The knowledge on the early development of fin fishes in Indian waters is incomplete and more information is needed on the early life history of a large number of species. The prospective values of the studies on the planktonic fish eggs and larvae have been widely recognised in recent years especially after standardisation of techniques for their rearing. Availability of extensive information on the biology of edible fishes is an essential prerequisite before planning for their proper management  and for rational exploitation of these resources. For aquaculture practices, information on early developmental stages of commercially important finfishes is essential. However ichthyoplankton survey conducted over a period of two years along Muthupettai waters, few embryonic and early stages of fin fishes were collected and then visibly were identified.
