Need

The role of creating an environment for sustainable aquaculture development throughout Australia is critical in reaching the industries primary goal of doubling the value of the Australian seafood industry to $4 billion by 2017 and generating more than 2,800 new jobs in rural and regional areas. Enhancing a regions capacity to undertake sustainable marine aquaculture development from an initial policy driven perspective brings with it a heightened level of investor confidence and regional based skills development and acquisition.

A recent report undertaken by the Australian Productivity Commission (2004) found amongst others that:

• Aquaculture production is subject to an unnecessarily complex array of legislation and agencies.
• State aquaculture and/or fisheries legislation have multiple objectives and these are not always clearly defined.
• State government departments primarily responsible for aquaculture regulatory arrangements often have potentially conflicting
of policy development, implementation of regulation, industry promotion and development, and research.
• New South Wales, Queensland and Western Australia have made limited progress with marine aquaculture planning. This may constrain marine aquaculture, or result in ad hoc approvals for individual sites, and conflicts over resource use.

The Queensland Department of Primary Industries and Fisheries have identified a number of areas that have to be addressed in order to develop a sustainable aquaculture industry in Queensland, two of these are Policy and Legislation as well as Aquaculture planning;

There is also an identified gap in aquaculture planning within the Great Barrier Reef Marine Park Authority. The Great Barrier Reef Marine Park Authorities own Position Statement on Aquaculture Development within the Great Barrier Reef Marine Park (2004) states that ‘Guidelines for the assessment of applications to conduct intensive aquaculture in the GBRMPA need to be developed’.

Need

The Sydney Rock Oyster (SRO) aquaculture industry is the largest and oldest aquaculture industry in NSW with annual revenue of approximately A$35 million (I&I NSW 2011). SRO breeding was initiated in 1990 through mass selection aiming to develop faster growing, winter mortality resistant lines (Nell et al. 2000). After five generations the average time to market size reduced by more than 12 months (Nell and Perkins 2005) and disease resistant lines were available. In 2004, the first progeny from 5th generation fast growing lines were distributed to oyster farmers in NSW. In comparison to wild-caught oysters, these stocks demonstrated clear differences in reproductive behaviour, which affected marketability in various estuaries throughout NSW (O’Connor and Dove 2011). While industry demand for selectively bred SRO remains strong (2011/2012 spat sales will exceed 20,000,000 and will form the basis of more than 20% of total production), these changes pose both challenges and opportunities for the entire SRO production cycle from the hatchery, where oysters in “ripe” reproductive condition are required for spawning, through to market where reproductive condition is a major determinant in “saleability”.

With the progression of the SRO breeding program from 3 “base” mass selected lines to 120 pair-mated families, investigation into the biology behind the altered condition index of selectively bred oysters is of great importance. Initially, there is a fundamental need for reproductive concurrency among lines to allow breeding. Secondly, genetic variability in reproductive condition offers the opportunity to manage marketability through the selection of lines whose characteristics suit market requirements.
