Abstract

The main goal of this research was to determine some qualitative properties of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) from an aquaculture facility – salmonid fishpond which is situated in Demir Hisar region (Republic of Macedonia). The qualitative properties of the rainbow trout are established by determination of the chemical composition of the fish meat, the energy value of the meat and the microbiological analysis for the total number of microorganisms on fish skin and presence of Salmonella sp. and Listeria monocytogenes. The main purpose of the research produced additional analyzes that determine the chemical composition of food used for feeding of the rainbow trout, the condition factor (CF) and the feed conversion. The results obtained during the examination of the chemical composition (%) of the rainbow trout meat from this fishpond determined the mean value of 71.70 ± 1.003 water, 20.40 ± 1.268 protein, 5.63 ± 0.555 fat and 1.21 ± 0.157 ash. The energy value of the meat was 568.941 kJ/100 g.
