ABSTRACT
Research on ontogenetic dietary variation rainbow sardine relating to body size of fish with time was carried out from August 2009 to January 2010 in Kendari Bay, Southeast Sulawesi. This research aims to describe ecological role of rainbow sardine in Kendari Bay. Fish collection was done using experimental gillnets (with different mesh sizes ¾, 1, 1¼, and 1½ inch) and scope net (Ø 1 meter and mesh size 0.04 inch). A total of 136 individual fish were caught with range from 0.6 to 15.7 cm in length. Food analysis was determined by using Index of Preponderance. Result of the analysis indicates rainbow sardine is planktivora, which important diet is Bacillariophyceae. The male and females of fish did not have ontogenetic dietary (main food) shift and was not ontogenetic dietary shift relating to body size of fish. The diet of the fish every months was dominated by Bacillariophyceae.
Key words: body size, diet, Kendari Bay, ontogenetic, rainbow sardine, time.
