Abstract


The trial was carried out for 35 weeks at the trout farm ICAS Gilau, Cluj County. Three groups were implied: a Control group and two experimental groups (Bio-Mos 0.2 % and SelPlex 0.03 %) each consisting of 250 brook trout juveniles. The experimental groups received 0.2 % Bio-Mos and 0.03% SelPlex. At the end fish reached an average weight of 238.55 g/specimen for experimental group 1 and 212.2 g/specimen for the second experimental group comparatively to the Control group (204.65 g/specimen). The analysis of indices regarding the quantification of the health status, survival and losses, shows the benefical biological effects of the additives that had been incorporated in the basal diet of brook trout. The improvement of gluthation-peroxidase blood level in group 3 (5.63 UGPx/mlPCV) comparative with that registered at the Control group (4.34 UGPx/mlPCV) is another evidence of the biological benefical effects of Selenium. Also there have been a significant improvement of selenium content of brook trout meat, with 287.15 % higher than the Control group (238.99 μg/kg comparative with 61.73 μg/kg) as a response to brook trout diet supplementation with organic selenium. The addition of Bio-Mos and SelPlex in brook trout feed did not have a major impact on the chemical composition of brook trout meat, the differences recorded being insignificant.
