Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2013, Vol 6, Issue 2
Abstract
Due to diversification of salmonid species which are farmed in Romania, the aim of this study was been to determine the production performances of rainbow trout (Oncorhynchus mykiss), Palomino variety, compared with the clasical variety – Irideus. Analyzing the body weight of both varieties at the end of experiment, was recorded a very significant differences (d=16.11 g; p<0.001) in favor of the irideus Variety. Also, very significant differences was recorded regarding other morphological characters (Tl-d=0.93 cm, p<0.001; Sl-d=0.88 cm, p<0.001; Cl-d=1.07 cm, p<0.001), favorable for Irideus variety. Growth indices showed also favorable values for Irideus variety (TG:d=16.05 g, p<0.001; ADG:d=0.041 g, p<0.05). Regarding the body form indices, the differences between the two varieties were generally insignificant, except Fullton Condition Factor (K:d=0.06; p<0.001), this presenting favorable values for Palomino variety, respectively Meat indices 2 (Mi2:d=0.44; p<0.05), being favorable for Irideus variety.
