In order to elucidate the biodiversity and origin of species diversity of freshwater fishes with high endemism in Far-Eastern Asia, genetic, morphological, ecological and ethological studies were carried out in Japan, Russia, Kazafstan and Taiwan, and as the results following valuable results were obtained :1) For the phylogenetic relationships among Lethenteron species in East Asia, it was elucidated that L.japonicum, L.kessleri and L.sp. N were monophyletic and L.sp.S derived from the common ancestral stock of the genera, Lethenteron, Lampetra and Entosphenus.2) It was found that crucian carps collected from the Ob River system in Kazafstan consisted of Carassius carassius and C.auratus, the latter including two groups at least ; one is native in Kazafstan and another is introduced presumably from China.3) East Asian ninespine sticklebacks (genus Pungitius) were composed of 3 major lineages (A. B and C). A linearized molecular clock tree based on AFLP data disclosed that the lineage … More A and (B+C) were diverged about 3.0 MYA, and lineages B and C were diverged 2.2 MYA.4) MtDNA sequence data disclosed that East Asian bagrid catfishes (Pseudobagrus-group) includes two major monophyletic lineages and that one of them is distributed in the whole range, including so-called Pseudobagrus, Peltobagrus and Coreobagrus, and the other consists of Chinese Leiocassis and some Pseudobagrus species.5) MtDNA sequence data disclosed that eastern Eurasian freshwater sculpins (genera Cottus and Trachidermus) include 5 major lineages A-E, lineage A consisting of T.fasciatus and C.kazika having a catadromous life-history, and lineages B-E consisting of the remaining Cottus species having amphidromous, lacustrine and fluvial life-histories.6) A comparative analysis of the relationship between genetic and phenotypic divergence in multiple sympatric pairs of threespine sticklebacks (the Pacific Ocean and Japan Sea forms of Gasterosteus aculeatus complex) disclosed that body size of fish may play an important role at the early stage of stickleback speciation and divergence of courtship repertories play an important role at the later stage.

为了阐明远东地区特有性较高的淡水鱼类的生物多样性和物种多样性的起源，在日本、俄罗斯、哈萨克斯坦和台湾等地开展了遗传、形态、生态和行为学研究，取得了以下有价值的成果：1）对于东亚Lethenteron物种的系统发育关系，阐明了L.japonicum、 L.kessleri 和 L.sp。 N为单系群，L.sp.S来源于Lethenteron属、Lampetra属和Entosphenus属的共同祖先种群。2)发现哈萨克斯坦鄂毕河水系采集的鲫鱼由Carassius carassius和C.auratus组成，后者至少包括两个类群；一种原产于哈萨克斯坦，另一种可能是从中国引进的。3) 东亚九刺棘鱼（Pungitius 属）由 3 个主要谱系组成（A、B 和 C）。基于AFLP数据的线性化分子钟树表明，谱系A和(B+C)的分歧约为3.0 MYA，谱系B和C的分歧为2.2 MYA。4) MtDNA序列数据表明，东亚鲢鱼(Pseudobagrus-group)包括两个主要的单系谱系，其中一个谱系分布在整个范围内，包括所谓的鲢鱼。 5）MtDNA序列数据显示，欧亚东部淡水杜父鱼（Cottus属和Trachidermus属）包括A-E 5个主要谱系，其中A谱系由具有降水生活史的T.fasciatus和C.kazika组成， 谱系 B-E 由具有两栖、湖泊和河流生活史的剩余 Cottus 物种组成。 6) 对多对同域三刺刺鱼（太平洋和日本海的棘刺鱼复合体）的遗传和表型分化之间关系的比较分析表明，鱼的体型可能在刺鱼物种形成的早期阶段发挥重要作用， 求偶库的分歧在后期发挥着重要作用。较少的
