Abstract
Mass mortalities of the pen shell Atrina SPP. occurred in the fishing grounds of Ariake Bay. We built up the hypothesis about a cause of mass mortality from long-term viewpoint (function of population) and short-term viewpoint (biological function). This study considered a cause of mass mortality from field survey, metabolism model of the pen shell and seasonal variation of glycogen contents. It was suggested that change of age structure and miniaturization lead to less sustainability of population. It turned out that the amount of food in the period from November to May is important for growth of pen shell. If glycogen content is not fully accumulated in this period, the physical strength of pen shell declines in summer or autumn, and it becomes easy to cause mortality.
