This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus.

  • REVOLUTIONISING Inland Fish Production and Stocking in Victoria “WE GROW YOUR FISH”
    REVOLUTIONISING Inland Fish Production and Stocking in Victoria “WE GROW YOUR FISH” Prepared by the Snobs Creek Advisory Board Introduction The Victorian Fisheries Authority (VFA) has a long and successful history of growing and stocking fish to recover threatened species, build fish populations and create fantastic recreational fishing opportunities in Victoria. Most of our waterways are heavily modified and no longer consistently provide conditions that support natural breeding for fish. Therefore, fish stocking is an essential and powerful tool for maintaining fish populations and good fishing, alongside river restoration activities including habitat rehabilitation and environmental flows. In Victoria over 200 waters are stocked annually with twelve different fish species. These include both native threatened fish such as Murray cod, golden perch, trout cod, Macquarie perch, silver perch, catfish, Australian bass, and estuary perch, and popular introduced recreational fish species such as brown trout, rainbow trout, chinook salmon, brook trout.

  • Conservation Advice Galaxias Johnstoni Clarence Galaxias
    THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister’s delegate approved this Conservation Advice on 16/12/2016 . Conservation Advice Galaxias johnstoni Clarence galaxias Conservation Status Galaxias johnstoni (Clarence galaxias) is listed as Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) effective from 16 July 2000. The species was eligible for listing under the EPBC Act as on 16 July 2000 it was listed as Endangered under Schedule 1 of the preceding Act, the Endangered Species Protection Act 1992 (Cwlth). Species can also be listed as threatened under state and territory legislation. For information on the current listing status of this species under relevant state or territory legislation, see http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl . The main factors that make the species eligible for listing in the Endangered category are that the Clarence galaxias had experienced past decline, it had a limited distribution in central Tasmania that was severely fragmented and continuing decline was inferred given the presence of introduced fish species in areas where some of the populations occur (TSS 2006). Description The Clarence galaxias, family Galaxiidae, is a small, stout freshwater fish, reaching a maximum length of approximately 140 mm (Allen et al., 2002; TSS 2006). Adults are dark brown in colour with irregular brown bars or blotches on the back and sides, tending to a yellow belly (Allen et al., 2002; TSS 2006). Numerous very small black spots are often present, but these are parasites in the skin rather than natural markings of the species (Fulton 1990).

  • SALINITY SENSITIVITY in EARLY LIFE STAGES of an AUSTRALIAN FRESHWATER FISH, MURRAY COD (Maccullochella Peelii Peelii Mitchell 1838)
    i SALINITY SENSITIVITY IN EARLY LIFE STAGES OF AN AUSTRALIAN FRESHWATER FISH, MURRAY COD (Maccullochella peelii peelii Mitchell 1838) Piyapong Chotipuntu THESIS SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY OF THE UNIVERSITY OF CANBERRA Submitted August 2003 ii © Piyapong Chotipuntu 2003 Abstract The Murray cod (Maccullochella peelii peelii Mitchell 1838) is Australia’s largest freshwater fish. Once highly abundant in the Murray-Darling river system, populations have drastically declined in recent decades. Many causes for this decline have been proposed, including over-fishing, habitat loss and altered river flow regimes. This study hypothesised that elevated salinities have led to selective mortality in some developmental stages, which have in turn depleted stock recruitment and adult populations. The objectives of this study were to determine the optimal, threshold, upper sublethal and lethal salinities for development of eggs, yolk-sac larvae, fry and fingerlings of M. peelii peelii. Investigation the impact of salinity on fertilisation utilised gametes of trout cod (M. macquariensis, Cuvier 1829) instead of M. peelii peelii. Studies were carried out in a controlled laboratory environment using test media prepared from commercial sea salt. The results showed that the eggs of the trout cod hatched only when fertilised and incubated in freshwater, and only larvae hatched in freshwater survived through the yolk absorption period of 12 days. Yolk utilisation efficiencies were not significantly different among the salinities of 0-0.30 g/L. There was no effect of pre- or post- fertilising processes on the salinity tolerances of yolk-sac larvae. No larvae survived at salinities higher than 0.30 g/L during the yolk utilisation period.
