dcterms:description
Během výzkumu biologie populací invazního raka pruhovaného v ČR bylo zaznamenáno několik případů epibiós na tomto raku. (1) V roce 2001 jsme zaznamenali velký výskyt původní druhů branchiobdell (Annelida: Branchiobdellidae) na racích v řece Labi v Obřiství (střední Čechy). Na racích byly identifikovány 4 druhy, a to: B. pentodonta (52%), B. balcanica (24%), B. parasita (18%) a B. hexodonta (6%). V roce 2003 byl na stejné lokalitě odchycen pouze jeden jedinec s výskytem branchiobdelly (5 jedinců B. parasita). Od té doby již nebyl výskyt branchiobdelly u tohoto druhu raka zaznamenán. (2) Zatopený lom Lhota poblíž Brandýsa nad Labem je jediná lokalita, kde byla zaznamenána kolonizace Dreissena polymorpha (Mollusca, Bivalvia) na těle raka O. limosus. (3) Samice kapřivce Argulus cf. foliaceus (Crustacea: Branchiura) kladou vajíčka na jakýkoli tvrdý substrát, včetně račí exoskeleton. Ve výše zmíněném lomu bylo zaznamenáno 65 % raků s vajíčky kapřivce na povrchu těla. (4) Kolonie Plumatella repens byly nale Several cases of epibiosis by macro-invertebrates on Orconectes limosus were recorded during our research on the biology of populations of this invasive crayfish species in the Czech Republic. (1) In 2001, we observed a high infestation of O. limosus by native species of branchiobdellidan worms (Annelida: Branchiobdellidae) in the river Elbe at Obříství (Central Bohemia). Four European Branchiobdella species were collected and identified from three crayfish specimens: B. pentodonta (52%), B. balcanica (24%), B. parasita (18%) and B. hexodonta (6%). In 2003, only a single crayfish was found bearing branchiobdellidans (5 specimens of B. parasita only) in the same locality. No branchiobdellidans on O. limosus have been confirmed since. (2) A flooded sandpit Lhota near Brandýs nad Labem is the only Czech locality where the settlement of Dreissena polymorpha (Mollusca, Bivalvia) on an O. limosus body was recorded. The crayfish lost the bivalves by moulting in summer; new mussels had settled by late summer Several cases of epibiosis by macro-invertebrates on Orconectes limosus were recorded during our research on the biology of populations of this invasive crayfish species in the Czech Republic.
