The Share of Internal Organs and Viscera in Rainbow Trout (Oncorhynchus Mykiss) Reared in Different Growth Systems

In this experiment we followed the influence of growth system on the share of internal organs and viscera by the total body mass on rainbow trout (Oncorhynchus mykiss). The importance of this study results from the need to reach as favourable slaughter yield. For this, were slaughtered 25 rainbow trout from the Fiad trout farm (conventional farm), Bistriţa-Năsăud County (control group – M), respectively 25 rainbow trout grown in a recirculating system arranged in Cluj-Napoca (experimental group – E). Body weight of the studied specimens was 228.96±1.21 g – M group, respectively 229.40±1.24 g – E group, the difference between the two groups being insignificant (p>0.05). The slaughter yield was favorable for E group – 90.55±0.03%, compared with M group – 89.23±0.05% (p
