Exotic populations of Acheilognatus tabira found in northern Mie Prefecture, and subjected to nucleotide sequencing of the mitochondrial DNA cytochrome b region, were determined to represent the Hokuriku (A. t. jordani) and Kinki-Sanyo (A. t. tabira) lineages. The first record of A. t. jordani from outside its native distribution area (Japan Sea side of western Honshu), it is likely to be a viable population due to the presence at the sampling site of the freshwater mussel Beringiana fukuharai (Unionidae, Cristariini), with which the former likely has a spawning relationship.

タナゴ亜科魚類(以下、タナゴ類)は純淡水魚であり、日本においては 3属 11種 8亜種からなるグループである。本グループの全種が環境省あるいは地方公共団体のレッドリストに掲載されている絶滅危惧種であると同時に、多くの種が国内外来種となっている。婚姻色が美しく多様であり愛玩動物や釣りの対象魚としても人気が高いことから、意図的と思われる放流が各地で確認されている。本論文では、在来タナゴ類の生息域内保全を目的として、国内外来種の分布情報や駆除事例、定着状況を文献から網羅的に整理した。その結果、 14種において移植情報が確認された。そのうち、イチモンジタナゴの記録が 19県と最も多かった。また、カネヒラ、ヤリタナゴ、シロヒレタビラ、アブラボテにおいても、 10都道県を超える確認情報が得られた。特に在来種の少ない東北地方において移植事例が多く見られた。その一方で、国内外来種の駆除については確認することができなかった。移入先における定着状況から、国内外来種の河川や湖沼における定着の可能性と在来種への生態的影響について考察した。また、国内外来種の移入要因を整理し、移入対策について検討した。

Non-native populations of Tanakia lanceolata were found in the Naruse River system, Miyagi Prefecture (Northern Honshu), Japan. Examination of nucleotide sequences of the mitochondrial DNA cytochrome b region indicated that the population was a genetic lineage of those naturally distributed in Western Honshu, Japan. In particular, a haplotype present in the Naruse River populations was consistent with one identified in populations in the Asahi and Kurashiki River systems, Okayama Prefecture.

Habitat use of Misgurnus anguillicaudatus was surveyed at Tanushimaru, Kurume City, Fukuoka Prefecture, Kyushu Island, Japan, at winter season. The study site was composed as traditional agricultural ditches in parts of the paddy field with some parts of concrete artificial type of the canals. The spatial distribution of M. anguillicaudatus in the study area was examined in 36 square frames (1 m × 1 m) located spaced along agricultural pathway for approximately 20 m. Relationships between presence of M. anguillicaudatus and several environmental factors was analyzed using the generalized linear model (GLM). Result of the GLM analysis showed that probability of the presence of M. anguillicaudatus mainly explained by water depth and the probability increased with increasing water depth.

During the 20th Century, most part of Japanese paddy fields were transformed to productive efficient allotments by the “Agricultural Land Improvement Projects”. However, the rich biodiversity, which was maintained in traditional paddy field forms with nature-near water supply systems, has led to a loss. In this research, the methodology of sustainable paddy field management which is aimed at balancing “efficient paddy field management” and “ecosystem conservation” was proposed by conducting the following three points. The focused site was Asami district in Matsuzaka city. First, the paddy fields were classified into 3 types according to the introduction of the agricultural land improvement project. Secondly, the differences of biodiversity and labor productivity by farmers among the three types were clarified. Thirdly, the future paddy field management scenarios were proposed and examined by considering a compromise point in this trade-off relationship between biodiversity and labor productivity.

Freshwater mussel (family Unionidae) utilization for oviposition by Sarcocheilichthys variegatus variegatus was investigated in a drainage ditch and the Harai River. Twenty five freshwater mussels in Pronodularia japanensis (4% of 616 individuals examined) in a drainage ditch connected to the Kushida River hosted S. v. variegatus eggs, compared with none of two other freshwater mussel species, Inversidens brandti and Unio douglasiae douglasiae. In the Harai River, eight freshwater mussels (3 I. brandti, 2 Obovalis omiensis, 1 Lanceolaria grayana and 1 Anodonta spp.) (2.7% of 290 individuals examined) hosted S. v. variegatus eggs, compared with none of P. japanensis and U. d. douglasiae. Among the available freshwater mussel species, U. d. douglasiae may be only one selected against for oviposition by S. v. variegates.
