Abstract:
This study focused on a comparison of the parasite fauna in several different
economically important fish such as Etroplus suratenscis, Tachysurus spp., Glossogobius giuri, Ophiocephalus striatus, Oreochromis mossambicus and Ambassis commersoni at two locations within Batticaloa lagoon. Ergasilus parvitergum, Dermoergasilus amplectens, Caligus curtus, Lernaenicus sparatte, Procamellanous lonis and Acanthocephala sp., were the most common, and the occurrence of parasites among
the fin fishes of Batticaloa lagoon was wide spread. The parasite genera E. parvitergum
were the most prevalent on Etroplus suratensis whereas P. lonis and C. curtus was more
common on Glossogobius giuris, whilst L. sparatte was more common on Oreochromis
mossambicus; C. curtus and D. amplectens on Ambassis commersoni, and
Acanthocephala sp. and P. lonis were more common on Tachysurus.
