Th is paper evaluates the eff ects of two diff erent feeds on production results and economic performance in the rainbow trout (Oncorhynchus mykiss) farming. Th e fi rst group (O-1) was fed with a standard comple- te pelleted feed, and the second group (O-2) was fed with combined feed consisting of 75 % pellets and 25 % of sardines. Better results were obtained with the O-2 group, while the O-1 group achieved results characteristic for local farming conditions and feed quality. Experimental group O-2 had si- gnifi cantly higher (p<0,01) growth rate when compared to group O-1. Con- sidering current feed and fi nal product (fi sh) prices in the market, better results in terms of cost-eff ectiveness were obtained (E>0,00) in O-2 group of trout fed with the combined meal.
