Here, we identified paralogous tlr22 genes in 13 teleost Duplication fishes by screening available fish genomic resources and using molecular cloning. We then conducted com- Expression pattern prehensive bioinformatics analyses and investigated spatiotemporal differences in the expression patterns of the Gymnocypris eckloni tlr22 genes in G. eckloni. The results indicated that more than three paralogous tlr22 genes were possessed by Teleost fishes some teleost fishes. Of these, tlr22c is specific to some subfamilies of the Cyprinidae (e.g., Barbinae, Cyprininae, Schizothoracinae, and Leuciscinae). Phylogenetic and syntenic analyses showed that the paralogous tlr22 genes originated from two single-gene duplication events. Molecular clock calculations dated the two gene duplication events at 49.5 and 39.3 MYA, which is before the common carp-specific genome duplication event and well after the fish-specific genome duplication. -

Symposium: Morphometrics Presentation: Oral Contact: Rahim Abdi, Khoramshahr University of Marine science and Technology Khoramshahr Khozestan 64199-43175 Iran E-Mail: [email protected] Abstract: In this study, the digestive system of 10 adult Otolithes ruber, were removed and the livers and pancreases were put in the formalin 10 % to be fixed. The routine procedures of preparation of tissues were followed and the paraffin blocks were cut at 6 microns, stained with H&E, PAS and Gomori studied under light microscope. The results of microscopic studies showed that liver as the greatest accessory organ surrounds the pancreatic tissue. Liver is a lobulated organ which surrounds the pancreas as an accessory gland among its lobules. Hepatic tissue of this fish is similar to many other osteichthyes. Hepatocytes include glycogen stores and fat vacuoles located around the hepatic sinusoids. Pancreas as a mixed gland microscopically was composed of lobules consisting of serous acini(exocrine portion) and langerhans islets (endocrine portion). However, pancreatic lobules are usually seen as two rows of acini among which there is a large blood vessel.

To assess the genetic diversity, structure, and population dynamics of Schizopygopsis pylzovi, we examined the changes in mitochondrial DNA sequences (the mtDNA control region and the Cyt b gene; 1835 bp) in 304 individuals from nine populations. The samples were segregated into 112 haplotypes, with high haplotype diversity and low nucleotide diversity. The haplotype diversity was highest in the Minhe (HS) range of Huangshui River and lowest in the Weiyuan (WY) range of Weihe River. Analysis of molecular variance showed that 69.64% of the total genetic variance was contributed by within-the-group variation and 30.36% was contributed by among-the-group variation. Pairwise FST revealed significant divergence between the populations. The FST Genetics and Molecular Research 15 (3): gmr.15038480 Y.N. Ma et al. -
Age Structure and Growth Characteristics of the Endemic Fish
Zoological Studies 50(1): 69-75 (2011) Age Structure and Growth Characteristics of the Endemic Fish Oxygymnocypris stewartii (Cypriniformes: Cyprinidae: Schizothoracinae) in the Yarlung Tsangpo River, Tibet Yin-Tao Jia1,2 and Yi-Feng Chen1,* 1Laboratory of Biological Invasion and Adaptive Evolution, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China 2Graduate School of Chinese Academy of Sciences, Beijing 100039, China (Accepted September 10, 2010) Yin-Tao Jia and Yi-Feng Chen (2011) Age structure and growth characteristics of the endemic fish Oxygymnocypris stewartii (Cypriniformes: Cyprinidae: Schizothoracinae) in the Yarlung Tsangpo River, Tibet. Zoological Studies 50(1): 69-75. The age structure and growth characteristics of Oxygymnocypris stewartii were studied using 430 specimens collected from the Yarlung Tsangpo River, Tibet. Our study on the length-frequency and age structure indicated that this population was suffering from unreasonable exploitation. The standard length (SL; mm)-body weight (W; g) relationship was W = 1.30 × 10-5 SL3.002. The SL (Lt)- and weight (Wt)-at-age relationships were described by von Bertalanffy growth functions -0.1069 (t - 0.5728) -0.1069 (t - 0.5728) 2.997 as follows: Lt = 877.4821[1 - e ] and Wt = 8805.1493[1 - e ] for females, and -0.1686(t - 0.6171) -0.1686(t - 0.6171) 3.098 Lt = 599.3939[1 - e ] and Wt = 3091.3496[1 - e ] for males. It was observed that O. stewartii grew faster during the 1st 3 yr than other schizothoracines inhabiting the same region, and then its growth became slower. Our study also indicated that (1) O. stewartii’s growth performance was relatively higher than those of other schizothoracines which inhabit the same region, and (2) its growth performance was relatively lower than those of other piscivore Cyprinidae fishes such as Culter alburnus Basilewsky which inhabit Wu and Cheng Lakes. -
Life History Traits of the Chinese Minnow Rhynchocypris
Liang et al. Zoological Studies 2014, 53:36 http://www.zoologicalstudies.com/content/53/1/36 RESEARCH Open Access Life history traits of the Chinese minnow Rhynchocypris oxycephalus in the upper branch of Yangtze River, China Yangyang Liang1,2, Xiaoyun Sui1,3*, Yifeng Chen1, Yintao Jia1 and Dekui He1 Abstract Background: Study of the life history traits of any species plays an essential role for understanding their relationship with the surrounding environment and scientific management. The Chinese minnow Rhynchocypris oxycephalus,an ecologically and economically important species which was widely distributed in East Asia, is currently diminishing. In the present study, we depicted the main life history traits of R. oxycephalus for the first time. Results: A total of 442 individuals were collected from April 2012 to March 2013, with total length (TL) ranging from 32.2 to 158.0 mm. The otolith (lapillus) was proved suitable for age determination. Moreover, the results from marginal increment ratio (MIR) analyses demonstrated its unusual growth pattern: two pairs of opaque and transparent bands were formed each year, which might provide some implications for the age determination of other species. The maximum age for females (4 years) was higher than for males (3 years), while 1- and 2-year-old individuals dominated the population. Both females and males reached maturity at 1 year, and the TL at first maturity was 78.8 mm for females and 60.3 mm for males. Obvious sexual dimorphism was observed as females growing faster and larger than males after maturity. As a multiple spawner, R. oxycephalus releases batches of eggs from April to August. -
And Adaptive Evolution in Their Mitochondrial Genomes
Genes Genet. Syst. (2014) 89, p. 187–191 Polyphyletic origins of schizothoracine fish (Cyprinidae, Osteichthyes) and adaptive evolution in their mitochondrial genomes Takahiro Yonezawa1,2, Masami Hasegawa1,2 and Yang Zhong1,3* 1School of Life Sciences, Fudan University, SongHu Rd. 2005, Shanghai 200438, China 2The Institute of Statistical Mathematics, Midori-cho 10-3, Tachikawa, Tokyo 190-8562, Japan 3Institute of Biodiversity Science and Geobiology, Tibet University, JiangSu Rd. 36, Lhasa, 850000, China (Received 25 July 2014, accepted 9 October 2014) The schizothoracine fish, also called snow trout, are members of the Cyprinidae, and are the most diversified teleost fish in the Qinghai-Tibetan Plateau (QTP). Clarifying the evolutionary history of the schizothoracine fish is therefore important for better understanding the biodiversity of the QTP. Although mor- phological and molecular phylogenetic studies have supported the monophyly of the Schizothoracinae, a recent molecular phylogenetic study based on the mito- chondrial genome questioned the monophyly of this taxon. However, the phylo- genetic analysis of that study was on the basis of only three schizothoracine species, and the support values were low. In this report, we inferred the phylo- genetic tree on the basis of mitochondrial genome data including 21 schizothora- cine species and five closely related species, and the polyphyletic origins of the Schizothoracinae were strongly supported. The tree further suggests that the Schizothoracinae consists of two clades, namely the “morphologically specialized clade” and the “morphologically primitive clade”, and that these two clades migrated independently of each other to the QTP and adapted to high altitude. We also detected in their mitochondrial genomes strong signals of posi- tive selection, which probably represent evidence of high-altitude adaptation. -

In this article, we investigated the transcriptomes of two ecotypes of scaleless carp (Gymnocypris przewalskii przewalskii and G. p. ganzihonensis) from the Tibetan Plateau. We used a transcriptome sequencing approach to screen approximately 250,000 expressed sequence tags (ESTs) from the gill and kidney tissues of twelve individuals from the Ganzi River and Lake Qinghai to understand how this freshwater fish has adapted to an ecological niche shift from saline to freshwater. We identified 9,429 loci in the gill transcriptome and 12,034 loci in the kidney transcriptome with significant differences in their expression, of which 242 protein-coding genes exhibited strong positive selection 2+ (Ka/Ks > 1). Many of the genes are involved in ion channel functions (e.g., Ca -binding proteins), immune responses (e.g., nephrosin) or cellular water absorption functions (e.g., aquaporins). These results have potentially broad importance in understanding shifts from saline to freshwater habitats. Furthermore, this study provides the first transcriptome of G. przewalskii, which will facilitate future ecological genomics studies and aid in the identification of genes underlying adaptation and incipient ecological speciation. The causes of speciation have long been one of the central questions in evolutionary biology1–6. -
