Abstract

• Stomach contents of the spadenose shark in Mon coastal water were studied by using the samples collected from the fish landing sites during October 2017 to September 2018. The present study revealed that the stomach contents of Scoliodon laticaudus were categorized by cephalopods (26.4%), fish (26.3%), shrimps (25.7%) and other crustaceans (21.6%) in the study period. According to the number and frequency occurrence, S. laticaudus is a cephalopods feeder and their feeding rate is not different in stations of the present study. The least food composition is other crustaceans for S. laticaudus. Seven species of fishes such as Rastrelliger brachysoma, Nemipterus japonicus, Harpodon nehereus, Johnius coitor, Polynemus paradiseus, Coilia dussumieri and Trichiurus lepturus, two species of cephalopods namely Sepia sp. and Loligo sp., three species of shrimps including Penaeus indicus, Acetes indicus and Metapenaeus brevicornsis in the stomach of this species were examined. In the stomach of S. laticaudus, 14 phytoplankton species and 16 zooplankton species were examined.
