This is an open-access article distributed under the terms of the Creative Commons Attribution ShareAlike (CC BY-SA) 4.0 License. ABSTRACT. 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.

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.

  • Phylogeny of the Specialized Schizothoracine Fishes (Teleostei: Cypriniformes: Cyprinidae)
    Zoological Studies 40(2): 147-157 (2001) Phylogeny of the Specialized Schizothoracine Fishes (Teleostei: Cypriniformes: Cyprinidae) Zi-Ming Chen1,2 and Yi-Feng Chen1,* 1Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan, Hubei 430072, China 2Kunming Institute of Zoology, Chinese Academy of Sciences, Kunming, Yunnan 650223, China (Accepted January 30, 2001) Zi-Ming Chen and Yi-Feng Chen (2001) Phylogeny of the specialized schizothoracine fishes (Teleostei: Cypriniformes: Cyprinidae). Zoological Studies 40(2): 147-157. To elucidate phylogenetic relationships within the specialized schizothoracine fishes, we used 41 variable osteological and external characters among this groups, three species of Schizothorax, and 1 fossil species. When the 3 species of Schizothorax were desig- nated as an outgroup and all 41 characters were set as unordered with equal weighting, the data matrix yielded a single most-parsimonious tree with a tree length of 71 steps, a consistency index of 0.6761, and a retention index of 0.7416. Meanwhile, a bootstrap test was conducted to verify the reliability of the results. The matrix was also analyzed for different conditions: all characters were ordered and the fossil species was added as an outgroup. The phylogenetic analyses presented herein support the following hypotheses. 1) All species of the specialized schizo-thoracines fishes form a monophyletic group. 2) Monophyly of the genus Ptychobarbus is not supported by the bootstrap test or when these characters are ordered. 3) The genus Gymnodiptychus forms a monophyletic group. 4) All species of Ptychobarbus and Gymnodiptychus form a monophyletic group with Diptychus as its sister group. Key words: Cyprinidae, Specialized schizothoracine fishes, Character analysis, Phylogenetic relationships, Tibetan Plateau.

  • 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.

  • On the Fish Fauna of Ladakh with Notes on Zoogeography
    R.c. IO~/. SurV. India, 87(2) : 131-149, 1990 ON THE FISH FAUNA OF LADAKH WITH NOTES ON ZOOGEOGRAPHY RAJTILAK Zoological Survey ofIndia, Dehra Dun. INTRODUCTION Steindachner (1966) was the rust worker to report on the fishes of Ladakh, collected by Dr. Stoliczka and described three new genera of Schizothoracinae viz. Schizopygopsis from Henle, Diptychus from Leh and Ptychobarbus from Henle together with three new species of the genus Noemachailus viz. N. tenuicauda from Henle, N. stoliczkae from Tso Morari, Rupshu and N. microps fro~ Leh. Subsequently, these species of fishes were included in the Catalogue of the fi~,hes of the Bitish Museum by Guenther (1868) who described Noemacheilus ladacensis from head waters of the Indus river in Ladakh. Day (1876-1877) described Exostoma stoliczkae from Leh and Noemacheilus gracilis from head waters of the Indus river; he also recorded Schizothorax richardsonii (= Oreinus sinuatus), Schizothoraichthys esocinus, Ptycnobarbus conirostris, Sehizopygopsis stoliezkae, Diptyehus maeulatus and Noemacheilus stoliczkae form Ladakh. Zugmayer (1909, 1910) deseribed two. species, Schizothorox ladaeensis Zugmayer and S. montanus Zugmayer from Indus river near . Leh but no reference to these species appear to have been made .by subsequent workers on the Ladakh fishes. It is not possible to study and check up the exact systematic position of the fishes described by Zugmayer (1909, 1910) des to lack of material of these species and, therefore, these taxa are being included her~ in the fauna of Ladakh. As and when material of these species is available, the systematic status of thes~ species will be decided in future; these species are very closely related to Schizo thorax ric~dsonii (Gray).

P. Basu Printing Works, Calcutta-6 EDITOR'S PREFACE Publication of Pauna of India is one of the major tasks of Zoological Survey of India. This department is a premier insti­ tute on Systematic Zoology in India and has on its staff experts on almost all groups of animals. The extensive systematic works on different groups of animals conducted by these experts are published in a large number of research publications which are scattered and not easily available to general zoologists and research workers in Universities and Colleges. In order to present these important studies in a consolidated form, various experts on djffe­ rent groups of animals are assigned the job of writing up Fauna of India on respective groups of animals. In this line, the Fauna of India on fishes is being written by renowned ichthyologists ; a few volumes are already published while some are in the process of publication. The present volume on Schizothoracinae is one of this series. Schizothoracinae are a group of cyprinid fishes inhabiting fast flowing streams mostly in high altitude areas. Dr. Raj TiIak has undertaken the task of updating the information on this group of high altitude hill-stream fishes, collating available informations together with those of his own.

Abstract Sympatric speciation remains a central focus of evolutionary biology. Although some evidence shows speciation occurring in this way, little is known about the gene expression evolution and the characteristics of population genetics as species diverge. Two closely related Gymnocypris fish (Gymnocypris chui and Gymnocypris scleracanthus), which come from a small glacier lake in the Tibetan Plateau, Lake Langcuo, exist a possible incipient sympatric adaptive ecological speciation.

    Electronic Journal of Ichthyology April, 2008 1: 31-42 SPECIES RICHNESS, DISTRIBUTION PATTERN AND HABITAT USE OF FISHES IN THE TRANS-HIMALAYAS, INDIA Sivakumar, K. Wildlife Institute of India, P.O. Box 18, Chandrabani, Dehradun 248 001, India [email protected] Abstract The cold desert of Ladakh is a catchment of the Indus river, which contains three major sub- basins: the Indus, Shyok and Zanskar of the higher Himalayas. A survey on lotic water fishes was conducted between April and September 2001 and covered a wide altitude ranging from 2750 m to 5386 m above mean sea level. In total, 41 streams and six rivers were sampled. A total of 32 species of fishes were recorded in the streams and rivers of Ladakh landscape: of which, five were exotic species primarily confined to some sites in the Indus subcatchment. Species richness in the Indus subcatchment was higher (29 species) than other two catch- ments. The Zanskar (10 species) had the fewest species. The current distribution pattern of fish in the Ladakh indicates that this landscape is a transient zone between the palearctic and oriental realms. Fishes in the Trans-himalayas highly used the streams which have more algal growth on the substratum. Snowtrout Diptychus maculates, which occur in abundant in the Ladakh waters would be useful for fisheries. Keywords: fish, snowtrout, Ladakh, Trans-Himalayas, stream fishes Introduction confined to few localities that too focus on The study of fish and fisheries has had a commercial fishes. long and distinguished history in India (Hora Habitat changes in Himalayan waters have 1951), but relatively little attention has been been reviewed (Shrestha 1990) and have paid to fish conservation here.
