The growth of brown trout (Salmo trutta, L.) in Blanice river and its tributaries
 BALCAR, Jakub
The aim of the study was to compare the growth of brown trout in the river Blanice and its tributaries - Živný brook during the growing season 2013. Due to unfavorable hydrological situation in the Blanice river was used data about the growth of brown trout in a defined section of the river, obtained during an experiment in 2007.Tagged fish were divided into three size categories: small juvenile, large juvenile and adult fish.The specific growth rate of all groups of fish from the Živný brook was higher than in the same groups of fish in Blanice river. Significantly higher growth rate of small juvenile fish compared to the groups larger fish was also demonstrated in the Živný brook. The results show that the growth rate of brown trout mainly depends on the nutrient (food) content of the flow, rather than its size or population density of brown trout.
