Physiological responses of over-wintering common carp (Cyprinus carpio) to disturbance by Eurasian otter (Lutra lutra).
Original language description
Using a tame animal, the impact of otter (Lutra lutra) disturbance on over-wintering carp (Cyprinus carpio) was monitored in two experiment, 133 and 140 days, respectively, over two consecutive winters (November-April). The analysis of blood and tissue samples of experimental fish showed changes in nitrogen, carbohydrate and mineral metabolism as well as levels of hormones and fat reserves. Higher response to stres in metabolism of carp with lower intensity of disturbance by otter suggests that high level of disturbance can lead to metabolic adaptation of carp to stres. The effect of stres on the mortality rate of carp during the over-wintering is not clear. Nevertheless, the negative effect of stres on survival, condition and growthn rate of carp in the subsequent vegetation period was not observed.
