THE INFLUENCE OF NUTRATIVE LIPID SOURCES ON THE GROWTH AND CHEMICAL AND FATTY ACID COMPOSITION OF CARP (CYPRINUS CARPIO L.)
Institute of Fisheries and Aquaculture – Varna, Plovdiv Branch, Bulgaria
ABSTRACT. The purpose of the present study was to determine the influence of animal and plant lipids (cod-liver, soybean and sunflower-seed oil, sunflower-seed and tallow fatty acids, sunflower-seed lecithin) on the growth and chemical and fatty acid composition of carp, Cyprinus carpio L. Eight isocaloric diets that were processed into granules and distributed in three experiments were used. The nutritive lipid sources that were a component of the carp diets stimulated growth, protein absorption, and the retention of fats and protein. The fatty acids extracted from the carp in the 2+ age group were either oleic-linoleic-palmitic or oleic-palmitic-linoleic. The individual fatty acid profile was influenced by the composition of the lipid sources.
Key words: CARP (CYPRINUS CARPIO), NUTRITION, LIPIDS, GROWTH, BIOCHEMICAL PARAMETERS, FATTY ACID COMPOSITION
