Abstract

The Diclobothrium armatum parasite is one of the monogenean parasites of the Diclobuteridae family and the genus Diclobothrium, which specifically infects sturgeon in natural habitats and cultured conditions. This parasite is a single host, and by affecting the gills of the sturgeon, it causes breathing disorders, and in severe contamination, causes the death of the sturgeon. Identification of the Diclobothrium armatum parasite based on the structural features of this parasite and also considering the occurrence of various behaviors in infected sturgeons, including loss of appetite and extensive injuries with bleeding and anemia in Sturgeon gills are possible. Tissue damage caused by the Diclobothrium armatum includes adhesion in secondary gill blades, degeneration, edema, necrosis, hyperemia, hemorrhage, hyperplasia, and destruction of gill tissues. Considering the decrease in appetite and growth and also the possibility of death in farmed sturgeon infected with the Diclobothrium armatum parasite, it is necessary to prevent the contamination of farmed fish with it in sturgeon farms. Installing suitable filters in the way of water entering the fields from the river and using well water with proper oxygenation at the same time as the water temperature increases are effective in this field. In order to treat fish with the Diclobothrium armatum parasite, the most appropriate treatment method is selected based on the status of fish contamination with the Diclobothrium armatum parasite.
