Report on the infection of Pallisentis sp. from wild Croacking Gourami, Trichopsis sp

Abstract

The croaking gourami, Trichopsis sp. is a species of dwarf freshwater tangle fish of the gourami family and commonly found in South East Asia. They are native and distributed worldwide via the aquarium trade. This species is intrinsic and very popular for the ornamental fish industry especially in Malaysia, Thailand, Singapore and Indonesia. The purpose of this study is to identify the general morphology of Acanthocephala parasites, Palisentis sp. in wild Trichopsis sp. Five wild fish sample (N=5) with weight (0.79±0.18g) and length (4.18±0.69cm) were collected and dissected for endoparasites examination. There were five Acanthocephala found from this observation. Morphological characteristic showed that the species of this parasite is Pallisentis sp. and found in intestine. The infected fish did not show any signs such as abnormal behaviour or emaciation. This data is useful for disease prevention especially in the ornamental fish industry.
