The monogenean Gyrodactylus gasterostei and its host, the three-spined stickleback Gasterosteus aculeatus, were employed as a model system to investigate the influence spidertattooz.com of gyrodactylid maturity on host transfer.Laboratory experiments included the determination of maturity (presence of a male copulatory organ) and reproductive status (presence of a daughter parasite) of the transmitting worms.Parasites with a male copulatory organ were more likely to abandon the host and attempt a host transfer.Additionally, in vivo video observation suggested that detached worms employ water turbosound ts-18sw700/8a turbulence to assist their effective transfer onto a new host.
