Abstract:
Interactions between turtle hatchlings of Chelodina oblonga and the marron, Cherax tenuimanus, the gilgie, C. quinquecarinatus, the koonac, C. preissii (freshwater crayfish native to Western Australia) and the introduced yabby, Cherax. sp., were observed in laboratory-based trials in uncluttered aquaria. Marron, koonacs and yabbies, but not gilgies, showed aggressive and predatory behaviour towards the hatchlings. In total, 59 attacks were observed in 26 of the 80 trials. On 12 occasions, crayfish captured hatchlings in their chelae. On two occasions, the attack of the crayfish was so quick that the hatchling was killed instantly. Compared with movement when alone, movement of hatchlings was significantly greater in the presence of koonacs and yabbies, but significantly less in the presence of marron and gilgies. The range of non-native yabbies currently is expanding into Ellen Brook Nature Reserve which harbours the last naturally persisting population of the critically endangered western swamp turtle, Pseudemydura umbrina. No native crayfish occur in the habitat of P. umbrina in this reserve. The possible invasion by the ecological generalist yabby poses a new threat to the survival of P. umbrina.

Abstract:
Laboratory mesocosm incubations were undertaken to investigate the influence of burrowing shrimp Trypaea australiensis (marine yabby) on sediment reworking, physical and chemical sediment characteristics and nutrients in sandy sediments receiving mangrove (Avicennia marina) leaf litter. Mesocosms of sieved, natural T. australiensis inhabited sands, were continually flushed with fresh seawater and pre-incubated for 17 days prior to triplicates being assigned to one of four treatments; sandy sediment (S), sediment + yabbies (S+Y), sediment + leaf litter (organic matter; S+OM) and sediment + yabbies + leaf litter (S+Y+OM) and maintained for 55 days. Mangrove leaf litter was added daily to treatments S+OM and S+Y+OM. Luminophores were added to mesocosms to quantify sediment reworking. Sediment samples were collected after the pre-incubation period from a set of triplicate mesocosms to establish initial conditions prior to the imposition of the treatments and from the treatment mesocosms at the conclusion of the 55-day incubation period. Yabbies demonstrated a clear effect on sediment topography and leaf litter burial through burrow creation and maintenance, creating mounds on the sediment surface ranging in diameter from 3.4 to 12 cm. Within S+Y+OM sediments leaf litter was consistently removed from the surface to sub-surface layers with only 7.5% ± 3.6% of the total mass of leaf detritus added to the mesocosms remaining at the surface at the end of the 55-day incubation period. Yabbies significantly decreased sediment wet-bulk density and increased porosity. Additionally, T. australiensis significantly reduced sediment bio-available ammonium (NH4+bio) concentrations and altered the shape of the concentration depth profile in comparison to the non-bioturbated mesocosms, indicating influences on nutrient cycling and sediment-water fluxes. No significant changes for mean apparent biodiffusion coefficients (Db) and mean biotransport coefficients (r), were found between the bioturbated S+Y and S+Y+OM mesocosms. The findings of this study provide further evidence that T. australiensis is a key-species in shallow intertidal systems playing an important role as an ‘ecosystem engineer’ in soft-bottom habitats by significantly altering physical and chemical structures and biogeochemical function.

Full text
Abstract:
Exotic finfish and crayfish have been translocated into Western Australia for more than 100 years. Deliberate stocking and subsequent escape from man-made impoundments have resulted in widespread distribution of non-native yabbies (Cherax albidus) and the exotic redfin perch (Perca fluviatilis) in the State’s south-west. Both species are considered invasive and are known to compete with indigenous species for resources. The nature and degree of impact on native marron (Cherax cainii) is unclear and the subject of current debate. Other researchers have hypothesised that invasive species modify their behaviour in the presence of predators in a more rapid and advantageous manner than native species. This greater behavioural plasticity can result in displacement of indigenous species and successful colonisation of invaders. The aim of this study was to investigate behavioural responses of an indigenous crayfish (C. cainii) and an invasive crayfish (C. albidus) to odours from a native predator (Tandanus bostocki) and an exotic predatory fish (P. fluviatilis) present in Western Australia. Crayfish behaviour was observed in individual glass tanks following the addition of odours from native (T. bostocki) or exotic (P. fluviatilis) finfish predators. Marron exhibited minor behavioural modifications when presented with odours from native or exotic finfish. In contrast, the invasive yabby showed greater detection of odours, displaying significant changes in behaviour (P < 0.05). Yabbies also appeared to distinguish between food odour (commercial crayfish feed) and predator odour; however, neither marron nor yabbies displayed behaviour indicating that they could distinguish between a native or exotic fish predator. Results support the hypothesis that invasive crayfish species have a greater capacity for behavioural plasticity than non-invasive crayfish.

Full text
Abstract:
Freshwater crayfish support significant commercial and recreational fisheries worldwide. The genus Cherax is fished in Australia with a variety of fishing gears, yet little is known of the relative efficiency of the different fishing gears and methods. Additionally, freshwater-crayfish traps can pose a risk to air breathing by-catch such as aquatic mammals, reptiles and birds, so by-catch mitigation is important. We sought to understand whether freshwater-crayfish fishing can be undertaken efficiently, using passive traps and nets, without undue risk to air-breathing by-catch species. In field-experiments, we compared the efficiency of six gear types and tested the effect of five exclusion rings on catch performance over three soak times. The efficiency of gear types varied significantly by soak times. In productive locations, catch can be maximised by repeatedly deploying open-topped gear for short soak times. Opera-house traps fitted with fixed entrance rings (45–85-mm diameter) were not size-selective for yabbies. Encouragingly, open-topped gear and opera-house traps fitted with fixed ring entrances much smaller than many commercially available (45-mm diameter) still fish effectively for yabbies. We believe that smaller fixed ring-entrance size is likely to be correlated with a reduced risk of by-catch for air-breathing fauna.

Abstract:
The high degree of morphological variability exhibited by yabbies (Cherax destructor Clark and C. albidus Clark) prompted this investigation of genetic variation, specifically addressing the taxonomy and population structure of these freshwater crayfish. Yabbies from 14 localities in South Australia and Victoria were classified morphologically and examined electrophoretically at 35 gene loci. Morphometric analysis confirmed the existence of two morphotypes with allopatric distributions. Genetic divergence between morphotypes was relatively low (average fixed differences = 4.72%, average Nei D = 0.085) compared with known interspecific levels-both generally and within the genus Cherax-and levels of divergence between populations within the morphotypes. Subspecific status for albidus is consequently advocated. This species shows evidence of a high degree of genetic fragmentation, with significant heterogeneity occurring at two or more loci between even the closest localities. Gene flow appears to be severely restricted even within drainage basins and a 'stepping-stone' model of population structure may be appropriate. This high degree of genetic fragmentation may explain the variable morphology of this species although phenotypic plasticity could also play a role. Genetic variation was chaotically distributed (the only consistent geographic pattern of divergence corresponding to the albidus morphotype), probably reflecting numerous translocations of this species. The results highlight the need for taxonomy and management to be based on genetic as well as morphological subdivisions.

Full text
Abstract:
The assertion that invasive species show higher plasticity in the use of information than indigenous ones was analysed in an indigenous crayfish Cherax tenuimanus (marron) and the non-indigenous C. albidus (yabby) in temperate Western Australia. In the laboratory, both species displayed a measurable change in their behaviour when presented with odours produced by food and by damaged conspecifics. They also reacted to heterospecific cues, possibly because ~70 years of sympatry had led the two species to learn each other’s alarm signals. However, this may be explained as a case of phylogenetic inertia and/or may be related to similar mechanisms of chemical detection. Yabbies displayed shorter reaction times and clearer changes in their body posture to heterospecific odours than did marron, supporting the view that invasive crayfish make faster and more appropriate use of information than those species they are displacing.

Full text
Abstract:
Blackwater contains high levels of dissolved organic carbon that can be rapidly consumed by microbes, sometimes leading to extremely low levels of dissolved oxygen (hypoxia) and drastic consequences for aquatic life, including fish kills. Drought-breaking rains in late 2010 inundated large areas of the Barmah–Millewa Forest, southern Murray–Darling Basin, Australia, and resulted in a prolonged hypoxic blackwater event within the forest and the Murray River downstream. This study investigated the short-term effects of the blackwater event on fish and crayfish. Compared with non-affected sites, blackwater affected sites had: significantly higher abundances of emerged Murray crayfish (Euastacus armatus) that were vulnerable to desiccation, predation and exploitation; large numbers of dead or dying shrimp and yabbies; significantly reduced abundances of native fish; but contained similar abundances of alien fish species (particularly common carp, Cyprinus carpio). The nature of the mechanisms that caused these changes and the longer term significance of the event on the river system remains an important area for future research. We also propose a range of management considerations for reducing the blackwater impacts, such as the timing of environmental water delivery after prolonged drought and the importance of maintaining river–floodplain connectivity during flood periods.

Abstract:
<p>Many hatcheries successfully produced and sold cherax as ornamental crayfish. The attempt to culture cherax in earthen pond to produce consumable size yabbies facing the fact that cherax is a good hole digger and usually escapes through the hole in dyke. Single-o-shelter meant to provide shelter for every single spawner as well as hideout for the juvenile produced. The shelter for spawner was a 25 inches long and 2.0 inches diameter PVC pipe randomly spread on pond bottom. Aquatic weed (Vallisneria torta) grew in the shallow part of pond to provide hiding place for juvenile. The species stocked is huna and redclaw, each at density of 2 and 6 sets of spawner. One set of spawner consists of 3 males and 5 females weighing averagely around 20 g each. The experimental units are randomly selected to facilitate random block design in 2 rearing period as replicate. The pond dimension is 10 m x 10 m, divide into 3 compartments i.e. feeding, ground, nursery ground and harvest ditch. Water depth at nursery ground was 30 cm and at the other compartments at 60 cm. Follow gravity force, the water in ponds flows at 50—100 L minute-1. Self-made diet distributed into pond twice a day to meet 3% daily feeding ration. Survival rate and specific growth rate of spawner as well as juvenile produced and number of gravid female checked at the end of each rearing period or every 3 months. After 6 months, average weight of redclaw and huna reaching 146.12 ± 34.47 g and 103.7 ± 29.83 g, respectively. Redclaw produced progeny of 5 size groups and huna produced only 2 groups. Respective to the species, average weight of the first offspring batch was 39.03 ± 5.33 and 26.83 ± 2.09 g. Redclaw at 2 sets of spawner and male grow faster than of 6 sets of spawner and female. No survival rate significant difference among ponds indicates that single–o-shelter technique provides sufficient shelter for spawner to grow and reproduce. Male monosex redclaw culture in earthen pond seems to be more promising than mixed-sex and female monosex culture for consumable size production of either huna or redclaw.</p>

Full text
Abstract:
This study tested the hypothesis that the introduced yabbie Cherax destructor Clark, 1936 has the potential to compete with the endemic marron Cherax cainii Austin, 2002 for food resources. Multiple stable isotope analyses were conducted in the Hutt River, Western Australia, in summer (December) and winter (July), 2003. Summer samples indicated that these species occupied similar predatory trophic positions when their assimilated diet consisted of a large proportion of Gambusia holbrooki. Although C. cainii continued to assimilate mostly animal matter based on winter signatures, those of C. destructor appeared to shift towards a more herbivorous trophic position. The study suggests that C. destructor and C. cainii may be keystone species in the Hutt River, possibly altering the cycling of nutrients and structure of the aquatic food web since their introduction into this system. The ecological implications of the continued invasion of C. destructor into the aquatic systems of south-western Australia, particularly with regard to competition with the other endemic freshwater crayfishes, are discussed.
