Taxonomic and distributional information on each fish species found in arctic marine waters is reviewed, and a list of families and species with commentary on distributional records is presented. The list incorporates results from examination of museum collections of arctic marine fishes dating back to the 1830s. It also incorporates results from DNA barcoding, used to complement morphological characters in evaluating problematic taxa and to assist in identification of specimens collected in recent expeditions. Barcoding results are depicted in a neighbor-joining tree of 880 CO1 (cytochrome c oxidase 1 gene) sequences distributed among 165 species from the arctic region and adjacent waters, and discussed in the family reviews. Using our definition of the arctic region, we count 242 species with documented presence, if 12 species that likely are synonyms are excluded. The 242 species are distributed among 45 families. Six families in Cottoidei with 72 species and five in Zoarcoidei with 55 species account for more than half (52.5%) the species. This study produced CO1 sequences for 106 of the 242 species. Sequence variability in the barcode region permits discrimination of all species. The average sequence variation within species was 0.3% (range 0–3.5%), while the average genetic distance between congeners was 4.7% (range 3.7–13.3%). The CO1 sequences support taxonomic separation of some species, such as Osmerus dentex and O. mordax and Liparis bathyarcticus and L. gibbus; and synonymy of others, like Myoxocephalus verrucosus in M. scorpius and Gymnelus knipowitschi in G. hemifasciatus. They sometimes revealed the presence of additional species that were not entirely expected, such as an unidentified species of Ammodytes in the western Gulf of Alaska, most likely A. personatus; and an unidentified Icelus species of the I. spatula complex with populations in the western Gulf of Alaska and the northern Bering and Chukchi Seas which could be a new species or a species in synonymy. Reviewing distribution, we found that for 24 species the patterns assigned by authors understated historical presence in the arctic region, and for 12 species they overstated presence. For instance, Hippoglossoides robustus is counted as an arctic–boreal species rather than predominantly boreal, and Artediellus uncinatus as predominantly arctic rather than predominantly boreal. Species with arctic, predominantly arctic, or arctic–boreal distributions composed 41% of the 242 species in the region, and predominantly boreal, boreal, and widely distributed species composed 59%. For some continental shelf species, such as the primarily amphiboreal Eumesogrammus praecisus and Leptoclinus maculatus, distributions appear to reflect changes, including reentry into Arctic seas and reestablishment of continuous ranges, that zoogeographers believe have been going on since the end of land bridge and glacial times.

Based on a critical analysis of scientific publications for the last 200 years and on the collected specimens, a complete annotated list of both typical freshwater ichthyofauna of Sakhalin Island, with the inclusion of marine species that can be found in brackish coastal waters, is reported for the first time. The annotated list includes 226 species classified in three classes, 26 orders, 68 families, 29 subfamilies, and 148 genera. For 160 species, information is provided on collection samples deposited in various museums around the world, 36 of which are type specimens. For each species, conservation status (according to IUCN Red List of Threatened Species and the Red Book of the Sakhalin region), zoogeographic characteristics (distribution within Sakhalin Island and globally), abundance and commercial value are given. For a number of species, more detailed information on synonymy and nomenclature is provided. The study area is located in the western North Pacific and includes the entire coast of Sakhalin Island in the Sea of Okhotsk and the northern Sea of Japan, as well as the adjacent Sea of Okhotsk coast of northern Hokkaido, Japan.
The paper presents an overview of data based on the analysis of published information concerning the transoceanic migrations of lampreys (Petromyzontidae), sharks (Selachii), and actinopterygian fishes (Actinopterygii). A classification of transoceanic migrations, including eight various types depending on their characteristic features, is proposed. It is shown that transoceanic migrations are rather an exclusion than a norm, even in such good oceanic swimmers as tunas of g. Thunnus and marlins (Istiophoridae).
Synopsis
Evolutionary transitions between habitats have been catalysts for some of the most stunning examples of adaptive diversification, with novel niches and new resources providing ecological opportunity for such radiations. In aquatic animals, transitions from saltwater to freshwater habitats are rare, but occur often enough that in the Neotropics for example, marine-derived fishes contribute noticeably to regional ichthyofaunal diversity. Here, we investigate how morphology has evolved in a group of temperate fishes that contain a marine to freshwater transition: the sculpins (Percomorpha; Cottoidea). We devised a novel method for classifying dietary niche and relating functional aspects of prey to their predators. Coupled with functional measurements of the jaw apparatus in cottoids, we explored whether freshwater sculpins have fundamentally changed their niche after invading freshwater (niche lability) or if they retain a niche similar to their marine cousins (niche conservatism). Freshwater sculpins exhibit both phylogeographical and ecological signals of phylogenetic niche conservatism, meaning that regardless of habitat, sculpins fill similar niche roles in either saltwater or freshwater. Rather than competition guiding niche conservatism in freshwater cottoids, we argue that strong intrinsic constraints on morphological and ecological evolution are at play, contra to other studies of diversification in marine-derived freshwater fishes. However, several intertidal and subtidal sculpins as well as several pelagic freshwater species from Lake Baikal show remarkable departures from the typical sculpin bauplan. Our method of prey categorization provides an explicit, quantitative means of classifying dietary niche for macroevolutionary studies, rather than relying on somewhat arbitrary means used in previous literature.
Main concentrations of Gilbert’s Irish lord Hemilepidotus gilberti in the Russian waters of the Sea of Japan are registered off the coasts of South and Central Primorye and western Sakhalin. During the course of the year, the representatives of the species are found at the depths between 9 and 668 m at a water temperature of the near-bottom layer from –1.8 to +16.1°С. In the summer, they prefer the upper and middle zones of the shelf with a temperature between 1.5 and 3.0°С, while the fishes are found in the lower part of the shelf and upper zone of the continental slope with low positive temperatures in the winter. The juveniles live at smaller depths than adult individuals and at the largest seasonal temperature fluctuations. The fishes 3–37 cm in body length are registered in the catches, and the size group 18–26 cm prevails. The females are more abundant in the population, and they reach a larger body size than the males. Mass spawning occurs in August and September at the depth of 30–80 m. In the waters of Primorye, Gilbert’s Irish lord feeds on mainly decapods, polychaetes, and amphipods. From April to November, the daily ration of the juveniles and adult fishes is equal to 5.0 and 3.0% of body weight, respectively. Two maximums are observed in the feeding intensity of adult fishes: prespawning (July) and postspawning (November). The biomass of Gilbert’s Irish lord in the Russian waters of the Sea of Japan is estimated as 1500 t.
Executive Summary The following appendix of the Other species chapter summarizes the information currently known about sculpins (Families Cottidae, Hemitripteridae, Psychrolutidae, and Rhamphocottidae) in the Bering Sea/Aleutian Islands (BSAI) FMP. a) Summary of Major Changes 1. Total fishery catch data from 2006 and 2007 to date are presented for the sculpin complex. Data are broken down for sculpins from the following genera: Hemilepidotus, Myoxocephalus, Hemitripterus. Data for the rest of the sculpin species found in the BSAI are presented and reported as sculpin unidentified. 2. Information on total sculpin catch by target fishery and gear type for 2006. 3. Biomass estimates from the 2007 Bering Sea Shelf Survey are reported. 4. Authors present information for recommending the splitting of the BSAI sculpin complex into a Bering Sea Shelf assemblage, a Bering Sea Slope assemblage and an Aleutian Island assemblage. Therefore, we suggest separate ABCs and OFLs for each region. 5. Authors present new estimates of natural mortality for four species from the EBS shelf. New ABC/OFL recommendations based on new estimates of M are presented as an alternative to status quo calculations of ABC and OFL.

The feeding habits of two species of Irish lords, Hemilepidotus jordani, and H. gilberti, were analyzed. Decapods always dominate the diet of the two species. For H. jordani, Echiurus echiurus, Metridium, Tecticeps alascensis, young and eggs of fishes are also important as are Echiurus, polychaetes, amphipods, young fish, bivalves, and gastropods for H. gilberti. Seasonal, local, inter-annual, and age-related changes in the composition of the diet of the two species are examined.
