Computational analysis of contamination in Kojima Lake using upwind-type finite element method

We have computed the phase of spreading contaminations in Kojima Lake by using the upwind-type finite element method. We have treated the two cases: the pollutant flows from the Sasagase river and from the Kurashiki River. We see that the upwind-type finite element method is effective in both cases, when the diffusion constant is quite small

Direction of Fisheries (SUISAN) Education from a Historical Perspective in Japan

Fishing, aquaculture, and food processing is collectively referred to as “SUISAN”, and the term was translated to “fisheries” in the Meiji period. Fisheries education in Japan was at its dawn. Fisheries education was necessary for improvement of local fisheries subsistence. Fisheries education was performed, centering on nurturing of mid-career engineers for deep-sea fishing after 1950s. However, when the Heisei period in the 1990s started, “participatory = citizen involvement type fisheries education” was promoted extensively. Future establishment of a Japanese version of Sea Grants is desired to promote citizen involvement in fisheries education with systematized involvement of universities, research institutions, aquaria, and local people
