Period and Interval
2013/12/01 - 2013/12/31
once a year
Research Area
Two stations of Ogatsu Bay
Category
Field survey
Overview
The growth condition is calculated as a production per line based on the number of facility and annual production in the bay and compared to pre-quake level. In parallel with it the scallops cultured by ear hang method at two stations of Ogatsu Bay are also used for another estimation of growth condition. Shell size, weight of softbody and indicates of each organ is evaluated and compared to pre-quake level. The environmental capacity for scallop culture in Ogatsu Bay is considered by growth condition and food availability based on a primary production.
