Disease caused by the parasitic helminths Dactylogyrus spp. results in significant economic damage to the aquaculture industry. Treatment using common chemicals (e.g. formalin) is usually dissatisfactory due to environmental problems, risk of residues, toxicity to fish, and the possibility of anthelmintic resistance. The search for an alternative drug is thus becoming more urgent. This study wa...

In 5 experunents, conlmon carp fry Cyprinus carpio with Dactylogyrus vastator infection of varying severity, as well as parasite-free fry, were placed into an environment of decreasing oxygen content. The correlation between the time of death and helminth infestation of the gills was studied. The experiments demonstrated that in a medium of decreased oxygen content the carp with the heaviest he...
