This manuscript summarizes the results of our paper, which has been awarded by the Japanese Society of Fisheries Engineering, on the process of the mortality of Japanese littleneck clam (Ruditapes philippinarum) due to large winter waves. The major finding of the paper is negative influence of the frequency in the clam exposure to the seabed surface and the burrowing rate on glycogen content and condition factor as indicators of energy store. We also suggest other factors affecting the abundance of clam resources such as warmer water temperature in winter and discuss methodology to stabilize the clam resources in future.
