Main purpose of this diploma work was to find out possibility using PIT telemetry in monitoring strange crayfish species Spinycheek crayfish Orconectes Limosus. Research of the theme consisted of three steps: two laboratory researches and one research in the natural environment. The first laboratory study concerned tagging passive integrated transponder (PIT) to various part of crayfish body. PIT tags were internally implanted to cephalothorax, abdomen and claw. The highest mortality was in tagging to claw. The second laboratory research consisted of comparing different tagging methods to PIT telemetry. Crayfish were tagging by PIT telemetry, soldering, visible implant elastomers and visible implant Alpha tags. Among tagging groups there were not to find out different in mortality. In the third research the crayfish were tagging in their natural environment. There were using three methods: PIT telemetry, soldering and VI Alpha tags. This experiment wasn´t successful. During recapturing crayfish there were not to find any tagging crayfish.
