and mineral supplement

Abstract

The problem of vitamin and mineral nutrition of pond fish and its influence on metabolic processes in their organism is a matter of vital importance in the last decades all over the world. The aim of the study was to assess the effect of vitamin and mineral supplement on lipid individual classes and fatty acid composition in the body of female carp in pre-spawning period. For this purpose, lipids were determined after separation by thin layer chromatography and the fatty acid composition by gas chromatography, on 5-7 samples of fish tissues. Vitamin and mineral supplementation of the carp diet leads to the increase of the level of mono- and polyunsaturated fatty acids in the skeletal muscle of female carps from the second experimental group: a significant decrease of palmitic acid to 14.1%, compared to 19.06% in control (P
