Diseases of Marine Fishes and their role in the food-chain

Abstract

In their natural environments, fishes suffer from a variety of diseases. In India, very little consideration and less attention have been devoted on research to the possibility that man and fish may share disease• producing organisms in common or serve as vectors of each other's diseases. The need for much more research on fish as possible vectors of human infectious diseases is stressed here because of the increasing use of fish as human food, increasing contamination of the aquatic environment with human wastes and increasing direct contac t between man and the aquatic environment.
