Field survey
Overview
We will examine species composition and dynamics of larval and juvenile fishes in the surf zone and the seagrass bed in Okirai bay to estimate the impact of the 2011 disaster and recovery process from the disaster on the environment for fish reproduction in coastal area. We also examine dynamics of juvenile Japanese flounder in Otsuchi bay and Noda bay.
