Final report on ichthyologic work under the project C. J1620240 in 2016.
 Kubečka, Jan ; Matěna, Josef ; Čech, Martin ; Blabolil, Petr
Young-of-the-year pike fry was stocked artificially along the left bank of the reservoir Švihov in May 2016. In July 2016 fingerlings inhabited mostly the shallowest littoral. Densities ranged from 1 to 2 pc 100m coast in the dam part into 7-8 pieces per 100 m of the coast in the middle part. Sampling pike fingerlings in the littoral zone has a high efficiency (estimate 84%). Any other observations (installing traps, scuba diving, sampling electrode farther from shore) show that pike fry did not occur at greater depths than most shallow littoral to about half a meter. The densities of fry at the right and left bank of the reservoir apparently did not differ. Even very small pike are probably able to swim across the large reservoir. Of the 81 individuals of pike fry with food 77.8% had a fish prey, and 17.3% had insect larvae in the gut.
