| Abstract;The feeding habits of juveniles and adults of two sympatric sillaginid fishes, Sillago sihama and S. aeolus, were examined on the basis of 892 (127 juveniles and 765 adults) and 734 (159 and 575) specimens, respectively, collected from the sandy bottom at Sikao Bay, Trang Province, Thailand, from May 2003 to April 2004. The diets of juveniles (<130mm in standard length) of both species changed progressively with increasing body size, with a shift from capturing small zooplankton, such as calanoid copepods, to larger benthic prey, such as polychaetes, shrimps, and crabs. The latter three items were also the most important prey of adults of the two species, together constituting >70% of stomach contents by volume. Pronounced seasonal changes in adult diet were not detected in either fish species. In addition, considerable overlaps of juvenile and adult diets between the two coexisting Sillago species were found during the study period, indicating that there may be little or no competition between them at Sikao Bay.
