Abstract

From fish are important for human consumption only certain body regions. From trout we are interested by the muscular tissue which has the greatest proportion. The purpose of this research is to analyze the development of body and cutting reports Oncorhynchus mykiss species of different ages (one year, two year and three year). The best efficiency at slaughter yield, respectively 82.15% was recorded at the third batch of rainbow trout, while at the first batch we obtain the lower 78.96%. Setting component parts indicate an increase of the trunk beside total body weight, at a rate of 66.63% for trout aged 1 year to 72.69% at 3 years old trout. Visceral mass accounted for 18.45% of trout with a yearling trout beside 14.25% at 3 years old. Visceral mass accounted for 18.25% at aged 1 year trout beside 14.45% at 3 years old trout.
