Abstract

A parasite is an organism that survives in or on another species, usually at the expense of its host. Among the fish-infecting parasites, three types of helminth parasites, namely, roundworms (nematodes), flatworms or flukes (trematodes), and tapeworms (cestodes), have the potential to cause zoonotic diseases. A large diversity of parasites that are taxonomically diverse and display a wide range of life cycle methods live on fish as hosts. While many of these parasites are transmitted straight from ultimate host to ultimate host, some must travel through several intermediate hosts before finding a host in (or on) whom they can reach sexual maturity. There are various methods for detecting nematode parasites in various fish species like internal transcribed spacers (ITS), mitochondrial COI, RFLP, AFLP etc. There are various Reports of nematode infection in fish and humans. Accurate identification of fish parasites is crucial to study the host-environment relations and formulate subsequent preventive strategies.
