Ichtiofauna cieków prowadzących wodę na terenie Rybackiej Stacji Doświadczalnej UR w Krakowie

While the ichthyofauna of Polish rivers is relatively well documented, few data are available on the ichthyofauna in running streams on fish farms. The present study focused on three streams at the Experimental Fisheries Station of the University of Agriculture in Krakow. During ten catches conducted from March 2011 to March 2012, a total of 626 fish belonging to 16 species were caught. Stone moroko, Pseudorasbora parva, which is an invasive alien species, was also noted. A brown trout spawning nest was observed in one of the streams. This indicates the important role of such ecosystems in preserving biodiversity.
