Investigating contamination with external and internal parasites in ornamental freshwater angelfish (Pterophyllum scalare)

One of the main reasons the ornamental fish business suffers financial and health losses is parasitic diseases. Consequently, more than ever, research into the incidence and varieties of parasites in various regions of the country is required to identify parasites and prevent their spread across the country examining the ectoparasites and endoparasites of Angelfish (Pterophyllum scalare) was the goal of this study. ۱۰۰ freshwater Angelfish specimens were checked for macroscopic and microscopic parasites. Wet smears were taken from the skin, fin and gills and then evaluated under a light microscope. Following the autopsy, the internal organs were examined with a light microscope. The parasites were stabilized, stained and identified using standard methods and diagnostic criteria. Among ۱۰۰ fish samples, ۷۱% were contaminated with parasites and ۲۹% were not infected. ۲۸% of the affected fish were concurrently contaminated with both Hexamita sp. and Capillaria sp. ۶% of fish were contaminated with Hexamita sp., Capillaria sp. and Ichthyophthirius multifiliis. ۱% were contaminated with Ichthyouris sp. and Hexamita sp. The other infected fish hosted a singular type of parasite. The parasites identified in this study were Trichodina sp. (۳%), Ichthyophthirius multifiliis (۶%), Monogenea sp. (۱۰%), Camallanus sp. (۲%), Capillaria sp. (۶%) and Hexamita sp. (۹%). Research conducted in several countries shows that ornamental fish are infected with both ectoparasites and endoparasites. Considering the widespread commerce of these fish and their movement across borders, there is a risk of transmitting new parasitic fauna, which can pose a threat to local fish populations, particularly those that are valued, rare, or endangered.
