Helminth parasite spectrum of fishes in Meghalaya, Northeast India: a checklist.

Fish constitute a major component of diet for the people of Northeast India and they are extensively used as a protein-rich food for human consumption. The present studies incorporate the spectrum, composition and diversity of the parasitic species in freshwater fishes in Meghalaya, Northeast India, with a view to identifying the species recovered by morphological criteria based on light microscopy. The collection sites included sixteen foci from eleven districts of Meghalaya for parasites occurring in the common food fishes (Cypriniformes, Channiformes, Silurformes, Symbranchiformes and Anguilliformes). The helminth parasite spectrum recovered from the various piscine host species in the study area comprised of a total of 19 taxa: 2 monogenean, 8 trematode (4 adult and 4 metacercarial stages), 12 cestode (11 adult and a metacestode stage), 6 nematode (3 adult and 3 larval stages) and a single acanthocephalan species. A checklist of the parasite species with short remarks for each is provided herein.
