Incidence of Clinostomum complanatum (Trematoda: Clinostomidae) in Trichogaster fasciata (Actinopterygii: Osphronemidae), the first report from Deepor Beel, Assam, India.

Fish constitute a major component of diet for the people of northeastern India and one of the main food items for most people in Assam. But fishes are facing serious risks due to parasitic infestations which deteriorate the food value and also leads to fish mortality. The present study aims to investigate the occurrence of helminth parasites in some selected fishes of the species Mystus tengara, Channa punctata, and Trichogaster fasciata collected from Deepor Beel, Guwahati, Assam. Trematode parasite species have been recorded from Trichogaster fasciata. The recovered trematode is Clinostomum complanatum belonging to the family Clinostomatidae. The present study incorporates the morphological, morphometric, and scanning electron microscopy studies of the prevailing parasite. This study is the first report on the occurrence of helminth parasites in the edible freshwater fishes collected from Deepor Beel. [ABSTRACT FROM AUTHOR]
