Produkční účinnost technologicky upravených obilovin v chovu tržních kaprů
 MÁSÍLKO, Jan
Common carp (Cyprinus carpio L.) is one of the most important cultivated fish species over the world. In the Czech Republic, the production of carps by pond aquaculture farming has a long tradition and a non-interchangeable appearance in the cultural landscape. The production is mainly executed in semi-intensive systems, were a combination of natural feed with additional feeding of cereals is applied. Mostly all available cereals are used for supplemental feeding. Due to that cereals represent one of the most important economic factors in the business. It is estimated that these cost can be around 30 35% of total costs within the carp farming. A possibility to reduce these costs is to increase the production efficiency of the cereals, using a suitable technological pre-treatment. The chosen technological treatment should be simple, cheap and easy available for the common practice in fishery. This thesis examined technological treatments of cereals. The main management and production data were examined in respective to the economy. Also the possible impact on the environment of different treatmented cereals in pond aquaculture, especially balance of total phosphorus was evaluated as well as the impact of on flesh quality and the textural properties of carp, respectively.
