once a year

Three stations of Ogatsu Bay (St 1 - 3)

Field survey

We aim to survey a total amount of scallop production and the numbers of facility for scallop farming in Ogatsu Bay in order to calculate productivity of scallop and 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). We also plan to evaluate an availability of remote sensing data for estimation of chlorophyll a concentration in waters of Ogatsu Bay comparing with regular line observation and stationary measurement by observation buoy.
