The aim of this graduation thesis is evaluation results of trout culture and make proposition new improved technologic process in fish farming on this site. The thesis also includes experiments with initial feeding of fry of brown trout (Salmo trutta morpha fario) carryed out during the spring 2008. The main observed values were survivance, specific growth rate (SGR) and feed conversion ratio (FCR). After 17 weeks of initial feeding fry of brown trout the observed values were achieved: survival of fish 38,2 % , average length SL = 69,0 mm, average weight 4,9 g.
