An annotated list of cartilaginous fishes (Chondrichthyes: Elasmobranchii, Holocephali) of the coastal waters of Sakhalin Island and the adjacent southern part of the Sea of Okhotsk

An annotated list of cartilaginous fish (Chondrichthyes: Elasmobranchii, Holocephali) is given for the first time in the 200-year history of studying the ichthyofauna of Sakhalin Island and adjacent waters of the southern part of the Sea of Okhotsk (including the coast of Hokkaido Island) and the northern Sea of Japan. The list includes 43 species in two classes, eight orders, 16 families, and 25 genera. Information on nature conservation status, English and Latin names, depths of habitat, and distribution within the coastal waters of Sakhalin are presented. For a number of species caught off the coast of Sakhalin and in the adjacent waters, information is provided on collection specimens confirming their presence in the region under study. For a number of species of the Rajiformes order (Arctoraja parmifera, A. smirnovi, A. simoterus), the modern ranges and taxonomic status are being refined in the light of new data. The taxonomic status of the so-called “disputed” taxa is discussed as well as the validity of the species considered in the Bathyraja matsubarai complex. Based on the study of the collections, Arctoraja simoterus, previously unknown in the waters of Russia, as well as Myliobatis tobijei, caught in the Bering Sea, has been discovered, which significantly expands the range of this species to the north

Annotated list of ichthyofauna of inland and coastal waters of Sakhalin Island. 5. Families Cyclopteridae-Liparidae

The fifth part of the review represents the last part of the annotated list of fish species found in the marine (within a 200-mile zone), brackish, and fresh waters of Sakhalin: 84 species from one order Perciformes, one suborder Cottoidei, two families Cyclopteridae and Liparidae, and 13 genera. The review also represents general ecological characteristics of the ichthyofauna of Sakhalin, as well as a final essay

Annotated list of ichthyofauna of inland and coastal waters of Sakhalin Island. 2. Families Osmeridae-Scombropidae

The second part of the report represents the annotated list of fish species found in the marine (within a 200-mile zone), brackish, and fresh waters of Sakhalin: 139 species from 22 orders, 54 families, and 105 genera

Annotated list of ichthyofauna of inland and coastal waters of Sakhalin Island. 1. Families Petromyzontidae-Salmonidae

A complete annotated list of marine, brackish-water, and freshwater ichthyofauna of Sakhalin Island and the adjacent southern part of the Sea of Okhotsk is provided for the first time in the entire history of the study of the fish population. It is based on a critical analysis of the literature data for the last 200 years, collection materials, and the results of our own long-term studies. The list includes 600 species in 4 classes, 44 orders, 17 suborders, 129 families, 50 subfamilies, and 312 genera. It presents both English and Latin (scientific) names, information on the ranges in the World Ocean and distribution within Sakhalin waters, and data on the conservation status, commercial importance, and abundance. For a number of species, the list also provides information on collection specimens, confirming their presence within the studied water area. For all species, the current ranges and taxonomic status are specified according to the new data, if any. The so-called controversial taxa are discussed. The first part provides brief information about the history of the study of the Sakhalin ichthyofauna, the geographical and oceanological characteristics of the study area, as well as the first 118 species of the annotated list belonging to 79 genera, 42 families and 20 orders in 4 classes

Ichthyofauna of the fresh and brackish waters of Russia and adjacent areas: annotated list with taxonomic comments. 1. Families Petromyzontidae–Pristigasteridae

A complete annotated list of fresh and brackish waters ichthyofauna of the Russian Federation and adjacent areas, based on a critical analysis of scientific publications of the last 200 years, and on the data of the authors' research, is the aim of this study. The taxonomic composition of the freshwater and brackish water fish fauna of Russia remains insufficiently studied. This may result incorrect data on the true number of fish species of this category, not only for the waters of Russia, but also in the modern system of the world ichthyofauna as a whole, and also does not give a complete idea of the range, degree of endemism, abundance, conservation status, commercial value, and others important aspects. Until the present study, according to various sources, the Russian freshwater and brackish water ichthyofauna was estimated to amount from 351 to 486 species, respectively. However, based on our ongoing research, these numbers are too low and need to be revised. The total species number in all categories should include at least 800 species also including the introduced non-native species, as well as species not yet recorded from Russian waters, but suggested to be found in the future. In this first part of our updated checklist, we provide a basic historical review of ichthyological research in Russia, together with the first 77 species belonging to three classes (Petromyzonti, Elasmobranchii and Actinopteri), ten orders (Petromyzontiformes, Lamniformes, Carcharhiniformes, Squaliformes, Rajiformes, Myliobatiformes, Acipenseriformes, Elopiformes, Anguilliformes and Clupeiformes), nineteen families (Petromyzontidae, Alopiidae, Lamnidae, Triakidae, Carcharhinidae, Sphyrnidae, Somniosidae, Squalidae, Rajidae, Arhynchobatidae, Dasyatidae, Acipenseridae, Polyodontidae, Megalopidae, Anguillidae, Muraenesocidae, Clupeidae, Engraulidae and Pristigasteridae) and 38 genera. For each species, the following details are presented: scientific and English common names, taxonomic position with comments and synonyms (if necessary), conservation status, world distribution, zoogeographic characteristics, distribution in Russian waters and adjacent areas, abundance, and commercial value
