Centrocestus formosanus (gill fluke) is a trematode parasite that has spread throughout the world as a result of the aquarium fish trade. Its infection causes high fish mortalities and economic losses to fish farmers worldwide. At the University of Kelaniya, researchers investigated the efficiency of an ethanol (95%) extract of the cashew (Anacardium occidentale) apple in controlling C. formosanus infection in swordtail (Xiphophorus hellerii). According to the findings, 340 mg/L cashew apple extract can be utilized to treat this trematode infection in aquarium fish.
