摘要

Nowadays, salmon has been suggested to be the major human dietary source of n-3 polyunsaturated fatty acids (PUFA) of nutritional and medical interest. However, there is an increased interest in rainbow trout from aquaculture. Information on dietary intake of cholesterol through fish consumption can be important, especially to those with cardiovascular problems. The objective of this study was to compare lipid and cholesterol contents and fatty acid profiles of the lipid fraction of marketable rainbow trout fillets obtained from two fishponds with intensive production situated in Serbia (Ⅰ) and Bosnia and Herzegovina-Republic of Srpska (Ⅱ). Fish samples of similar size and weight were collected in August and September 2010. Fish was fed with formulated feed consisting offish products, oils and fats (Ⅰ) and fish meal, soybean protein products and corn (Ⅱ). Lipid content of fish fillets was determined by standard ISO method. Cholesterol content and fatty acid profile were determined by using HPLC/PDA and GC/FID, respectively. Lipid and cholesterol content in the examined fish were 1.28% and 46.48 mg/100g (Ⅰ) and 4.17% and 70.12 mg/100g (Ⅱ), respectively. Fatty acids profile of rainbow trout fillets from two fishponds (Ⅰ and Ⅱ), quantities of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids (% of total fatty acids) were determined. n-3/n-6 PUFA ratio was 1.53 (pond I) and 1.09 (pond Ⅱ). Our results are discussed in relation to lipid source in fish feeds as the main factor responsible for cholesterol content and fatty acid profile variations in farmed rainbow trout.
