Molecular identification and prevalence of endoparasite worms in Silver pompano (Trachinotus blochii) in floating net cages of Mari-culture Center, Lampung

Abstract

Abstract Silver pompano (Trachinotus blochii) is one type of mari-culture that has high economic value and both national and international markets. The cultivation technique of silver pompano (T. blochii) used in floating net cages is inseparable from the common problems in every cultivation activity. one of these obstacles is the problem of infectious diseases, where is caused by disturbances this disease causes in fish metabolism by organisms such as parasites. The aim of this study was to identify the types of endoparasite worms based on molecular and the prevalence of endoparasite worms in silver pompano in floating net cages of Mari-culture Center, Lampung. It was done by taking 45 samples of fish with a length of 15-25 cm using a purposive sampling method. The observed internal organ of fish, then molecular identification, was carried out with conventional PCR and prevalence calculation. This study showed there was Camallanus carangid by DNA amplification fragments with a band of 972 bp and the prevalence value of 8.8%.
