Cypriniformes of Borneo (Actinopterygii, Otophysi): an Extraordinary Fauna for Integrated Studies on Diversity, Systematics, Evolution, Ecology, and Conservation
Zootaxa 3586: 359–376 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA Copyright © 2012 · Magnolia Press Article ISSN 1175-5334 (online edition) urn:lsid:zoobank.org:pub:7A06704C-8DE5-4B9F-9F4B-42F7C6C9B32F Cypriniformes of Borneo (Actinopterygii, Otophysi): An Extraordinary Fauna for Integrated Studies on Diversity, Systematics, Evolution, Ecology, and Conservation ZOHRAH H. SULAIMAN1 & R.L MAYDEN2 1Biological Science Programme, Faculty of Science, Universiti Brunei Darussalam, Tungku BE1410, Brunei Darussalam; E-mail:[email protected] 2Department of Biology, 3507 Laclede Ave, Saint Louis University, St Louis, Missouri 63103, USA; E-mail:[email protected] Abstract Borneo Island is governed by the countries of Brunei Darussalam, Malaysia (Sabah and Sarawak) and Indonesia (Kalimantan) and is part of Sundaland. These countries have a high diversity of freshwater fishes, especially described and undescribed species of Cypriniformes; together these species and other flora and fauna represent an extraordinary opportunity for worldwide collaboration to investigate the biodiversity, conservation, management and evolution of Borneo’s wildlife. Much of the fauna and flora of Borneo is under significant threat, warranting an immediate and swift international collaboration to rapidly inventory, describe, and conserve the diversity. The Sunda drainage appears to have been an important evolutionary centre for many fish groups, including cypriniforms (Cyprinidae, Balitoridae and Gyrinocheilidae); however, Northwestern Borneo (Brunei, Sabah and Sarawak) is not connected to Sundaland, and this disjunction likely explains the non-homogeneity of Bornean ichthyofauna. A previous study confirmed that northern Borneo, eastern Borneo and Sarawak shared a similar ichthyofauna, findings that support the general hypothesis for freshwater connections at one time between western Borneo and central Sumatra, and south Borneo and Java island. -

The mitotic chromosome preparation was prepared by directly from kidney cells of five male and five female specimens. Conventional and Ag-NOR staining techniques were applied to stain the chromosomes. The results shown that the diploid chromosome number of H. wyckii was 2n=62 and the fundamental numbers (NF) of both sexes were 110. The karyotype consists of 14 large metacentric, 14 large submetacentric, 8 large acrocentric, 8 medium metacentric, 4 medium submetacentric, 6 medium telocentric, and 8 small telocentric chromosomes. No strange size chromosomes related to sex were observed. In addition, the interstitial nucleolar organizer regions (NORs) were clearly observed at the long arm of the chromosome pair No. -
Geometric Morphometrics and Phylogeny of the Catfish Genus Mystus Scopoli (Siluriformes:Bagridae) and North American Cyprinids (Cypriniformes)
Geometric Morphometrics and Phylogeny of the Catfish genus Mystus Scopoli (Siluriformes:Bagridae) and North American Cyprinids (Cypriniformes) by Shobnom Ferdous A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama December 14, 2013 Copyright 2013 by Shobnom Ferdous Approved by Jonathan W. Armbruster, Department of Biological Sciences, Auburn University & Committee Chair Craig Guyer, Department of Biological Sciences, Auburn University Michael C. Wooten, Department of Biological Sciences, Auburn University Lawrence M. Page, Curator of Fishes, Florida Museum of Natural History Abstract Understanding the evolution of organismal form is a primary concern of comparative biology, and inferring the phylogenetic history of shape change is, therefore, a central concern. Shape is one of the most important and easily measured elements of phenotype, and shape is the result of the interaction of many, if not most, genes. The evolution of morphological traits may be tightly linked to the phylogeny of the group. Thus, it is important to test the phylogenetic dependence of traits to study the relationship between traits and phylogeny. My dissertation research has focused on the study of body shape evolution using geometric morphometrics and the ability of geometric morphometrics to infer or inform phylogeny. For this I have studied shape change in Mystus (Siluriformes: Bagridae) and North American cyprinids. Mystus Scopoli 1771 is a diverse catfish group within Bagridae with small- to medium-sized fishes. Out of the 44 nominal species worldwide, only 30 are considered to be part of Mystus. Mystus is distributed in Turkey, Syria, Iraq, Iran, Afghanistan, Pakistan, India, Nepal, Sri Lanka, Bangladesh, Myanmar, Thailand, Malay Peninsula, Vietnam, Sumatra, Java and Borneo. -
Analysis of Growth and Nutritional Values of Three Generations of Asian Redtail Catfish (Hemibagrus Nemurus) Irin I
Analysis of growth and nutritional values of three generations of Asian redtail catfish (Hemibagrus nemurus) Irin I. Kusmini, Kurniawan Kurniawan, Fera P. Putri, Deni Radona, Anang H. Kristanto, Rudhy Gustiano Research Institute for Freshwater Aquaculture and Fisheries Extension, Bogor, Indonesia. Corresponding author: F. P. Putri, [email protected] Abstract. The Asian redtail catfish (Hemibagrus nemurus) is a popular aquaculture fish species that contains essential nutrients for health. This research was carried out to evaluate the growth and nutritional values of the domesticated fish from 3 generations. 3 generation brood-stocks were artificially spawned using GnRH-analog hormone injection to produce fish larvae. The larvae were reared in the rectangular tank to reach the fingerling phase over two months. The fingerlings (with a length of 7.67±0.06 cm and a weight of 7.12±0.23 g) were cultured in semi-permanent ponds (160 cm x 80 cm x 100 cm), at a density of 100 fish per pond over 180 days and fed twice a day using commercial diets. The growth performances (weight gain, specific growth rate) of the first (G1), second (G2), and third generations (G3) showed no significant differences. The coefficient of variation (CV) of G2 was 26.61±11.39% and it was higher than that of G1 (18.26±0.65%) and G3 (14.71±2.45%). The factor condition (K) ranged from 0.81±0.02 to 1.02±0.5. The length-weight relationship showed that the growth pattern was allometric negative (<3), indicating a faster increase in length than in weight. -

^ Journal of Biogeography, 27, I 153-l I67 , Maps of Pleistocene sea levels in Southeast Asia: shorelines, river systems and time durations Harold K. Voris Field Museum of Natural History, Chicago, Illinois, USA Abstract Aim Glaciation and deglaciation and the accompanying lowering and rising of sealevels during the late Pleistoceneare known to have greatly affected land massconfigurations in SoutheastAsia. The objective of this report is to provide a seriesof mapsthat estimatethe areasof exposed land in the Indo-Australian region during periods of the Pleistocenewhen sealevels were below present day levels. Location The maps presentedhere cover tropical SoutheastAsia and Austral-Asia. The east-westcoverage extends 8000 km from Australia to Sri Lanka. The north-south coverage extends 5000 km from Taiwan to Australia. Methods Present-day bathymetric depth contours were used to estimate past shore lines and the locations of the major drowned river systemsof the Sunda and Sahul shelves. The timing of sea level changesassociated with glaciation over the past 250,000 years was taken from multiple sourcesthat, in some cases,account for tectonic uplift and sub- sidenceduring the period in question. Results This report provides a seriesof maps that estimate the areasof exposed land in the Indo-Australian region during periods of 17,000, 150,000 and 250,000 years before present. The ancient shorelinesare basedon present day depth contours of 10, 20, 30, 40,50,75, 100 and 120 m. On the maps depicting shorelinesat 75,100 and 120 m below present levels the major Pleistoceneriver systemsof the Sunda and Sahul shelves are depicted. Estimatesof the number of major sealevel fluctuation events and the duration of time that sealevels were at or below the illustrated level are provided. -

Proceedings of the Nature Reserves Survey Seminar. w re 49(2) (1997) Gardens' Bulletin Singapore 49 (1997) 245- 265. The Diversity and Conservation Status of Fishes in the Nature Reserves of Singapore PETER K.L. NG AND KELVIN K.P. LIM Raffles Museum of Biodiversity Research Department of Biological Sciences National University of Singapore Kent Ridge, Singapore 119260 Abstract An update on the taxonomy and conservation status of the 61 indigenous species of freshwater fis hes now known from Singapore is provided. Of these, 26 species (43%) are extinct. Of the 35 extant species, 33 are known in the Nature Reserves and 21 appear to be restricted there. Of the 52 introduced species of fish in Singapore, 17 are present in the Nature Reserves. The conservation status of native fishes in the Nature Reserves is assessed and the survival of hi ghly threatened species discussed. The significance of the Nature Reserves for freshwater fi sh conservation is highlighted. Introduction : be ascertained. The freshwater fish fauna of Singapore is among the best studied in the region and has been the subject of many publications (Alfred, 1961, 1966; Johnson, 1973; Munro, 1990; Lim & P.K.L. Ng, 1990; P.K.L. Ng & Lim, 1996). In the first major synopsis of the Singapore ichthyofauna, Alfred (1966) listed a total of 73 native and introduced species from Singapore of which 42 were still extant. Alfred (1968) subsequently listed 35 native species as extant and believed 19 were extinct. It was 22 years before the next appraisal was made by Lim & P.K.L. Ng (1990) in their guide to the freshwater fishes of Singapore. -

Through its stomach content analysis, the fish has been found to be omnivorous and euryphagous, with only a few qualitative differences in the diet. Feeding rate was found to vary in relation to monsoon caused environmental changes during the course of a year. Among the wide variety of prey consumed, juvenile fishes (39.88%) formed an important dietary component. The next major food group was insects (19.50%) followed by diatoms (11.54%), green algae (8.40%), crustaceans (7.29%), blue green algae (3.98%), plant matter (2.79%), worms (2.71%), copepods (1.33%), cladocerans (1.33%), and mollusks (1.33%). All the food items of this fish (% of food- composition) was found vary in monthly. -

Myxozoan infections of redtail catfish Hemibagrus nemurus in freshwater cage cultures K. Molnár1,*, C. Székely1, K. Mohamed2, F. Shaharom-Harrison2 1Veterinary Medical Research Institute, Hungarian Academy of Sciences, PO Box 18, 1581 Budapest, Hungary 2Kolej Universiti Sains & Teknologi Malaysia (KUSTEM), 2130 Kuala Terengganu, Terengganu, Malaysia ABSTRACT: Cage-cultured Asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840), a popular food fish in Southeast Asia, proved to be infected by 3 myxozoan species. All the 3 species belonged to the genus Henneguya: 2 were identified as H. mystusia Sarkar, 1985 and H. hemibagri Tchang et Ma, 1993, while the other was described as H. basifilamentalis sp. n. All plasmodia were found in the gills and were characterised by a specific site selection. H. mystusia formed plasmodia in the multi-layered epithelium between the gill lamellae and in the non-lamellar edge of the gill fil- aments, while H. hemibagri developed in the capillary network of the lamellae. H. basifilamentalis sp. n. had large oval plasmodia located deep among the filaments just above the gill arch.
