| Fish is the master of aquatic life, which serves as hosts to a range of parasites that are taxonomically diverse and that exhibit a wide variety of life cycle strategies. Many of these parasites are passed directly between ultimate hosts whereas other needs a series of intermediate hosts. Parasites thrive primarily in a dynamic equilibrium with their host(s) and they are often overlooked in fish health assesments. The damage associated with the fish host is relative to the intensity of infection and severity of infection of parasite. Infection with parasite Diplostomulum metacercaria can lead to severe skin and other tissue pathology and change the haematological and biochemical parameters of Heteropneustes fossilis which may result in host mortality. |
