摘要: Abstract The efficacy of the anthelmintic Praziquantel in removing monocotylid monogeneans (Platyhelminthes) from branchial tissue (Neoheterocotyle rhinobatidis, N. rhynchobatis, and Troglocephalus rhinobatidis) nasal (Merizocotyle icopae) juvenile giant shovelnose rays Rhinobatos typus Heron Island, Australia, was studied. Although effective vivo skin gills teleost yellow stripey Lutjanus carponotatus same locality, two 2-h treatments using 20 mg/L ineffective for ray. Adult monocotylids were removed, but many post-oncomiracidia some juveniles remained attached. Juvenile adult rhinobatidis T. reacted similarly when exposed to during vitro experiments, exhibiting muscle contractions dying after 12 14 h, respectively. We attribute failure remove small monogenean stages structure tissu...
