Campbell 204 Participants 208 5 FOREWORD Lates calcarifer. or Barramundi as it is called in Australia and Sea Bass in Asia, is a fish that has a widespread distribution and a variety of roles in the fisheries of thc Indo­ Pacific region. For example, Thailand is perhaps the world leader in many aspects of the culture of L calcarifer. [n South Asia and Australia the main activity has been in the wildstock fishery. Due to the geographical distribution of the species, only recently has there been interest shown in the detailed study of the biology of L. calcarifer. Indeed the research priorities established as a result of the Workshop indicate the need for further biological research to assist the traditional culture of the species and to get a better understanding of its behaviour under natural conditions. The considerable intcrcst and country participation in this workshop reflects the importance of barramundi as a valuable natural resource for many countries in the Indo­ Pacific region. This workshop provided the first opportunity for scientists from the region to come together to share and exchange views on the various research priorities and production systems of this important species. The purpose of the workshop was to identify the scientists currently involved in Lates calcarifer research and to establish research priorities for the development of the spccies as a cultured and/or wild fish. ACIAR was pleased to assist in bringing the scicntists to Darwin and would like to thank the organising committee and to acknowledge the support given by Mr Nick Dondas, Minister of Ports and Fisheries, and members of his Department. The assistance of Peter Blake, Secretary of the Department, Wendy Flynn, Northern Territory Museum of Arts and Sciences, and Pam Griffin as Workshop Secretary, is gratefully acknowledged. Finally, I would like to thank Reg MacIntyre of ACIAR, for his role in the efficient editing and production of this publication, which has been appreciated by all the participants. J.R. McWilliam Director ACIAR 6 Summary of Discussion and Recommendations 7 Summary of Discussion and Recommendations i) General 1. The lack of an adequate knowledge base on all aspects of Lates calcarifer was identified as a major constraint to the management, development and protection of current and future wild and farmed fish resources. 2. There is a need for a central data basc which can be readily accessed and added to by scientists, planners and fishery managers. Such a data base could be placed in existing fishery institutions and research organisations, and could be supplemented by a Newsletter which could assist in adding to and accessing the data base. 3. There is a need to colleet and collate a bibliography of the available literature on L. calcarifer in order to appreciate the benefits of earlier research. Such a bibliography could form the first step in assembling a data base on L. calcarifer. 4. There is a need to

  • A Review of the Systematic Biology of Fossil and Living Bony-Tongue Fishes, Osteoglossomorpha (Actinopterygii: Teleostei)
    Neotropical Ichthyology, 16(3): e180031, 2018 Journal homepage: www.scielo.br/ni DOI: 10.1590/1982-0224-20180031 Published online: 11 October 2018 (ISSN 1982-0224) Copyright © 2018 Sociedade Brasileira de Ictiologia Printed: 30 September 2018 (ISSN 1679-6225) Review article A review of the systematic biology of fossil and living bony-tongue fishes, Osteoglossomorpha (Actinopterygii: Teleostei) Eric J. Hilton1 and Sébastien Lavoué2,3 The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutio- nary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these fishes, particularly with regard to the phylogenetic affinities of several fossil taxa, within Mormyridae, and the position of Pantodon. In this paper we review the state of knowledge for osteoglossomorph fishes. We first provide an overview of the diversity of Osteoglossomorpha, and then discuss studies of the phylogeny of Osteoglossomorpha from both morphological and molecular perspectives, as well as biogeographic analyses of the group. Finally, we offer our perspectives on future needs for research on the systematic biology of Osteoglossomorpha. Keywords: Biogeography, Osteoglossidae, Paleontology, Phylogeny, Taxonomy. Os peixes da Superordem Osteoglossomorpha têm sido foco de inúmeros estudos sobre a morfologia, sistemática e evo- lução, particularmente devido à sua posição basal dentre os peixes teleósteos.

  • Whole Genome Sequencing of the Asian Arowana (Scleropages Formosus) Provides Insights Into the Evolution of Ray-Finned Fishes

Accepted: September 28, 2015 Data deposition: This project has been deposited at DNA Data Bank of Japan/EMBL/GenBank under the accession JARO00000000. Abstract The Asian arowana (Scleropages formosus) is of commercial importance, conservation concern, and is a representative of one of the oldest lineages of ray-finned fish, the Osteoglossomorpha. To add to genomic knowledge of this species and the evolution of teleosts, the genome of a Malaysian specimen of arowana was sequenced. A draft genome is presented consisting of 42,110 scaffolds with a total size of 708 Mb (2.85% gaps) representing 93.95% of core eukaryotic genes. Using a k-mer-based method, a genome size of 900 Mb was also estimated. We present an update on the phylogenomics of fishes based on a total of 27 species (23 fish species and 4 tetrapods) using 177 orthologous proteins (71,360 amino acid sites), which supports established relationships except that arowana is placed as the sister lineage to all teleost clades (Bayesian posterior probability 1.00, bootstrap replicate 93%), that evolved after the teleost genome duplication event rather than the eels (Elopomorpha).

  • Seasonal Hydrology Shifts Production Sources Supporting Fishes in Rivers of the Lower Mekong Basin
    1342 ARTICLE Seasonal hydrology shifts production sources supporting fishes in rivers of the Lower Mekong Basin Chouly Ou and Kirk O. Winemiller Abstract: Seasonal hydrology is assumed to be an important reason why the Lower Mekong Basin supports highly productive and biodiverse inland fisheries. We used C and N stable isotope ratios of tissue samples to estimate primary production sources supporting fish biomass in the Mekong and three large tributaries in Cambodia. We used a Bayesian mixing model to estimate relative contributions of four alternative production sources — seston, benthic algae, riparian grasses, and riparian macro- phytes. There was little seasonal variation in isotopic signatures of riparian plants, but benthic algae and seston showed large seasonal shifts in carbon ratios. Seston and benthic algae were the most important production sources supporting fish biomass overall during the dry season, and riparian vegetation was the most important source during the wet season. Sources contributed differentially to biomass of trophic and habitat guilds, especially during the dry season. A dam on the upper Sesan River has changed hydrology, channel geomorphology, and other factors and, compared with the other three rivers, its fish biomass appears to derive from algae to a greater extent. Résumé : L’hydrologie saisonnière est présumée être une importante raison expliquant le fait que le bassin du cours inférieur du fleuve Mékong supporte des pêches continentales très productives et d’une grande biodiversité. Nous avons utilisé les rapports d’isotopes stables du C et du N d’échantillons de tissus pour estimer les sources de production primaire qui supportent la biomasse de poissons dans le Mékong et trois grands affluents au Cambodge.
