This study has been carried out from December, 2004 to July, 2005 in the sciaenid fishes along parangipettai coastal waters. The study aimed to establishing the magnitude of parasitization in different fish species as well as quantifying the relationship between the parasites and their fish hosts. There are 78 fresh sciaenid fishes belong's to 6 genus were examined for parasires of which 34.6% i.e. (27/78) showed the nematode prevalance. Of 10 species of parasites, such as Contracaecun aduncum, Cucullanus aunulatus, Camallanus truncates, Ascrophis filiformis, Rhaphidascaris acus, Porrocaecum sp., Hysterothylacium sp., Rhabdochona sp., Camallanides sp. and Paracanthocephalus gracilacanthus. The Camallanides sp. shows their presence in two species of Sciaenids namely Johnius soldado and Pseudosciaeno axillaries. The maximum number of infection (9) was recorded in by the parasite Rhabdochona sp. from the intestine of the host fishes Pseudosciaeno goldhanni. Among 8 Sciaenid fishes examined Otolithus argenteus, Kathala axillaries and Nibea maculata were free from parasitic infection in this study.
