Redescription of (Nichols, 1926) with the description of a new species of the genus (Cypriniformes, Gobionidae) from southern China.

Although (Nichols, 1926) has been treated valid since it was described, its morphology remains vague, especially when comparing it with another similar species, (Yao & Yang, 1977). In this study, the types of both species were examined and also compared with several lots of specimens from a wide geographical range: there is no significant difference in morphology between them. Additionally, molecular evidence supported by mitochondrial gene sequence also showed low genetic distance in between.

Genetic diversity and structure of the Chinese lake gudgeon ().

Mitochondrial DNA cytochrome and d-loop sequences (2,137 bp) in 65 specimens of from five populations were identified as two lineages (I and II). The pairwise genetic distance between lineages I and II was 1.94%.

New insights on geographical/ecological populations within Coilia nasus (Clupeiformes: Engraulidae) based on mitochondrial DNA and microsatellites.

The Coilia nasus is an important fish species, which is of commercial values in China. In order to manage the fisheries resources and the development of sustainable fishing strategies to protect this species, 11 microsatellite loci polymorphisms and mtDNA COI sequences were used to examine the genetic diversity of C. nasus in Japan and China.

Spatial genetic structure of the cyprinid fish Onychostoma lepturum on Hainan Island.

Population genetic structure of Onychostoma lepturum on Hainan Island was investigated based on mitochondrial CR + cyt b region in 63 specimens collected from four populations. Population analyses indicated significant genetic structure (F = 0.749) and displayed a significant relationship between phylogeny and geography (N = 0.

The population history of Garra orientalis (Teleostei: Cyprinidae) using mitochondrial DNA and microsatellite data with approximate Bayesian computation.

Background: The South China landmass has been characterized by a complex geological history, including mountain lifting, climate changes, and river capture/reversal events. To determine how this complexity has influenced the landmass's phylogeography, our study examined the phylogeography of Garra orientalis, a cyprinid widely distributed in South China, using sequences from the mitochondrial DNA control region and cytochrome b gene (1887 bp) and polymorphisms of thirteen microsatellite loci.

Results: In total, 157 specimens were collected from eight populations.

The complete mitogenome of the oriental sucking barb, Garra orientalis (Cypriniformes, Cyprinidae): repetitive sequences in the control region.

The oriental sucking barb, Garra orientalis, is a small to moderate-sized freshwater fish. In this study, the complete mitochondrial genome of G. oriental was successfully sequenced for the first time with total length of 17,288 bp.

[Review on taxonomical studies of Chinese inland-water fish].

We reviewed the taxonomy and systematics research history of freshwater fish in China based on 1 236 taxonomic literature records on Chinese freshwater fish. The research was divided into five research periods according to specific historical events: (1) period by foreign scholars, (2) period with Chinese scholars, (3) period during World War II and Civil War, (4) recovery period and (5) period of rapid development. There were representative studies and innovations in all periods.

The complete mitochondrial genome sequence of Sarcocheilichthys nigripinnis (Cypriniformes, Cyprinidae).

We determined the complete mitochondrial genome (mitogenome) sequence of Sarcocheilichthys nigripinnis by using long polymerase chain reaction method. The total length of S. nigripinnis mitogenome is 16,680 bp, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a noncoding control region.

Complete mitochondrial genome of Osteochilus salsburyi (Cypriniformes, Cyprinidae).

Osteochilus salsburyi (Cypriniformes, Cyprinidae) is a small-sized fish of significant economic value. In this paper, the complete mitogenome sequence of O. salsburyi was first determined.

Complete mitochondrial genome of the endangered roughskin sculpin Trachidermus fasciatus (Scorpaeniformes, Cottidae).

In this study, the complete mitochondrial genome of the endangered roughskin sculpin, Trachidermus fasciatus, was first determined. The mitogenome (16,536 bp) consisted of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. Except for the eight tRNA and ND6 genes, all other mitochondrial genes were encoded on the heavy strand.

Comparative evolution of S7 Intron 1 and ribosomal internal transcribed spacer in Coilia nasus (Clupeiformes: Engraulidae).

Coilia nasus is widely distributed in the Yangtze River, the coastal waters of China, Korea and the Ariake Sound of Japan. Several ecotypes exist and this provides a useful model for the study of comparative diversity between molecular markers. Here we analyze and compare the nucleotide sequences between single-copy ribosomal protein S7 gene intron 1 (rpS7) and multiple-copy ribosomal internal transcribed spacer 1 (ITS1) in this species to compare the phylogenetic signal of the two nuclear genes.

[Analysis of genetic diversity in wild populations of Trachidermus fasciatus by RAPD and the transformation of two SCAR markers].

Firstly, RAPD was conducted to analyze genetic diversity of Trachidermus fasciatus in the Fuchun River population (FR), Yellow River population (YR), Luan River population (LR), and Yalu River population (YL), with 32 polymorphic 10-bp random primers selected from 294 ones. Thirty wild individuals were detected in each population. The results indicated that the genetic diversity of T .

Phylogeographical analysis on Squalidus argentatus recapitulates historical landscapes and drainage evolution on the island of Taiwan and mainland China.

Phylogeographical analyses on Squalidus argentatus samples from thirteen localities within mainland China and Taiwan were conducted for biogeographic studies, as their dispersal strictly depends on geological evolution of the landmasses. A total of 95 haplotypes were genotyped for mtDNA cyt b gene in 160 specimens from nine river systems. Relatively high levels of haplotype diversity (h = 0.

Complete mitochondrial genome of the mudskipper Boleophthalmus pectinirostris (Perciformes, Gobiidae): repetitive sequences in the control region.

The mudskipper, Boleophthalmus pectinirostris (Perciformes, Gobiidae), is an amphibious gobioid fish. In this paper, the complete mitochondrial genome of B. pectinirostris was firstly determined.

Polymorphic microsatellite loci isolated from the Squalidus argentatus using PCR-Based Isolation of Microsatellite Arrays (PIMA).

Squalidus argentatus (Sauvage and Dabry de Thiersant 1874) is a small-sized freshwater fish which is distributed in Mainland China, Hainan Island and Taiwan. The populations of S. argentatus have dropped sharply probably due to overharvesting and water pollution recently.

Behavioral migration diversity of the Yangtze River Japanese Eel, Anguilla japonica, based on otolith Sr/Ca ratios.

The Yangtze River estuary is the main production area of Anguilla japonica in China, as well as the only existing fishery area for adult eels. Japanese eels are distributed in the main rivers and many tributaries from the Yangtze River estuary to the upper Jinsha River, which extend to nearly 3 000 km. However, their migration behaviors remain relatively unknown.

A new record species of Chaetodontidae, Heniochus diphreutes, was found by comparative analysis of the morphological characteristics in a taxonomic revision of the family Chaetodontidae in China. It was distinguished from its relative species H. acuminatus by a combination of the following: Dorsal fin usually with 12 spines (vs.

Morphological changes of silver and bighead carp in the Yangtze River over the past 50 years.

Multivariate analysis was adopted to analyze 30 morphometrical characteristics of 121 one-year-old juvenile silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis) bred during the 1950s ("the former population") and 2008 ("the current population") and collected from the middle reach of the Yangtze River. The average discriminant accuracies of the former and current silver and bighead carp population were 94.2% and 98.

Ontogenetic changes in meristic measurements of silver carp and bighead carp.

The study analyzed 30 exterior meristic characters for 255 silver and bighead carp samples of 1- to 5-year-old collected from the National Primary Breeding Farm at Laojianghe Lake at the Middle Reach of the Yangtze River. Multivariate analysis was performed. In silver carp, the Euclidean distance was the greatest between the 1-year-old group and other age groups.
