| The feeding, clearance rate, and ingestion rate of Manila clam (Ruditapes philippinarum) were investigated with small group (10.8$pm$.58 mm in shell length) and large group (37.5$pm$3.8 mm in shell length) under combination in water temperature (24, 27, 33, $36^{circ}C$) With salinity (12, 15, 24, 27$ extperthousand$). The maximum feeding, clearance rate, and ingestion rate in small and large groups were $27^{circ}C$ and 27$ extperthousand$, respectively. While, The minimum feeding, clearance rate, and ingestion rate in both groups were $36^{circ}C$ and 12$ extperthousand$, respectively. There results were suggested that the feeding, clearance rate, and ingestion rate of Manila clam were significantly influenced by external factors such as water temperature and salinity. The reason for the mass mortality of Manila clam during the heavy rainfall in summer season can be explained by high temperature and low salinity. |
