Need

1 - Recreatiopnal Fishing - As identified at the 2012 Recreational Fishing Conference, the vast majority of recreational fishing is inshore. The Conference agreed that habitat protection and repair was one of its four priorities.
RESPONSE- This project spports this priority with the objective of collecting and disseminating in clear and unambiguous terms the loss of inshore productivity due to habitat decline and thence the opportunity for productivity improvement with habitat repair.

2 - Aquaculture - A recent FRDC project developing an Oyster Portal for the oyster industry has clearly identified the decline in Sydney Rock production, much of which can be directly attributed to habitat loss/ net primary productivity decline.
RESPONSE - SRO will be included as one of the indicator fisheries. Growing technology has improved, demand for product is high but production continues to decline.

3 - Commercial Fishing - The Coorong fishery, the prawn fisheries and the barramundi fishery have all been interacting with the PI seeking repair of inshore productivity. All have specific areas of habitat repair and legitimate proposals - eg Burdekin floodplain - over 1500 bunds prohibiting barramundi accessing previous estuarine to freshwater systems; eg Coorong- proposals to maximise the benefits of the increased fresh water in the Murray.
RESPONSE - barramundi, school prawns and coorong fishery will all be case studies

4 - Investor Interest - the Australian Government is keen to invest its Biodiversity Fund in major repair works to theAustralian landscape.
RESPONSE - The companion FRDC funded Business case for habitat repair will suggest a major program of about $300M, including about $10M for further research. This small investment will collate and promate summary facts and figures on the productivity declinne in Australia's estuary fisheries and therefore the benefits of inshore habitat repair.

Objectives

1. To quantify the decline in productivity within tropical estuarine to freshwater systems due to habitat loss and estimate the productivity opportunities of repair
2. To quantify the decline in productivity within Australia's subtropical and temperate east coast major floodplain dominated estuaries due to habitat loss and estimate the productivity opportunities of repair
3. To quantify the decline in productivity within the lower lakes and Coorong, including hypothesising on flow ons to recruitment within Victorian southern estuary systems due to the barrages and overall loss of connectivity and estimate the productivity opportunities of repair in connectivity and freshwater - marine mixing in the Coorong
