Paraulopidae and Paraulopus, a new family and genus of aulopiform fishes with revised relationships within the order
TLDR
Paraulopus clearly belongs in Aulopiformes owing to an enlarged uncinate process on the second epibranchial, the absence of a swimbladder, and fusion of the medial processes of the pelvic girdle, but the phylogenetic position of Paraulopus is defined by a cladistic analysis of 101 morphological characters, in 21 genera of Aulipiformes.
Genetic differences among three colour morphotypes of the black rockfish, Sebastes inermis, inferred from mtDNA and AFLP analyses
TLDR
The genetic differences among three colour morphotypes of the black rockish, Sebastes inermis, were determined from mitochondrial DNA and amplified fragment length polymorphisms (AFLP) analyses and indicated reproductive isolation among the morphotypes.
Molecular phylogenetic perspective on speciation in the genus Sebastes (Scorpaenidae) from the Northwest Pacific and the position of Sebastes within the subfamily Sebastinae
TLDR
The results clearly indicated separate origins for external morphology in Northeast and Northwest Pacific species and inferred the phylogenetic position of Sebastes was inferred among the subfamily Sebastinae, Helicolenus, Hozukius, Sebastes, and Sebastiscus, suggesting that HelicolenUS and HozUKius are more closely related to Sebastes than Sebastiscs.
The Sphyraena obtusata group (Perciformes: Sphyraenidae) with a description of a new species from southern Japan
TLDR
Three species of the S. obtusata group are described, characterized by having 2 gill rakers, and a key to the three species is provided.
Oncorhynchus kawamurae “Kunimasu,” a deepwater trout, discovered in Lake Saiko, 70 years after extinction in the original habitat, Lake Tazawa, Japan
TLDR
Oncorhynchus kawamurae (Osteichthyes: Salmonidae) (common name “Kunimasu”), a species endemic to Lake Tazawa, Akita Prefecture, Japan, was believed to have been extinct since 1940, was discovered in March and April 2010 and supported by microsatellite DNA data.
Molecular and morphological differences between two geographic populations of Salanx ariakensis (Salangidae) from Korea and Japan
TLDR
Both the principal component analysis (PCA) and canonical discriminant analysis (CDA) for morphometric characters, and the Kruskal–Wallis test for some meristic characters, showed that the two populations of S. ariakensis differed from each other, although morphological differences were consistent with the differences in mtDNA.
Taxonomic review of East Asian Pleuronichthys (Pleuronectiformes: Pleuronectidae), with description of a new species
A review of East Asian frog flounders, genus Pleuronichthys (family Pleuronectidae), recognized Pleuronichthys japonicus sp. nov. and P. cornutus (Temminck and Schlegel 1846). Pleuronichthys
Systematics of North Pacific sand lances of the genus Ammodytes based on molecular and morphological evidence, with the description of a new species from Japan
TLDR
The systematic status of North Pacific sand lances was assessed from mitochondrial DNA sequence data and morphological data to identify the number of species in the North Pacific Ocean and its fringing seas.
