IntroductionTrout farming is a specifi c branch of agriculture, requiring a wide range of knowledge of fi sh behav-ior and the aquatic environment. Solid knowledge in this case is the most important factor for success. Only on the basis of a broad knowledge of specifi c breeding technology and its fi nal product can trout breeders manage and develop their farms. The interdisciplinary database presented hereby follows this direction based on the scientifi c research of rainbow trout production in the Polish reality.Currently, there is a need for expertise in the production of this sector of the economy because aqua-culture is the most intensively developing branch of agricultural production in the world. This increase is largely due to increased salmonid production. This is possible on one hand due to health-related prop-erties of fi sh meat, and on the other hand to the signifi cant potential for agricultural production. Rain-bow trout is in second place (after Mediterranean Blue Mussel) among the 10 main species produced in European aquaculture and in fi rst, when it comes to fi sh. In Poland in 2011, the total sales volumes of all species of trout were high. The rainbow trout ratio of 96.3% amounted to 11 663 tons.
