Introduction to Grant Projects

Professor Tsuyoshi Imai, Department of Sustainable Environmental Engineering, Faculty of Engineering, Yamaguchi University

Development of new methods for introducing gas to promote gas-liquid contact in aquaculture ponds used in developing countries

Research grant

Project Description

On the premise that the innovative liquid-film type oxygen supply device (which is inexpensive and easy to transport and maintain) that the applicant has developed is suitable for use in freshwater aquaculture ponds in Thailand, a field study will be conducted in Thailand using the facilities at a Thai university where the device will be assessed through practical experiments to clarify the effectiveness of its introduction.
