“…A single study reports that growth of O. angasi in Tasmanian waters slowed significantly over the colder austral autumn and winter months (MaySeptember) (Mitchell et al, 2000). The preferred salinity range of O. angasi is 26-36 (Nell & Livanos, unpublished data, in Nell and Gibbs, 1986; reported as 25-35 g l −1 ), though the oyster can tolerate salinities of 21-46 (Nell and Gibbs, 1986; reported as 20-45 g l −1 ). Two east coast locations, representative of different environmental regimes within the range of O. angasi's geographic distribution were selected to conduct in situ field culture experiments: Pambula Lake, on the far south coast of New South Wales and Little Swanport, located on the mid-east coast of Tasmania (Fig.…”

“…This is not an unreasonable assumption given that spawning and larval settlement of S. glomerata in Port Stephens extends from November to May/June (McOrrie 1990(McOrrie , 1995 and peak C. gigas settlement occurs from November through May (Holliday et al 1993). Nevertheless, because the two species exhibit slightly different salinity and temperature optima for spawning, larval development and settlement (Baradach, Ryther & McLarney 1972;Nell & Gibbs 1986;Nell & Holliday 1988), the relative timing of settlement by the two species will vary from year to year according to climatic conditions. In years where settlement of C. gigas precedes that of S. glomerata, the asymmetry of competitive interactions between the two species may be exacerbated at low elevations, because the exotic species receives an even greater size advantage and may also pre-empt space otherwise available to the native oyster.…”

Summary 1.Trade-offs between competitive ability and tolerance of abiotic stress are widespread in the literature. Thus, condition-specific competition may explain spatial variability in the success of some biological invaders and why, in environments where there is small-scale environmental variability, competitively inferior and superior species can coexist. 2. We tested the hypothesis that differences in abiotic stress alter the outcome of competitive interactions between the native Sydney rock oysters Saccostrea glomerata and exotic Pacific oysters Crassostrea gigas by experimentally testing patterns of intra-and interspecific competition across a tidal elevation gradient of abiotic stress at three sites on the east coast of Australia. 3. At low and mid-intertidal heights, exotic C. gigas were able to rapidly overgrow and smother native S. glomerata , which grew at c . 60% of the exotic's rate. In high intertidal areas, where C. gigas displayed about 80% mortality but similar growth rates to S. glomerata , the native oyster was not affected by the presence of the exotic species. 4. Asymmetrical effects of the exotic species on the native could not be replicated by manipulating densities of conspecifics, confirming that effects at low and mid-intertidal heights were due to interspecific competition. 5. Our results suggest that the more rapid growth of C. gigas than S. glomerata comes at the cost of higher mortality under conditions of abiotic stress. Thus, although C. gigas may rapidly overgrow S. glomerata at low and mid tidal heights, the native oyster will not be competitively excluded by the exotic due to release from competition at high intertidal elevations. 6. The success of trade-offs in explaining spatial variation in the outcome of competitive interactions between C. gigas and S. glomerata strengthen the claim that these may be a useful tool in the quest to produce general predictive models of invasion success.

“…Salinity concentrations in both basins were within levels that Pacific oysters will tolerate, namely 5–55 p.p.t. (Nell & Gibbs 1986), but may have been below levels suitable for Sydney rock oysters, namely 15–50 p.p.t. (Nell & Gibbs 1986).…”

Evaluation trials were undertaken in two evaporation basins filled with saline groundwater to identify finfish and shellfish that have the potential to survive and grow in these conditions. Test animals were reared in replicate culture units in each of two basins filled with saline groundwater located in the Goulburn±Murray Irrigation District (GMID), southeastern Australia. Salinity in basin 2 (9.5±24.6 p.p.t., mean 16.8 p.p.t.) was significantly higher than in basin 1 (8.8±15.2 p.p.t., mean 11.6 p.p.t.). Some differences were observed between the ionic concentrations in the groundwater and sea water (at 10 p.p.t.) and may have affected growth and survival of some species. Survival and growth for oysters (Crassostrea gigas and Saccostrea glomerata) in the basins were low. Shrimps (Penaeus monodon and Marsupenaeus japonicus) did not survive beyond 3 weeks. Of the eight species of fish stocked into the basins, Salmo salar, Macquaria novemaculeata and Acanthopagrus butcheri survived and grew in both basins. Oncorhynchus mykiss did not survive in the low-salinity basin, whereas Bidyanus bidyanus did not survive in the high-salinity basin. These results indicate that some species of fish in particular can be cultured in saline groundwaters within the GMID.
