Factors affecting migrations of burbot
Original language description
In autumn, burbot Lota lota migrations through a fish ladder in the regulated Ohre River, Czech Republic, were stimulated by an increase in discharge and a decrease in water temperature but the number of burbot in the ladder was significantly lower whencompared with other seasons. The maximum number of burbot in the ladder was recorded in spring when discharge decreased. A sudden decrease in water level caused burbot to leave the refuges in the riverbanks that they had occupied during high winter dischnter discharges. The results indicate that the relatively low short-term variability of physical conditions represented by the modified discharge regime can induce a stronger response in fish migrations even in comparison with typical reproductive migrations of these species.
