| Description
| - Výskyt raka pruhovaného byl v České republice poprvé zaznamenán v 80. letech 20. století v řece Labi kam se dostal migrací proti proudu ze SRN. Jeho hojný výskyt byl potvrzen i na dalších lokalitách ČR. Jeho migrační schopnost byla experimentálně studována 30-komorovém rybím přechodu ve vodní elektrárně na řece Labi. Skupinově označení raci byli nasazováni do 3 vybraných komor. Byl zjišťován jejich pohyb po a proti proudu po 30 min po vysazení. Bylo zjištěno, že většina z vysazených raků se nechala pasivně unášet proudem vody a byla slovena až nejspodnější komoře. Zároveň byla ale zjištěna velká schopnost raků udržet se ve velkém proudu vody na stejném místě. V žádném případě nebyl zaznamenán pohyb raků proti proudu vody do výše položených komor. V průměru 56.7#9.43%, 6.7#9.43% a 3.3#4.71% raků zůstalo v komoře kam byli vysazeni a 23.3#4.71%, 30.0#14.14% a 26.7#17.00% raků migrovalo do níže položených komor. (cs)
- The occurrence of the spiny-cheek crayfish in the Czech Republic was first reported in the 1980´s in the Elbe River and is a result of its upstream migration from Germany. This study confirms that this species occurs in many other localities across the Czech Republic. Its migration ability was experimentally studied at a thirty-chambers fishpass located at a hydro-electric power station in the Elbe River. Group-marked crayfish were placed into 3 selected chambers. Their up- and downstream movement was then registered for 30 min after crayfish stocking. We found that a large portion of the experimental crayfish was passively carried along the stream and was caught in the lowest chamber. The movement of crayfish against the water current towards the higher-positioned chambers was not recorded. However, crayfish showed to have a high ability to hold their position in a strong water flow. Overall, 56.7#9.43%, 6.7#9.43% and 3.3#4.71% of crayfish remained in the chamber of insertion and 23.3#4.71%, 30.0#1
