The Movement Patterns of Austropotamobius torrentium and Astacus astacus: Is a Stony Step a Barrier?

Popis výsledku v původním jazyce

Austropotamobius torrentium and Astacus astacus ) are endangered crayfish species in Europe. Artificial barriers represent one option for halting the spread of nonnative crayfish species. In Bzovský Stream (Czech Republic, Central Bohemia) the streambedcontains stony steps placed to decrease the flow of water. Two stony steps (60 cm and 110 cm high) were evaluated as a movement barrier for crayfish. At the area of confluence of Bzovský and Stroupinský streams, 1887 crayfish were marked with a visible implanted elastomer, whereas 56 recaptured crayfish were marked in Bzovský Stream. In a four-year mark-recapture study, we showed that A. torrentium was able to cross a step 60 cm high and that both A. torrentium and A. astacus were able to cross a perpendicular stony step 110 cm high. These results show that these stony steps do not act as strong movement barriers for crayfish in streams. However, the ability of crayfish to move across a concrete barrier appears to depend on the design o
