Reconsideration of the Beginning Ayu Culture
Get PDFIn this paper, the author reconsidered when, where, and by whom breeding trials were begun in the latter half of the
Meiji period that resulted in the release of koayu (small sweetfish, Plecoglossus altirelis altivelis) seedlings into rivers. The
results are as follows．
There are four theories regarding the first breeding tests: the tests were conducted by Shirobei Fujino at Sodani-Fujino
f
ish farm in 1908, by Shiga prefectural fishery experiment station at the Sodani-Fujino fish farm in 1908, by Dr. Chiyomatsu
Ishikawa at the fishery experiment station’s Chinai hatchery in 1909, and by the fishery experiment station at the Chinai
hatchery in 1909. Of the four theories, the most plausible is that conducted by Shirobei Fujino in 1908 at the Sodani-Fujino
f
ish farm in Kaminiu, Samegai village; Current Maibara City, Shiga prefecture.
However, the Sodani-fujino fish farm was sold to Shirobei Fujino by Teijiro Nishikawa in 1905, and in “Keisho-chi
Samegai,” it is stated that the Nishikawa fish farm ayu cultivation. Dr. Chiyomatsu Ishikawa also confirmed in 1894 that
ayu were cultured at Nishikawa fish farm.
Therefore, the breeding trials linked to the koayu seedling release project date back to the time when Nishikawa fish
farm started ayu cultivation. Specifically, it can be pointed out that the period is prior to 1894 and up to 1885.departmental bulletin pape
Analyses on Long-term Interannual Variations in Area of the Tibetan High in July and August
Get PDFJapan has been experiencing extremely hot summers with maximum temperatures higher than 35℃ in the last few
years. Long-term interannual variations in area of the Tibetan High i.e. Tibetan anticyclone were investigated in July and
August from 1971 through 2023 using 10-day mean data. The result revealed that the Tibetan High is expanding at both
the 100hPa and the 200hPa levels in the past 53 years. The variations showed positive correlation between the 100hPa
and 200hPa levels at the 95％ significance level, suggesting that the differences in variations between the levels were
small. The maximum increase in area over the period was in mid-August for both isobars, with a maximum of 1.9％ for
the 200hPa level. Furthermore, when the coverage period was divided into the first and the second 30 years, the increas
ing rate was greater in the later period, indicating that in recent years the Tibetan High has continued to expand in area.departmental bulletin pape

Experimental Method of Triaxial Compression Tests for Soft Rocks: Application to Mudstone of the Kiwada Formation in the Kazusa Group
Get PDFAs for achieving carbon neutrality, various approaches are being attempted throughout the world. However, it is said
that current technologies such as renewable energy and nuclear power alone cannot reach zero emissions and that the
use of carbon removal technologies is essential to achieve carbon neutrality, and research is currently underway to realize
CCS (Carbon dioxide Capture and Storage). In selecting a suitable site for CCS, the use of underground space for storage
layers is being considered, and studies are underway to evaluate the potential of such space. The rocks considered to be
storage layers are often fragile (soft rocks) such as many pores, and it is necessary to conduct triaxial compression tests
to determine characteristics of failure to the soft rocks for long-term safety assessment. However, soft rocks are at the
boundary between rock and soil mechanics, it has not been studied extensively. In this study, we report on the experimen
tal procedures and fracture and deformation characteristics of isotropic consolidation tests and triaxial compression tests
(CD tests) on soft rocks (mudstones of the Kiwada Formation in the Kazusa Group).departmental bulletin pape
