The research aimed to determine the effects of some fodder additives (Bio-Mos, Nupro and Sel-plex) on growth and consumption indices, meat quality and survival rate in brook trout. The research has been carried out on a number of 1000 ishes, randomly distributed in 4 groups (250 ish/group): a control group, group 1E (Bio-Mos 0.2%), group 2E (NuPro 2%) and group 3E (Sel-plex 0.03%); the experimental period was 250 days. During the experiment the following parameters were recorded and analyzed:

... dy mass evolution, weight gain, speci ic growth rate, feed conversion ratio (FCR), meat quality and survival rate. The best results were recorded in group 1E (Bio-Mos 0.2%), with a body weight of 248.45 g, a weight gain of 228.45 g and a FCR of 1.18 kg fodder/kg weight gain. The high values of meat Selenium content show the cumulative effect of organic Selenium in the ish meat; as a result, this meat can be considered a functional food. The highest survival rate was recorded in group 3E (95.60%), receiving dietary Selenium supplementation.
