A visit to the sampling site in China
Japan members, Prof. Katayama (The University of Tokyo) and Dr. Pu (Toyo University), visited the sampling site in China on May 21, 2019, with Dr. Liang (Tianjin Agriculture University). Fishing is banned between May 1 and Sep 1 in this sea area. Thus, oysters were collected from the coast instead of outer sea. Oysters collected were smaller than usual. Prof. Katayama guided the water concentration steps. He emphasized NaOH solution shall be prepared every time before use, since a drop of pH was observed in the stocking solutions.
