Abstract
Aquaculture augments fish production, thereby generating more income and livelihood for the people involved. However, fish disease hinders the smooth ongoing development of the aquaculture industry. They harm the health of fish. The maintenance of a large number of fish crowded together in a small area provides an environment conducive to the development and spread of infectious diseases. In this cramped and crowded environment, fish are more prone to diseases and infections. Fish diseases can be broadly categorized into two types, namely infectious disease, caused by a pathogenic organism such as bacteria, virus, parasite, protozoa, etc., and noninfectious disease caused due to physical, chemical, biological, and handling or procedural changes to the fish. The diseases can be sporadic, epizootic, epizootic, and enzootic. To confirm the infections caused by a pathogenic organism in a host, Koch’s Postulates are used. Diseased Anabas testudineus fish were collected fish farm, near Guwahati, Assam. Then bacteria were isolated aseptically from the lesion on the body surface, followed by bacterial culture and reinfection on healthy fish. The symptoms, the causative agents, pattern of occurrence, etc were observed. The study tries to focus on healthy aquaculture practices and also helps in improvement in fish production.
