摘要

The natural foods of Penaeus indicus and Penaeus merguiensis at Tammalang Bay, Satun Province on the Andaman Coast of southern Thailand were found to consist of seven major items. The frequencies of occurrence were 56-89% bivalves, 44-83% gastropods, 16-71% amphipods, 4-29% polychaetes, 20-44% foraminiferans, 25-52% plant tissues, and 4-23% diatoms. Bivalves and gastropods dominated. Although the frequency of occurrence and numerical composition of these benthic organisms in the diet were similar between shrimp species, they varied depending on seasons. Bivalves and amphipods were more common in shrimp caught in the SW monsoon season (July) than in the NE monsoon season (December). More gastropods and polychaetes were found in December than in July. Based on the frequency of occurrence, foraminiferans, plant tissues, and diatoms seemed to be regularly consumed even though the numerical composition per individual was low.
