| Outline of Final Research Achievements |
From 2014 to 2016, we carried out plankton surveys, during the surface current observation period by the Long Range Ocean Radar in the southwestern Japan Sea. The eggs and larvae of Engraulis japonicus were mainly distributed in the offshore region far from the Japanese coast. Typically, the second branch of the Tsushima Warm Current flows toward the east-northeast along the continental shelf break (about 200-m isobath). However, when the cold water in the Japan Sea intruded into the bottom layer of the continental shelf, southeastward flow was generated along the temperature front. It is considered that the southeastward flow advected the eggs and larvae from offshore to nearshore region.
