ECONOMIC EVALUATION OF RAINBOW TROUT (Oncorhynchus mykiss) FARMING FED WITH DIFFERENT COMPOSITION FEED

Abstract

This paper evaluates the eff ects of two diff erent feeds on production results and economic performance in the rainbow trout (Oncorhynchus mykiss) farming. The first group (O-1) was fed with a standard complete 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 signifi cantly higher (p0,00) in O-2 group of trout fed with the combined meal.
