Abstract
Trichogaster fasciata (Kholshe fish) is going to disappear day by day. Helminth parasites are the primary causes of diseases in this fish. Three infectious Helminth parasites are found that are Trematode, Clinostomum complanatum; Nematode, Camallanus sp.; and Acanthocephala, Pallisentis ophiocephali. Trematode is the most infectious and dangerous among the three. All invade in the specific sites, i.e. body cavity, stomach, rectum and intestine. Female Kholshe fishes are more susceptible than the males. Males are more resistant to the Helminth parasites. Abundance of diseases is highest in the summer season, followed by rainy and winter. It is due to the high temperature, pH and scarcity of dissolved oxygen in the water of the cultured fisheries. Severe Helminth infections in Kholshe fishes are one of the leading causes for their extinction in freshwater of the nature.
