Název v původním jazyce

The effect of water level fluctuation on tributary spawning migration of reservoir fish

Popis výsledku v původním jazyce

The Rímov Reservoir (Czech Republic) was chosen as a model object to study the importance of the tributary zone (Malše River) for the fish populations of the reservoir. The migrating fish were captured by two specially constructed large fykenets during four seasons 2000 - 2003. One trap was sampling upstream- and the second one was sampling downstream- migrants. The spring spawning migration of cyprinids was found as the most important event of every season and the number of migrating individuals of individual fish species corresponded to the total abundance in the reservoir and to affinity of individual fish species to the spawning in the tributary area of the reservoir. During first three seasons, the water level had a similar pattern with maximum level in the beginning of spring and flooded terrestrial vegetation was available for phytophilic fish to spawn along the shoreline of whole reservoir. In 2003, the water level was maintained down by at least 2 m and no plantspawning substr
