Open AccessUsing a drifting GPS-Argos satellite buoy as a method for detecting acoustic-tagged fish offshore in an ancient lake
Telemetry methods that allow low-cost, offshore tracking are required for the effective conservation and sustainable use of migratory fish in large lakes with vast and deep offshore areas. Surface drifting buo...

A DNA mini-barcoding system for endangered unionid mussels in the Lake Biwa system in Japan
A mini-barcoding system was developed to help identify endangered unionid mussels in the Lake Biwa system in Japan. A single primer set was designed to amplify a ca. 140-bp barcode fragment based on the published...

Rhabdamia novaluna, a new species of cardinalfish (Perciformes: Apogonidae) from the western Pacific Ocean, with comments on the synonymy of Rhabdamia gracilis
The new cardinalfish Rhabdamia novaluna sp. nov. (Apogonidae) is described on the basis of 79 specimens collected from the western Pacific Ocean. The new species is most similar to the Indo-West Pacific species R...

A set of SNPs near or within STR regions useful for discriminating native Lake Biwa and introduced “Eurasian” strains of common carp
We present a set of nuclear DNA SNPs useful for discriminating native Lake Biwa and introduced “Eurasian” strains of common carp, and further, for detecting their hybridization. Such SNPs were searched around ...

Open AccessEvolutionary history of Otophysi (Teleostei), a major clade of the modern freshwater fishes: Pangaean origin and Mesozoic radiation
Freshwater harbors approximately 12,000 fish species accounting for 43% of the diversity of all modern fish. A single ancestral lineage evolved into about two-thirds of this enormous biodiversity (≈ 7900 spp.)...

Open AccessIndependent evolution of the specialized pharyngeal jaw apparatus in cichlid and labrid fishes
Fishes in the families Cichlidae and Labridae provide good probable examples of vertebrate adaptive radiations. Their spectacular trophic radiations have been widely assumed to be due to structural key innovat...

Gene Rearrangements and Evolution of tRNA Pseudogenes in the Mitochondrial Genome of the Parrotfish (Teleostei: Perciformes: Scaridae)
Genomic size of animal mitochondrial DNA is usually minimized over time. Thus, when regional duplications occur, they are followed by a rapid elimination of redundant material. In contrast to this general view...

Genetic differentiation between two color morphs of Apogon taeniophorus from southern Japan
The anterior half of the mitochondrial 16S rRNA gene (ca. 610 bp) was compared for two color morphs (spotted and lined types) of a dark-striped cardinalfish, previously identified as Apogon taeniophorus. Phylogen...
