We examined the 77 phylogenetic relationships of the Cyprininae based on extensive taxon, geographical, and 78 genomic sampling of the taxa, using both mitochondrial and nuclear genes to address the 79 phylogenetic challenges posed by polyploidy. Four datasets were analyzed in this study: 80 two mitochondrial gene datasets (465 and 791 taxa, 5604bp), a mitogenome dataset (85 81 taxa, 14,771bp), and a cloned nuclear RAG1 dataset (97 taxa, 1497 bp). Based on 82 resulting trees, the subfamily Cyprininae was subdivided into 11 tribes: Probarbini (new; 83 Probarbus + Catlocarpio), Labeonini Bleeker, 1859 (Labeo & allies), Torini Karaman, 84 1971 (Tor, Labeobarbus & allies), Smiliogastrini Bleeker, 1863 (Puntius, Enteromius & 85 allies), Poropuntiini (Poropuntius & allies), Cyprinini Rafinesque, 1815 (Cyprinus & 86 allies), Acrossocheilini (new; Acrossocheilus & allies), Spinibarbini (new; Spinibarbus), 87 Schizothoracini McClelland, 1842 (Schizothorax & allies), Schizopygopsini Mirza, 1991 88 (Schizopygopsis & allies), and Barbini Bleeker, 1859 (Barbus & allies). Phylogenetic 89 relationships within each tribe were discussed. Two or three distinct RAG1 lineages were 90 identified for each of the following tribes Torini, Cyprinini, Spinibarbini, and Barbini, 91 indicating their hybrid origin. The hexaploid African Labeobarbus & allies and Western 92 Asian Capoeta are likely derived from two independent hybridization events between 93 their respective maternal tetraploid ancestors and Cyprinion. 94 95 Keywords: Biogeography; Cyprinidae; Evolution; Hexaploids; Taxonomy; Tetraploids 96 97 98 99 100 101 102 103 104 3 105 1. Introduction 106 Within vertebrates, phylogenetic resolution of the largest group, Actinopterygii or 107 ray-finned fishes, lags behind other taxa, due to the large number of species and the 108 difficulties obtaining and identifying specimens. Another challenge in actinopterygian 109 phylogeny is the evolution of genome duplications producing polyploids. Genome 110 duplications have occurred multiple times in actinopterygian evolution but are 111 particularly prevalent in Cypriniformes, the largest clade of freshwater fishes (Amores, et 112 al. 1998; Leggatt & Iwama, 2003; Taylor et al. 2003). Within Cypriniformes, the 113 Cyprininae contains more than 1300 freshwater species in over 120 genera, accounting 114 for nearly 4% of bony fish diversity (Eschmeyer, 2015). Most species of this subfamily 115 inhabit waters of southern Eurasia and Africa. Some are well known, such as the common 116 carp (Cyprinus carpio) and Goldfish (Carassius auratus). The Cyprininae contains 117 around 400 closely related polyploid species (Arai, 2011; Froese & Pauly, 2015), more 118 than other polyploid fish lineages, such as Acipenseriformes, Salmoniformes, and 119 Catostomidae (all <250 species; Eschmeyer, 2015). Over 30 genera in this subfamily 120 consist only of polyploid species (Leggatt & Iwama, 2003; Arai, 2011). Most polyploids 121 in this subfamily are either tetraploids (2n = ca.100) or hexaploids (2n = ca.150). The 122 species Ptychobarbus dipogon has an amazingly large number of chromosomes (2n = 123 446, Cui et al. 1991; 2n= 424-432, Wu et al. 1999). 124 The classification of the subfamily Cyprininae is still under discussion as various 125 numbers of formal or informal groups have been recognized within it (Tables 1&S1). 126 Many molecular studies have been conducted on the phylogenetic relationships of the 127 Cyprininae; however, most were limited by restricted taxon or character sampling or 128 limited geographical sampling. Most importantly, these studies either did not use nuclear 129 genes or used, but ignored the issue of paralogy associated with polyploid taxa. If a 130 nuclear gene has only one copy in diploids, it is expected to have two copies in 131 tetraploids, three copies in hexaploids, and four copies in octoploids. In polyploids, 132 especially allopolyploids, the different nuclear gene copies could be quite divergent and 133 belong to distinct clades in a gene tree (e.g. Evans et al. 2005; Saitoh et al. 2010). Direct 134 amplification of these nuclear genes with PCR (polymerase chain reaction) without using 135 specially designed paralog-specific primers will likely result in a mixture of gene copies. 4 136 If nuclear copies are not sorted appropriately, homology cannot be confidently 137 established, potentially misleading phylogenetic studies. In the present study, extensive 138 DNA cloning was performed and multiple alleles were used in phylogeny reconstruction 139 of all major diploid and polyploid lineages of the subfamily Cyprininae. These data and 140 molecular phylogenies inferred from mitochondrial genes made it possible for us to 141 explore the phylogenetic relationships and subdivisions of this subfamily as well as the 142 evolution of polyploidy. 143 The major objectives of this study are: 1) to investigate the phylogenetic 144 relationships and subdivisions of the subfamily Cyprininae based on the largest taxon, 145 geographical, and genomic sampling to date; and 2) to propose a classification for this 146 group. The evolution of polyploid lineages; the distribution of some morphological 147 characters important in classification; and biogeography of some taxa will be discussed. 148 149 2. Materials and Methods 150 2.1 Taxon sampling and datasets 151 Four datasets were analyzed in this study: 1) a mitochondrial gene dataset with 465 152 taxa (465-taxon mt dataset); 2) an expanded mitochondrial gene dataset with 791 taxa 153 (791-taxon mt dataset); 3) a mitochondrial genome dataset with 85 taxa (mitogenome 154 dataset); and 4) a cloned RAG1 dataset with 97 taxa (RAG1 dataset). 155 In the 465-taxon mt dataset, most taxa (97.4%) were represented by sequences from 156 five mitochondrial genes: cytochrome oxidase subunit I (COI), Cytochrome b (Cyt b), 157 16S ribosomal RNA (16S rRNA), NADH dehydrogenase subunit 4 (ND4), and NADH 158 dehydrogenase subunit 5 (ND5); remaining taxa (2.6%) were represented by sequences 159 from at least three genes. This dataset has good representation for major lineages

Yet, much has Conservation changed in the two seemingly disparate practices over the last two decades, motivating an updated evaluation of Aquaculture the scientific evidence for how aquaculture currently impacts conservation, as well as prospects for further Ecosystem services alignment and research. Here we present a new perspective on conservation aquaculture, which we redefine as Recovery “the use of human cultivation of an aquatic organism for the planned management and protection of a natural Restoration resource.” Looking across scales of conservation aquaculture that include single species to ecosystem level benefits (and limitations), we highlight ways aquaculture has historically, and is currently being integrated into conservation (e.g., habitat restoration of oyster beds) and areas that could be improved for the protection of critical species and habitats (e.g., aquarium trade of coral reef species). With a more strategic focus, there appears to be notable conservation aquaculture potential via the cultivation of species for harvest that could provide wild harvest alleviation through replacement or supplement – particularly for over-exploited species – and/or ecosystem services, such as improved water quality and reduction in greenhouse gas emissions.

  • Freshwater Fish Survey of Homadola-Nakiyadeniya Estates, Sri Lanka
    FRESHWATER FISH SURVEY OF HOMADOLA-NAKIYADENIYA ESTATES, SRI LANKA. Prepared by Hiranya Sudasinghe BSc. (Hons) Zoology, M.Phil. reading (University of Peradeniya) INTRODUCTION The diversity of freshwater fishes in Sri Lanka is remarkably high, with a total of 93 indigenous fishes being recorded from inland waters, out of which 53 are considered to be endemic (MOE, 2012; Batuwita et al., 2013). Out of these, 21 are listed as Critically Endangered, 19 as Endangered and five as Vulnerable in the National Red List (MOE, 2012). In addition, several new species of freshwater fishes have been discovered in the recent past which have not yet been evaluated for Red Listing (Batuwita et al., 2017; Sudasinghe 2017; Sudasinghe & Meegaskumbura, 2016; Sudasinghe et al., 2016). Out of the 22 families that represent the Sri Lankan freshwater ichthyofauna, the family Cyprinidae dominates, representing about 50% of the species, followed by the families Gobiidae, Channidae and Bagridae, which represent seven, five and four species, respectively. The remainder of the other families are each represented in Sri Lanka by three species or less. Four major ichthyological zones, viz. Southwestern zone, Mahaweli zone, Dry zone and the Transition zone were identified by Senanayake and Moyle (1982) based on the distribution and the endemism of the fish. The Southwestern zone shows the greatest diversity, followed by the Mahaweli zone, with the least diversity observed in the Dry zone. About 60% of the freshwater fishes occur both in the dry and the wet zones of the island while the rest are more or less restricted to the wet zone. Of the endemic fishes, more than 60% are restricted to the wet zone of the island while about 30% occur in both the dry and the wet zones.

We used mitochondrial history to examine diversity of the Hamid Reza Ghanavi, Department of algae- scraping cyprinid Capoeta in Iran, applying the species- delimiting approaches Biology, Lund University, Lund, Sweden. Email: [email protected] General Mixed Yule- Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examined temporal divergence patterns of Capoeta. The monophyly of the genus and the existence of three previously described main clades (Mesopotamian, Anatolian- Iranian, and Aralo- Caspian) were confirmed. However, the phylogeny proposed novel taxonomic findings within Capoeta. Results of GMYC, bPTP, and phylogenetic analyses were similar and suggested that species diversity in Iran is currently underestimated. At least four can- didate species, Capoeta sp4, Capoeta sp5, Capoeta sp6, and Capoeta sp7, are awaiting description. Capoeta capoeta comprises a species complex with distinct genetic line- ages. The divergence times of the three main Capoeta clades are estimated to have occurred around 15.6–12.4 Mya, consistent with a Mio- Pleistocene origin of the di- versity of Capoeta in Iran. The changes in Caspian Sea levels associated with climate fluctuations and geomorphological events such as the uplift of the Zagros and Alborz Mountains may account for the complex speciation patterns in Capoeta in Iran.

  • Impact of Fishing with Tephrosia Candida (Fabaceae) on Diversity
    Impact of fishing with Tephrosia candida (Fabaceae) on diversity and abundance of fish in the streams at the boundary of Sinharaja Man and Biosphere Forest Reserve, Sri Lanka Udaya Priyantha Kankanamge Epa & Chamari Ruvandika Waniga Chinthamanie Mohotti Department of Zoology & Environmental Management, Faculty of Science, University of Kelaniya, Kelaniya 11600, Sri Lanka; [email protected], [email protected] Received 07-V-2015. Corrected 04-III-2016. Accepted 31-III-2016. Abstract: Local communities in some Asian, African and American countries, use plant toxins in fish poisoning for fishing activities; however, the effects of this practice on the particular wild fish assemblages is unknown. This study was conducted with the aim to investigate the effects of fish poisoning using Tephrosia candida, on freshwater fish diversity and abundance in streams at the boundary of the World Natural Heritage site, Sinharaja Forest Reserve, Sri Lanka. A total of seven field trips were undertaken on a bimonthly basis, from May 2013 to June 2014. We surveyed five streams with similar environmental and climatological conditions at the boundary of Sinharaja forest. We selected three streams with active fish poisoning practices as treatments, and two streams with no fish poisoning as controls. Physico-chemical parameters and flow rate of water in selected streams were also measured at bimonthly intervals. Fish were sampled by electrofishing and nets in three randomly selected confined locations (6 x 2 m stretch) along every stream. Fish species were identified, their abundances were recorded, and Shannon-Weiner diversity index was calculated for each stream. Streams were clustered based on the Bray-Curtis similarity matrix for fish composition and abundance.

The parasitic fauna included two myzozoans, one choanozoan, seven ciliophorans, 24 myxozoans, eight trematodes, 34 monogeneans, 12 cestodes, 11 nematodes, five acanthocephalans, two annelids and nine crustaceans. The infection with some trematodes and nematodes occurred with larval stages, while the remaining infections were either with trophozoites or adult parasites. Among the inspected fishes, Cyprinion macrostomum was infected with the highest number of parasite species (29 parasite species), followed by Carasobarbus luteus (26 species) and Arabibarbus grypus (22 species) while six fish species (Alburnus caeruleus, A. sellal, Barbus lacerta, Cyprinion kais, Hemigrammocapoeta elegans and Mastacembelus mastacembelus) were infected with only one parasite species each. The myxozoan Myxobolus oviformis was the commonest parasite species as it was reported from 10 fish species, followed by both the myxozoan M. pfeifferi and the trematode Ascocotyle coleostoma which were reported from eight fish host species each and then by both the cestode Schyzocotyle acheilognathi and the nematode Contracaecum sp.

And this was suggested as one of the earliest records for fossil cyprinids. Unfortunately, this specimen is poorly preserved and reveals no more morphological information than its serrated last unbranched dorsal and anal fin rays. Recently, some new specimens were unearthed from the same locality, where C. maomingensis was discovered. In addition to the serrated dorsal and anal fin rays, these new materials also show that the pattern and shape of their pharyngeal teeth obviously differ from that of Cyprinus but resemble that of Procypris. However, its number of the branched dorsal fin rays and number of vertebrae are much less than that in Procypris.

As such it plays a crucial role in local livelihood, food Molecular Genetics Laboratory, security and occupies a prominent place in the diet of the hilly populace with traditionally identified Directorate of Coldwater pharmacological benefits in treating smallpox, stomachache, urinary and digestive problems. The Fisheries Research, Bhimtal, kingfish reportedly withstands a wide range of temperature and exhibits herbivores, but opportunistic Uttarakhand, India feeding behavior. In recent times, it has been identified as a potential species for diversification in hill aquaculture. On the other hand, C. Semiplotum population is declining in its natural habitat due to Prabhati Kumari Sahoo ICAR-Central Institute of overexploitation and related anthropogenic pressures. Presently, it has been classified as vulnerable in the Freshwater Aquaculture, IUCN red list of threatened species. In scientific terms, key questions regarding its breeding biology, Bhubaneswar, Odisha, India culture aspects, and conservation measures remain unanswered. Considering all the above, we have summarized the outcome of various studies carried on this vulnerable species regarding its taxonomic Rupak Nath ambiguity, ecology, behavior, growth, reproduction, nutrition, pharmacological benefit, fisheries, and St.
