Red‐finned Blue‐eyes are found in artesian springs on a single property ‘Edgbaston Station’ that was bought by Bush Heritage Australia to protect the Blue‐eyes, Edgbaston Gobies, and a number of other plants and aquatic invertebrates that occur nowhere else. Red‐finned blue‐eyes are threatened by the introduced mosquito fish (Gambusia holbrooki) an aggressive pest fish that preys upon the eggs and juveniles of many native fish species. BHA is trailing methods to control mosquito fish numbers and prevent them from entering more of the springs. ANGFA Qld is hoping to start a captive breeding programme to reduce the extinction risk for the species. Red‐finned Blue‐eyes are listed as Endangered under the federal Environment Protection and Biodiversity Conservation Act and the Queensland Nature Conservation Act. Red‐finned Blue‐eyes are a “no‐take” species. More information at Home of the Rainbowfish. Chlamydogobius squamigenus (Edgbaston Goby) © Gunther Schmida Edgbaston Gobies are only found in the artesian springs of Edgbaston Station along with the Red‐finned Blue‐eye. Australia has a number of species of desert gobies that only occur in particular springs or water courses. Those that occur in artesian springs are especially at risk from habitat destruction as the springs are often damaged by stock watering and their flows and water levels can be impacted by water harvesting through artesian bores. Male Edgbaston Gobies have a head and body colour of dusky greyish yellow; the head is whitish‐ yellow underneath. They have indistinct narrow grey bars and mottling across the upper half of the body. The head is plain greyish‐yellow with a pale gold iris. The dorsal fin is blackish with a narrow chrome yellow submarginal band. The band is widest anteriorly, becoming narrower and darker posteriorly. A broad vivid blue band runs across the centre of the fin while the lower third of the fin is blackish. The second dorsal and anal fins are blackish with a broad bright greyish blue margin. The second dorsal fin has a diffuse greyish blue band across proximal half of fin. The caudal fin is very dark‐grey with a narrow dull whitish grey margin. Indistinct vertically aligned rows of yellowish to light grey spots are present. They can be distinguished from other Chlamydogobius species by the presence of scales on the cheeks. Males in breeding condition become quite colourful. Pseudomugil mellis (Honey Blue‐eye) © Gunther Schmida Honey Blue‐eyes are a wallum species, from the swamps and streams of coastal heathlands. Aquarium collecting, pest fish, and habitat degradation have contributed to their disappearance from much of their original distribution. ANGFA Qld members maintain captive populations of Honey Blue‐eyes and encourage others to keep them in ponds, farm dams, and aquaria. They are an excellent choice for backyard ponds because of their small size, wide temperature tolerance, and vibrant colouration. We also assist with and encourage the rehabilitation of degraded urban waterways and wetlands. Honey Blue‐eyes are listed as Vulnerable under the federal Environment Protection and Biodiversity Conservation Act and the Queensland Nature Conservation Act. Honey Blue‐eyes are a “no‐take” species. More information at Home of the Rainbowfish. Rhadinocentrus ornatus (Ornate Rainbowfish) © Gunther Schmida Ornate Rainbowfish, also known as Soft Spined Sunfish, occur in coastal streams. There are many genetically distinct populations showing a variety of colours and patterns including red, blue, yellow, olive, and black in a variety of patterns. ANGFA Qld members maintain captive populations of distinct varieties from known locations and encourage the keeping of captive bred fish by aquarium hobbyists. While they are not listed under the Environment Protection and Biodiversity Conservation Act and the Queensland Nature Conservation Act some populations have declined or disappeared so they have been listed as a significant species in the Brisbane City Council Planning Scheme. There is a take and possession limit of 20 Ornate Rainbowfish under the Queensland Fisheries Act. More information at Home of the Rainbowfish. Nannoperca oxleyana (Oxleyan Pygmy Perch) © Gunther Schmida Oxleyan Pygmy Perches are a wallum species, from the swamps and streams of coastal heathlands. They rely on riparian and emergent vegetation and/or undercut banks for protection. Habitat degradation has probably played a significant role in decreasing naturally small populations. ANGFA Qld members maintain captive populations as well as assisting with and encouraging the rehabilitation of degraded urban waterways and wetlands. Oxleyan Pygmy Perches are listed as Endangered under the federal Environment Protection and Biodiversity Conservation Act and as Vulnerable under the Queensland Nature Conservation Act. More information at the Department of Environment and Heritage Protection. Kuhlia rupestris (Jungle Perch) © Gunther Schmida Jungle perch are a freshwater species that must return to saltwater to breed. They are a popular sport, table, and aquarium fish that have disappeared from many river systems along the Queensland coastline. Their decline is thought to be mostly a result of habitat degradation, with overhanging vegetation removed from many waterways, and barriers to migration, with dams and weirs preventing adult fish from moving downstream to breed and preventing juvenile fish from moving upstream to freshwater habitats. Fisheries researchers from DAFF are developing captive breeding techniques so that suitable waterways may be restocked. Removal or modification of barriers and habitat restoration may help the recovery of Jungle Perch populations. Jungle perch are not listed under the Environment Protection and Biodiversity Conservation Act and the Queensland Nature Conservation Act. There is a combined take and possession limit of 1 Jungle Perch or 1 Spotted Flagtail under the Queensland Fisheries Act. More information at the Australian Museum. Neoceratodus forsteri (Queensland Lungfish) © Gunther Schmida The Queensland Lungfish is scientifically a very important species. It is a “fleshy‐finned” fish, of which there are only six species worldwide. It is probably the closest living fish to those that evolved to become amphibians and hence, all terrestrial vertebrates. Fossils similar to Lungfish date back 380 million years, approximately the time when higher vertebrate classes began evolving. It has remained virtually unchanged for at least 100 million years. The only natural populations occur in Queensland’s Mary and Burnett river systems. They are threatened by barriers to movement (dams and weirs) and altered flow regimes, with the long‐lived adult fish needing to migrate upstream into fast‐flowing shallow waters to breed. Lungfish are listed as Vulnerable under the federal Environment Protection and Biodiversity Conservation Act. Lungfish are a “no‐take” species. More information at the Australian Museum.

  • Final Report Ornate Rainbowfish, Rhadinocentrus Ornatus, Project
    Final Report Ornate Rainbowfish, Rhadinocentrus ornatus, project. (Save the Sunfish, Grant ID: 19393) by Simon Baltais Wildlife Preservation Society of QLD Bayside Branch (QLD) inc. (Version: Saturday, 25 June 2011) 1 1. Introduction 1.1 Background The Rhadinocentrus ornatus (Ornate Sunfish, soft spined sunfish, or Ornate Rainbowfish) is a freshwater rainbowfish from the Family Melanotaeniidae. This Melanotaeniidae family of fish is only found in Australia and New Guinea. It’s a small, mainly insectivorous species, the largest individuals reaching a maximum length of approximately 80mm (Warburton and Chapman, 2007). The Rhadinocentrus ornatus (R. ornatus) is said to be a small, obligate freshwater fish species restricted to the coastal wallum habitat of eastern Australia (Hancox et al, 2010), where waters are slow flowing and acidic, and submerged and emergent vegetation is plentiful (Warburton and Chapman, 2007). However, Wildlife Queensland has found this species utilising other habitat types, such as gallery rainforest along Tingalpa Creek West Mt Cotton, a finding supported by BCC (2010). Good populations of R.ornatus were particularly found in clear slow – medium flowing streams supporting no aquatic or emergent vegetation located within gallery rainforest. The species was particularly common in 12.3.1 Gallery rainforest (notophyll vine forest) on alluvial plains (Endangered) within a landscape comprised of 12.11.5 Open forest complex with Corymbia citriodora, Eucalyptus siderophloia, E. major on metamorphics ± interbedded volcanics

Hatching success of rainbowfish eggs following exposure to air Lois Oulton, Penelope Carbia, and Culum Brown Macquarie University KEYWORDS egg desiccation, Lake Eacham, Melanotaenia, translocation ABSTRACT Translocation of fishes within and between drainage basins is widely recognised as a threatening process to Australian native fishes. While many translocations are deliberate, for example for fisheries enhancement, it is possible that translocation can occur naturally. In the Wet Tropic region of Australia, the widespread eastern rainbowfish, Melanotaenia splendida, has begun to colonise the Atherton tablelands. This is of particular concern because the area is home to several endangered endemic species such as the Lake Eacham rainbowfish, M. eachamensis, and its allies. It is likely that some of the translocations have occurred through the use of this species as bait, but the recent invasion of Lake Eacham may have occurred naturally via the movement of eggs between nearby streams running into Lake Tinaroo.

    CSIRO PUBLISHING www.publish.csiro.au/journals/mfr Marine and Freshwater Research, 2004, 55, 165–172 Deep phylogenetic structure has conservation implications for ornate rainbowfish (Melanotaeniidae : Rhadinocentrus ornatus) in Queensland, eastern Australia Timothy J. PageA,B, Suman SharmaA and Jane M. HughesA ACooperative Research Centre for Freshwater Ecology, Centre for Riverine Landscapes, Faculty of Environmental Sciences, Griffith University, Nathan Campus, Qld. 4111, Australia. BCorresponding author. Email: [email protected] Abstract. The freshwater fish, Rhadinocentrus ornatus Regan, 1914, has a patchy distribution through coastal drainages of Queensland and New South Wales, eastern Australia. Isolated populations of R. ornatus are found on several islands, as well as in a disjunct northern population 350 km from its nearest conspecific population. Deoxyribonucleic acid was extracted and sequenced for the mitochondrial ATPase gene to describe the geographic and genetic subdivision within the species. Four major clades were identified. These clades diverged between two and seven million years ago and so represent long-term divisions and possible units of conservation. There are conservation implications in that the narrow and localised distribution of R. ornatus overlaps with an area of large- scale land clearing, high human population and threats from introduced exotic fish. A particularly high centre of Rhadinocentrus diversity in the Tin Can Bay area of Queensland presents some interesting questions about the evolution of the genus Rhadinocentrus. Extra keywords: ATPase, mitochondrial DNA, phylogeography, wallum. Introduction Rhadinocentrus ornatus Regan, 1914 (Melanotaeniidae) Allopatric populations of obligate freshwater fish of the same is a small, iridescent obligate freshwater fish with recognised species are prone to localised differentiation and adaptation, colour variation in its second dorsal and anal fins (Hansen as well as extinction, by the very nature of their specific 1992).

  • Thesis Submitted in Fulfilment of the Requirements for the Degree of Masters of Science by Research
    Factors influencing hybridisation and introduction success of the critically endangered Running River rainbowfish, Melanotaenia sp. Karl Moy B. Zool. (Hons) Institute for Applied Ecology University of Canberra A thesis submitted in fulfilment of the requirements for the degree of Masters of Science by Research 7th of August 2019 i Abstract Given that conservation introductions are essentially biological invasions, researching the main factors which influence them will provide insight for both conservation and management. The factors affecting invasion success in small-bodied Australian freshwater fishes are largely unstudied. From a conservation-oriented perspective this is worrying as small-bodied freshwater species are more likely to become threatened than large-bodied species. It is equally concerning from an invasive species management perspective as many species have the potential to negatively impact native species and ecosystems. This thesis consists of two data chapters preceded by a general introduction and followed by a synthesis. The first data chapter examines potential pre and post zygotic barriers to hybridisation between the Running River rainbowfish (RRR) and eastern rainbowfish (Melanotaenia splendida). Eastern rainbowfish is a widespread native fish of northern Australia with an alien population in Running River (a tributary of the Burdekin River, Queensland). Hybridisation between RRR and eastern rainbowfish has been detected and in the absence of barriers to further hybridisation and introgression will likely lead to the loss of pure RRR from the wild. Dichotomous mate choice experiments and egg survival experiments were used to determine the presences of pre and post-zygotic barriers to hybridisation between RRR and eastern rainbowfish. The findings of this study do not support the presence of barriers to hybridisation between the two species.

Sequences of mitochondrial DNA ATPase 8 and 6 genes, and morphometric data, were used to find population structuring. Specimens were collected from 7 locations in the southern region of Western Ghats, a global biodiversity hotspot in India. Biometric analysis revealed apparent heterogeneity in the morphology and color pattern between the species at juvenile and adult stages, and among different geographically separated populations of these species. High values for mean pair wise distances and a high proportion of the total variance attributed to differences between the geographically isolated populations with AMOVA, indicated clear population structuring within these species. Extremely high values for Pair wise FST and significantly lower Nm values observed among the populations studied, suggested little or no effective gene flow among them. Constructed phylogenies further confirmed a high degree of population structuring within the species, showing local endemism with population specific haplotypes forming a species complex.

  • Australia's Place in the Cosmopolitan World of Indo-West Pacific
    Molecular Phylogenetics and Evolution 43 (2007) 645–659 www.elsevier.com/locate/ympev An island in the stream: Australia’s place in the cosmopolitan world of Indo-West Pacific freshwater shrimp (Decapoda: Atyidae: Caridina) Timothy J. Page a,*, Kristina von Rintelen b, Jane M. Hughes a a Australian Rivers Institute, Faculty of Environmental Sciences, Griffith University, Nathan Campus, Qld., 4111, Australia b Museum of Natural History, Humboldt-University Berlin, Invalidenstrasse 43, D-10115, Berlin, Germany Received 3 May 2006; revised 5 August 2006; accepted 8 August 2006 Available online 18 August 2006 Abstract Mitochondrial DNA sequences were used to investigate phylogenetic and biogeographic relationships among Australian freshwater shrimp from the genus Caridina H. Milne Edwards, 1837 (Atyidae) and congeners from potential source populations throughout the Indo-West Pacific region. Numerous Australian taxa have close evolutionary relationships with non-Australian taxa from locations throughout the region, indicating a diverse origin of the Australian freshwater fauna. This implies many colonisations to or from Aus- tralia over a long period, and thus highlights the surprising adeptness of freshwater shrimp in dispersal across ocean barriers and the unity of much of the region’s freshwater biota. Interestingly, a study on Australia’s other main genus of atyid shrimp, Paratya Miers, 1882, inferred only a single colonisation. A number of potential species radiations within Australia were also identified. This agrees with patterns detected for a large number of Australian freshwater taxa, and so implies a vicariant explanation due to the development of colder, dryer climates during the late Miocene/early Pliocene.
