Low genetic diversity, local-scale structure, and distinct genetic integrity of Korean chum salmon () at the species range margin suggest a priority for conservation efforts.

Chum salmon () is an ecologically and economically important species widely distributed across the North Pacific Ocean. However, the population size of this fishery resource has declined globally. Identifying genetic integrity, diversity and structure, and phylogenetic relationships of wild populations of over an entire species' range is central for developing its effective conservation and management plans.

Population biology of the largemouth bass, Micropterus salmoides from Goe-San Lake, Korea.

The population biology of Micropterus salmoides were examined in Goe-san Lake from March 2010 to February 2011. The development of ovary and testis was separated into 5 stages by the criteria. The ratio of females to males increased with total length.

Salinity changes in the anadromous river pufferfish, Takifugu obscurus, mediate gene regulation.

This study aimed to better understand the hydromineral regulatory response of the anadromous river pufferfish, Takifugu obscurus, to salinity changes through real-time RT-PCR. After abrupt transfer from 30 or 5 psu to 5 or 30 psu, respectively, we analyzed the mRNA expression of Na⁺/K⁺ ATPase, prolactin receptor, and aquaporin from osmoregulatory organs of the river pufferfish such as gills, kidney, and intestine. Na⁺/K⁺ ATPase showed notable changes in the gills and kidney when salinity was increased.

Complete mitochondrial genome of the freshwater fish, Acanthorhodeus macropterus (Cypriniformes, Cyprinidae).

The complete mitochondrial genome was sequenced from the freshwater cyprinid fish, Acanthorhodeus macropterus. The genome sequence was 16,774 bp in size, and the gene order and contents were identical with another cyprinid fish, Acheilognathus yamatsutae. Of 13 protein-coding genes (PGCs), 3 genes (CO2, CO3, Cytb) had an incomplete stop codon.

Complete mitochondrial genome of the freshwater fish, Rhodeus suigensis (Cypriniformes, Cyprinidae).

Complete mitochondrial genome of the freshwater gudgeon, Pseudopungtungia nigra (Cypriniformes, Gobioninae).

The complete mitochondrial genome was sequenced from the freshwater fish, Pseudopungtungia nigra. The genome sequence was 16,605 bp in size, and the gene order and contents were identical with the cyprinid fish without any peculiar features. Of 13 protein-coding genes (PGCs), 3 genes (CO2, CO3 and Cytb) had an incomplete stop codon.

Complete mitochondrial genome of the striped bittering Acheilognathus yamatsutae (Cypriniformes; Cyprinidae).

The complete mitochondrial genome was sequenced from the striped bittering Acheilognathus yamatsutae. The genome sequence was 16,703 bp in size, and the gene order and contents were identical tot those of the congeneric species Acheilognathus signifer and other previously reported fish mitochondrial genomes. Of 13 protein-coding genes (PCGs), three genes (CO(2), CO(3), and Cytb) had incomplete stop codons.

Complete mitochondrial genome of the Korean bitterling Acheilognathus intermedia (Cypriniformes; Cyprinidae).

The complete mitochondrial genome was sequenced from the Korean bitterling Acheilognathus intermedia. The genome sequence was 16,610 bp in size, and the gene order and contents were identical with the congeneric Acheilognathus signifier and other previously reported fish mitochondrial genomes. Of 13 protein-coding genes (PCGs), three genes (CO2, CO3, and Cytochrome b) had incomplete stop codons.

Complete mitochondrial genome of the Korean bitterling Acheilognathus koreensis (Cypriniformes; Cyprinidae).

The complete mitochondrial genome was sequenced from the Korean bitterling Acheilognathus koreensis. The genome sequence was 16,563 bp in size, and the gene order and contents were identical with the same genera Acheilognathus signifier and other previously reported fish mitochondrial genomes. Of 13 protein-coding genes (PCGs), four genes (CO2, CO3, ND4, and Cytochrome b) had incomplete stop codons.

The complete mitochondrial genome of the javeline goby Acanthogobius hasta (Perciformes, Gobiidae) and phylogenetic considerations.

We isolated Acanthogobius hasta mitochondrial DNA by long-polymerase chain reaction (long-PCR) with conserved primers, and sequenced this mitogenome with primer walking. The resultant A. hasta mitochondrial DNA sequence was found to consist of 16,663 bp with a structural organization conserved relative to that of other fish.
