Abstract:
Determining the phylogenetic and taxonomic relationships among allopatric populations can be difficult, especially when divergence is recent and morphology is conserved. We used mitochondrial sequence data from the control region and three protein-coding genes (1253 bp in total) and genotypes determined at 13 microsatellite loci to examine the evolutionary relationships among Australia’s largest freshwater fish, the Murray cod, Maccullochella peelii peelii, from the inland Murray–Darling Basin, and its allopatric sister taxa from coastal drainages, the eastern freshwater cod, M. ikei, and Mary River cod, M. peelii mariensis. Phylogenetic analyses provided strong support for taxon-specific clades, with a clade containing both of the eastern taxa reciprocally monophyletic to M. peelii peelii, suggesting a more recent common ancestry between M. ikei and M. peelii mariensis than between the M. peelii subspecies. This finding conflicts with the existing taxonomy and suggests that ancestral Maccullochella crossed the Great Dividing Range in the Pleistocene and subsequently diverged in eastern coastal drainages. Evidence from the present study, in combination with previous morphological and allozymatic data, demonstrates that all extant taxa are genetically and morphologically distinct. The taxonomy of Maccullochella is revised, with Mary River cod now recognised as a species, Maccullochella mariensis, a sister species to eastern freshwater cod, M. ikei. As a result of the taxonomic revision, Murray cod is M. peelii.

Abstract:
Radio telemetry is widely used in studies of freshwater fishes, but the vertical position of fish in riverine environments is rarely reported. The present study tested the application of radio transmitters fitted with depth sensors to determine the vertical position of Murray cod in the lower Ovens River in south-eastern Australia. As the scale of depths in rivers is usually limited (<10 m in the present study), there is a greater need to assess measurement error. The study first involved trials to define depth measurement errors, and a mean relative bias of 9% (range 1.5–14.8%) towards greater depth was recorded. These data were then used to correct the depths recorded from tagged fish. Although data from this preliminary study are somewhat limited, results from the tagged fish showed that by day they all occupied the lower 15% of the water column, indicating that Murray cod exhibit demersal behaviour, using bottom rather than mid-water habitats. Although the present study highlights the importance of tag trials in determining errors, it also indicates the potential application of this technique to understanding the depth-integrated habitat preferences of Murray cod and other species.

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. Lethal salinity concentration in Trout cod and Murray cod larvae was exposure time dependent. The 1 day LC50 of the larvae was 1.97 and 2.33 g/L respectively, compared with the 12 day LC50 values of 0.50 and 0.35 g/L respectively. The threshold (no effect level) salinities of larvae of Trout cod and Murray cod were 0.46 and 0.34 g/L respectively at 12 days exposure. The salinity sensitivities of fry of Murray cod were moderated by increasing pH between pH 6.2 and 8.8, and stimulated by increasing temperatures from 15 to 30°C. The optimal salinity was only slightly affected by temperature. The threshold and upper sublethal salinities varied slightly depending on feeding regime. The salinity sensitivities of fingerlings of Murray cod were: LC50 = 13.7 g/L; optimal salinity from 4.6 to 5.0 g/L ; threshold salinity from 5.9 to 7.4 g/L, and upper sub-lethal salinity from 9.2 to 9.9 g/L � with the range in all cases affected by acclimation period salinity. The blood osmolality at LC50 of the fingerlings was 444 mOsmol/kgH2O or equivalent to 14.2 g/L, and the dehydration rate was 4.8%. The osmolality increased significantly in salinities higher than 9.0 and 6.0 g/L when fish were exposed for a period of 1 day and 41 days respectively. The oxygen consumption increased significantly in salinities higher than 8.0 g/L. Distortion of the notochord and corrosive skin syndrome were major symptoms describing sub-lethal effects found in the embryos, and fry and fingerlings of Murray cod respectively. Noting the risks of extrapolating directly from laboratory to field conditions, it is predicted that when salinity in natural habitats increases above 0.34 g/L a significant impact on Murray cod recruitment will result.

Abstract:
<em>Abstract</em> .—The collection and use of data to manage the freshwater fisheries of Australia’s Murray–Darling basin (MDB) has a poor history of success. While there was limited assessment data for early subsistence and commercial fisheries, even after more robust data became available during the 1950s its quality varied across jurisdictions and was often poorly collated, assessments were not completed, and the data were underutilized by management. The fishery for Murray Cod <em>Maccullochella peelii </em> is given as an example, where the fishery declined to the point of closure and then the decline continued to the extent that Murray Cod was listed as a threatened species and all harvest now only occurs through the recreational fishery. Lessons from such poor population assessments have not been fully learned, however, as there remains a paucity of harvest data for this recreational fishery. Without a proper assessment, a true economic valuation of this fishery has not been made. As the MDB is Australia’s food bowl, there are competing demands for water use by agriculture, and without a proper assessment of the worth of the fishery, it is difficult for Murray Cod to be truly considered in either economic or sociopolitical discussions. The poor state of MDB rivers and their fish populations (including Murray Cod) has, however, resulted in political pressure for the development of the sustainable rivers audit, a common assessment method for riverine environmental condition monitoring. This audit undertakes standardized sampling for fish and a range of other variables at a number of fixed and randomly selected sites on a 3-year rotating basis. While the sustainable rivers audit has provided a range of data indicating that the condition of rivers is generally very poor, these data have yet to be fully utilized to determine the potential state of the fisheries (such as Murray Cod) or to set targets for rehabilitation, such as for environmental flows. While, to date, data analyses have been somewhat restricted by fiscal constraints, more comprehensive use of data, together with full fishery valuations, should be seen as the way forward for improved management.

Abstract:
<em>Abstract</em>.—The Murray-Darling basin produces about 40% of the total value of Australia’s agricultural output from 1.9 million ha of irrigated agriculture that represents around 75% of the nation’s total irrigation. Major reservoirs in the southeastern states regulate the basin’s river systems for irrigation but also provide recreational fisheries. One of these storages is Lake Eppalock in the state of Victoria, a multi-use impoundment built in 1964 covering 3,230 ha and holding 312,000 ML at full supply level. It has been actively developed as a mixed species recreational fishery (golden perch <em>Macquaria ambigua </em>and Murray cod <em>Maccullochella peeli</em>) and is a popular angling water. The principal recreational target species in the lake compete with invasive pest species (common carp [also known as European carp] <em>Cyprinus carpio</em>). Drought is part of the natural variability of the Australian climate and its rainfall history features several periods of a decade or longer that have been distinctly drought-prone. Eastern Australia was in the eighth year of the latest drought cycle in 2007, and Lake Eppalock had fallen to less than 1% of its full supply level. These conditions highlighted increasing competition for water and brought into focus the interdependence and linkages between fisheries management and water needs, both for irrigation and for the environment. Fisheries managers faced a very strong likelihood of extensive fish deaths in the lake and elsewhere that could cause significant long-term impacts requiring many years to recover the recreational fishery. A planned partnership approach with the storage water authority was adopted in 2006 for integrated fisheries and water management, with response actions targeted to achieve storage conditions ensuring the maximum survivability of key recreational angling species in the lake through the drought. The framework for cooperation established in this study provides an example for future water allocation disputes.
