Effect of river fragmentation and flow regulation on occurrence of landlocked brown trout in a fish ladder
Original language description
The movement pattern of brown trout Salmo trutta (L.) in a fish ladder on the heavily fragmented Ohře River, Czech Republic was observed for 16 months. Some individually- tagged fish repeatedly occurred in the ladder. A total of 1640 fish represented captures of 595 S. trutta in the fish ladder; 247 fish were caught once and 348 individuals were caught repeatedly. Repeatedly-caught (348) individuals represented 1393 (84.9%) of the 1640 captures. The likelihood of repetitive occurrence decreased with theincrease in fish body length. The number of individuals in the ladder was inversely related to temperature, and positively correlated with increasing water flow in the main channel. Fish abundance in the ladder was density-dependent, as the number of individuals was inversely related to fish size and time of residency in the ladder.
