Overview
We aim to survey a total amount of scallop production and the numbers of facility for scallop farming in Ogatsu Bay for calculation in order to compare with a pre-quake period. In addition, we plan to measure their shell size and weight of several organs and analyze for their growth condition between two different depth conditions. The environmental capacity for scallop culture in Ogatsu Bay can be evaluated by growth condition and food availability based on a primary production (i.e., monitoring of chlorophyll a concentration).
