To elucidate the species diversity, taxonomic problems, syatematic zoogeography, morpho-ecological endemisms, reproductive systems, phylogenetic relationships and dispersal routes of coastal marine fishes and freshwater fishes in the Far East Russia, several expeditions were carried out in the Amur River, Lena River, Tumnin River and Peris Island during the three years from 1997 to 1999. Through the expeditions and laboratory works, following important findings were obtained. 1) The reproductive systems of some Cottid fishes belonging to the genus Pleurogrammus, Hemitripterus and Radulinopsis were found tobe non-copulating one by diving observations of their mating behavior. 2) An undescribed species of Zoarcidae was recorded from the coastal waters near Magadan, and another undescribed species of the genus Radulinopsis of Cottidae and the genus Eumesogrammus of Stichaeidae were also recorded from shallow sea areas of southern Premor'e. 3) The phylogenetic relationships among the species belonging to the genus Lethenteron, Tribolodon, Pungitius and Cottus were respectiveiy inferred from allozyme and mtDNA sequence data. 4) Within the genus Pungitius, two genetic clades (the Primor'e type and Skhalin-Okhotsk type) were newly detected from the freshwaters of Far East Russia. 5) The species of Lethenteron and Tribolodon are shown to have speciated around the Sea of Japan. 6) The two Cottid species, Trachidermus fasciatus and Cottus kazika , were shown to be monophyletic, suggesting that the Cottus species are not monophyletic but a paraphyletic group.

为了阐明物种多样性，分类问题，动物动物地理学，形态生态学，生殖系统，生殖系统，系统发育关系和沿海海洋鱼类和淡水鱼类的分散途径，俄罗斯远处的淡水鱼，在尤里斯河（Lina River），佩利斯河（Leena River），在尤里斯河中进行了几次探险，从埃纳河（Lina River）进行了1999年，从事了1999年的1997年。遵循重要的发现。 1）某些属于胸膜属，溶血膜和辐射素的棉鱼的生殖系统被发现通过潜水观察到它们的交配行为来使其不受欢迎。 2）从马加丹附近的沿海水域记录了一种未描述的Zoarcidae，以及哥布迪科的另一种未描述的种类，以及Stichaeidae的Eumesogramus属，也从南方南部的浅海地区记录了Stichaeidae属。 3）属于Lethenteron属，Tribolodon，Pungitius和Cottus的物种之间的系统发育关系是从同酶和mtDNA序列数据中推断出的。 4）在Pungitius属中，从远东俄罗斯的淡水中新发现了两个遗传进化枝（最初的类型和Skhalin-Okhotsk型）。 5）伦森特龙和tribolodon的种类已显示在日本海周围。 6）两种棉质物种是气管筋膜和库库·卡齐卡（Cottus Kazika），被证明是单一的，这表明这些棉质物种不是单一的，而是一个子植物群。
