Prevalence and intensity of endoparasitic helminth on swamp eel (Monopterus albus) from natural caught and cultivation

Swamp eel (Monopterus albus) is one of the highly prospect freshwater fisheries commodities that are consumed by broad community. Marketed swamp eels are generally derived from natural caught and cultivated eels. Natural caught swamp eel has high risk of infected parasites from a natural feed that contaminates with larvae of the parasite of cultured swamp eel could be infected with a parasite from poor pond biosecurity. Information about the types of parasites that infect swamp eels from natural caught and culture has never been reported before. The aims of these studies were to identify the endoparasite and calculate the prevalence and intensity of endoparasite in swamp eel from natural caught and cultivation. A total of one hundred and twenty swamp eel (37.7 +/- 2.5 cm height) collected from natural caught and pond culture in Banyuwangi. Two endoparasites helminth were infected to eels from natural caught and cultivation i.e Eustrongylides ignotus and Pingus sinensis. The higher prevalence and intensity of endoparasites helminth were found in swamp eel from natural caught than cultivation. Further studies were needed to molecular identified of endoparasite in swamp eel with a scanning electron microscope or 16rDNA.
