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. -

Protecting Eastern Freshwater Cod –Aguide of Food Andshelter
Protecting Eastern Freshwater Cod – a guide for fishers and land managers Eastern Freshwater Cod (also known as Clarence River Cod) is a threatened species under NSW and Commonwealth law. Eastern Freshwater Cod can weigh up to 41 kg but are more commonly less than 5 kg and 660 mm. These large, predatory freshwater fish are native to the Clarence and Richmond Rivers in north-eastern New South Wales. Populations of Eastern Freshwater Cod collapsed in the 1920s and 1930s and continued to decline until the 1980s, when the species was protected. Although once prolific, remnant (non-stocked) populations are now only found in parts of the Clarence River and its tributaries. No remnant populations are known to remain in the Richmond River system, however, stocked populations persist in some local tributaries. Reasons for the decline of Eastern Freshwater Cod include habitat loss and degradation, impacts from introduced Photo by Brett Vercoe species and illegal fishing.

Environmental Impact Statement for Traveston Crossing Dam (Mary River, Queensland): A Review with regard for Species of Concern under the EPBC Act 1999. Report to the Department of Environment, Water, Heritage and the Arts, Canberra. November 2008. xx+84p. iii Executive Summary Queensland Water Infrastructure (QWI) proposes to construct Traveston Crossing Dam on the Mary River as part of a strategy to meet anticipated water demands in south‐ eastern Queensland. This is the last high‐yield dam site available in the region, according to QWI, but it is also an extremely sensitive site in terms of significance for conservation. An Environmental Impact Statement (EIS) has been released for public comment, and a Supplement containing responses to submissions has also been issued. This review is concerned with the implications for a number of species listed under the Environment Protection and Biodiversity Act 1999 (EPBC Act), including three ‘iconic’ species, the Australian lungfish, Mary River cod and Mary River turtle. Context Ecologically Sustainable Development In many cases, the EIS makes assumptions on the basis of scant evidence and draws conclusions about impacts with little or no justification. -

Most have previously documented (e.g. Cadwallader 1978), although been covered in a range of forums, (e.g. previous their impacts have not necessarily been quantified MDBC workshops) and publications (including or mitigated. Many of these threats have been the Native Fish Strategy), often with suggested discussed in detail at previous Murray-Darling solutions. Such threats include: habitat loss, Basin Commission forums with a range of sedimentation, changes to flows, barriers to management recommendations suggested in the movement, interactions with alien species, subsequent publications (Blanch 2001; Phillips fishing (commercial, recreational and illegal), 2001, 2003; Murray-Darling Basin Commission changes to water quality (temperature, salinity, 2004; Lintermans & Phillips 2004; Lintermans et suspended sediment, oxygen), loss to irrigation al. 2005).

Butler1,2,*, Stuart J. Rowland1, Peter R. Baverstock2, Lyndon Brooks2 1Department of Primary Industries NSW, Grafton Fisheries Centre, PMB 2, Grafton, NSW 2460, Australia 2Southern Cross University, Graduate Research College, PO Box 157, Lismore, NSW 2480, Australia ABSTRACT: Movement and migration are fundamental activities in the life history of fishes. It is therefore critical in species conservation that there is a clear understanding of why movements or changes in habitat occur. The aim of the present study was to quantify the movement patterns and habitat selection of the Endangered eastern freshwater cod Maccullochella ikei in relation to river discharge, water temperature and season. Twenty-five adult M. ikei were implanted with radio tags and tracked for 12 mo in the Mann River, Australia. Fish were located manually once a week, whilst larger inter-pool movements were monitored continuously by automated tracking stations. Ten 24 h continuous tracking events were undertaken to quantify diel movement patterns. Under- water cameras were used to verify fixes and observe behaviour. Based on weekly fixes and track- ing station data, 2 main types of behaviour were observed: extended periods of restricted move- ment and strong home-site fidelity, and short periods of relative high mobility and home-site shifts. Larger intra- and inter-pool movements were most often related to rises in river discharge. There was also increased movement and home-site shifts by males but not females during the breeding season.
