It is the sad fact, that in the Czech Republic, consumption of fish is very low compared with the European Union average, but, at the same time, it belongs to the countries with the highest incidence of cardiovascular diseases. Sufficient intake of n-3 poly-unsaturated and highly-unsaturated fatty acids (n-3 PUFA and HUFA) is important in preventing and treating cardiovascular disease. Fish is the main source of these compounds in the human diet. This thesis examined factors influencing n-3 PUFA and HUFA levels in fish lipids and ways of increasing the n-3 fatty acid (FA) content in freshwater farmed fish.First, production of common carp (Cyprinus carpio L.) with defined flesh quality using a finishing feeding strategy and prediction of fillet FA by a dilution model were investigated, the effects of purging on lipid content and fillet quality of common carp in Central Europe were examined in fish kept for up to 70 days in clear water without feeding; and changes caused by frying on fat uptake, fatty acid composition and oxidation in the fillet of carp with increased n-3 fatty acid content were examined using four different fats to fry either plain or battered fillet.
