The presence of large number of parasites is dangerous for a fish population, causes great loss of fisheries and fishing industry. Economic aspects of parasitic effects on fishes are mass mortality, weight losses, reduction in fish population and size of catches. Fish disease due to helminth parasites has an indirect and direct effect on the productivity of fish and on human health. The main aim of present work is to provide knowledge about the seasonal variation, intensity of parasitic infection, effect of length and sex on the infestation rate as well as parasitic communities found in this s...
The presence of large number of parasites is dangerous for a fish population, causes great loss of fisheries and fishing industry. Economic aspects of parasitic effects on fishes are mass mortality, weight losses, reduction in fish population and size of catches. Fish disease due to helminth parasites has an indirect and direct effect on the productivity of fish and on human health. The main aim of present work is to provide knowledge about the seasonal variation, intensity of parasitic infection, effect of length and sex on the infestation rate as well as parasitic communities found in this selected species. Overall our result does provide some support of epidemiological predictions. The larger the fish population, the more parasitic species occurs in different organs of the fish. The parasitic community was varied during the whole period of investigation. The differences in parasitic infestation were probably included the interaction of complex and often obscure ecological and physiological mechanism. This information is an important addition to the scientific literature and useful for parasitologists and fish pathologists.
