  • Mogurnda Adspersa - Purple Spotted Gudgeon
    Fisheries Scientific Committee November 2006 Ref. No. PR35 File No. FSC 00/15 PROPOSED DETERMINATION Mogurnda adspersa - Purple spotted gudgeon The Fisheries Scientific Committee, established under Part 7A of the Fisheries Management Act 1994 (the Act), is proposing to omit Mogurnda adspersa - purple spotted gudgeon from Part 2 of Schedule 4 Endangered Populations of the Act and insert Mogurnda adspersa - purple spotted gudgeon into Part 1 of Schedule 4 Endangered Species of the Act. The amendment of the threatened species lists is provided for by Part 7A, Division 2 of the Act. The Fisheries Scientific Committee, with reference to the criteria relevant to this species, prescribed by Part 11B of the Fisheries Management (General) Regulation 2002 (the Regulation) has found that: Background 1. Mogurnda adspersa - purple spotted gudgeon is a valid, recognised taxon and is a species as defined in the Act. 2. Purple spotted gudgeon are found in slow moving or still waters of rivers, creeks and billabongs, often amongst weeds, rocks and snags. 3. They feed mainly on insect larvae, but also consume worms, tadpoles, small fish and some plant matter. 4. Female Mogurnda adspersa may lay several batches of eggs per season (30-1,300 per batch). The eggs are deposited in clusters on solid objects such as rocks, wood or broad-leafed plants. The male guards and fans the eggs until hatching (3-8 days). 5. Mogurnda adspersa - purple spotted gudgeon has the following conservation status: i. NSW Fisheries Management Act 1994 : Endangered Population; ii. IUCN 2004: - no listing; iii. Victoria Flora and Fauna Guarantee Act 1988 : - Threatened; iv.

(HONS.) JONATHAN COID MARSHALL B.SC. (HONS.) FACULTY OF ENVIRONMENTAL SCIENCES GRIFFITH UNIVERSITY QUEENSLAND AUSTRALIA Submitted in fulfilment of the requirements of the degree of Doctor of Philosophy MARCH 2001 ABSTRACT Previous research has shown that a range of physical and biological drivers can influence the composition of faunal assemblages occupying localities within streams. There is much debate in the literature about which of these is more important. Descriptive and experimental field studies were conducted in two relatively undisturbed, second order rainforest streams in southeast Queensland, Australia. The principal objectives were to describe spatial and temporal patterns in pool fauna and explore relationships between these patterns and physical attributes of habitat, disturbance and biotic interactions. The macroinvertebrate and vertebrate fauna of 12 small stream pools were sampled approximately monthly over a period of 15 months. Samples were collected from all major within-pool habitat types and concurrent measurements of potentially important environmental parameters were made at landscape scales of stream, pool and habitat patch. Faunal assemblages were consistently different between the two streams and between the various within-pool habitat types, although the latter may partially be explained by differences in sampling protocols applied in the different habitat types.

HAMMER1,2, MARK ADAMS2 & RALPH FOSTER3 1 Natural Sciences, Museum and Art Gallery of the Northern Territory, PO Box 4646 Darwin NT 0810, Australia. E-mail: [email protected] 2Evolutionary Biology Unit, South Australian Museum, Adelaide SA 5000, Australia. E-mail: [email protected] 3Ichthyology Section, South Australian Museum, Adelaide SA 5000, Australia. E-mail: [email protected] Abstract South Australia is a large Australian state (~1,000,000 km2) with diverse aquatic habitats spread across temperate to arid environments. The knowledge of freshwater fishes in this jurisdiction has advanced considerably since the last detailed catalogue of native and alien species was published in 2004 owing to significant survey and research effort, spatial analysis of museum data, and incidental records. The updated list includes 60 native and 35 alien species. New additions to the native fauna include cryptic species of Retropinna semoni s.l. (Weber) and Galaxias olidus s.l. (Günther). Two others have been rediscovered after long absences, namely Neochanna cleaveri (Scott) and Mogurnda adspersa (Castelnau). Range extensions are reported for native populations of Galaxias brevipinnis Günther, Leiopotherapon unicolour (Günther), Hypseleotris spp. (hybridogenetic forms) and Philypnodon macrostomus Hoese and Reader.
