Tactical Research Fund: a reporting framework for ecosystem based assessment of Australian prawn trawl fisheries
There is a growing need to establish fishing industries as environmentally sustainable within Australia and internationally. The needs stems from both an economic marketing aspect and a growing community expectation. It is also important for fishing industries to understand that they contribute to marine impacts on a broader ecological scale. Whilst the principles of Ecosystem Based Fishery Management (EBFM) have been established for over a decade, it is only in recent years that EBFM frameworks have begun to be developed and applied by Government agencies (e.g. Fletcher et al 2010, West Coast Bioregion of Western Australia).
The environmental impacts of benthic trawl fisheries require greater attention than most other fishing methodologies, primarily due to their impact on the benthic environment, by-catch species and associated communities. As a critical impactor on marine bioregions, it is important that future ecological research for benthic trawl fisheries is prioritised and conducted in a manner that fits within a broader EBFM framework.
Concomitantly, there is an increasing interest from fishing industries to seek third-party certification of environmental sustainability for eco-labelling of their products and subsequent market advantage. These Program's require fisheries to meet standards that are often higher than the levels required by the Commonwealth Government to meet conditions of the EPBC Act. Although such accreditations are accompanied by substantial documentation of management practices, it is difficult for non-accrediated fisheries to benchmark themselves against accredited "best practice" industries.
This project aims to develop a reporting framework for environmental assessment of prawn trawl fisheries in Australia. By using the Marine Stewardship Certification accredited Spencer Gulf Prawn Trawl Fishery as a case study, the report will provide other Australian prawn trawl fisheries 1) a benchmark of third party accredited environmental management, and 2) a tool for prioritising and conducting their own ecological research within an EBFM framework.

Tactical Research Fund: National assessment of the incidental catch of seabirds in trawl, gillnet and purse-seine fisheries - draft final report review
Australia, as a Member State of the Food and Agriculture Organization of the United Nations (FAO) endorsed the FAO International Plan of Action for Reducing Incidental Catch of Seabirds in Longline Fisheries in 1999. In 2009, FAO Member States agreed to include trawl and gillnet fisheries in the FAO guidelines for best practices to reduce incidental catch of seabirds in capture fisheries. As a result, Australia agreed to carry out an assessment of its longline, trawl and gillnet fisheries to determine if a seabird bycatch problem exists and adopt a National Plan of Action for Reducing Incidental Catch of Seabirds in Fisheries. While FAO has only extended its guidelines to gillnet and trawl fisheries, the proposed project will also investigate seabird interactions with purse-seine vessels as a proactive step in developing a comprehensive plan of action for reducing the incidental catch of seabirds during fishing operations.
An assessment of seabird interactions in longline fisheries was completed in 2008, however a national assessment of seabird mortality from trawl, gillnet and purse-seine fisheries in Australian waters is still to be conducted. Mortality of seabirds associated with trawl, gillnet and purse-seine fisheries is less documented but an increasingly recognised issue, especially in trawl fisheries where seabirds can get caught on the warp lines and drown, collide with other vessel cables or become entangled in the mesh of nets at the sea surface. In gillnet fisheries, seabirds can become entangled with the mesh or vessel cables while in purse-seine fisheries seabird may become entangled in the mesh of nets. The extent of such interactions is unknown and an assessment is required which will be used to inform the development of a National Plan of Action for Reducing Incidental Catch of Seabirds in Fisheries.
Tactical Research Fund: Reducing the impact of discarded recreational fishing tackle on coastal seabirds
This proposal will address the FRDC Recfishing Research priority area "Assessing the impact of recreational fishing methods on conservation values of aquatic habitats" as announced in the 2012 Annual Competitive Round Call for Expressions Of Interest. After making inquiries with seabird rescue organisations, it has become apparent that seabird entanglements in discarded fishing tackle is of major concern. Australia Zoo Wildlife Hospital report that their rescue unit responded to approximately 300 calls for bird entanglements in discarded fishing tackle in 2011 (to August 1). Further, the Rescue Hotline of Pelican and Seabird Rescue Inc. have received approximately 400 calls in 2011 (to the time of writing - 10/9/2011). These figures are unacceptable and measures need to be taken to decrease the incidence of seabird interactions with discarded recreational fishing tackle. The injuries that result from these interactions are often catastrophic, with a high proportion of entangled animals being euthanised. Healthy Waterways has produced a provocative poster, attached, depicting a pair of budgerigars surrounded by fishing line and hooks. Such negative stereotypes need to be addressed and, as such, there is a need to educate recreational fishers as to the consequences of the careless discarding of fishing tackle. This subject was recently highlighted in a Queensland recreational fishing publication, Queensland Fishing Monthly (see attachment). Both recreational fishing representative groups, Sunfish and Ecofishers, have expressed concern regarding this issue. A fifteen minute search at a secluded recreational fishing location in the northern suburbs of Brisbane by two people resulted in the collection of the fishing tackle pictured in the attachment (13/09/2011 - Tingalpa Creek). Although this could be construed as an environmental problem and beyond the purview of FRDC, it certainly reflects poorly on recreational fishers and, as such, an extension/educational project would help alleviate the problems highlighted in this proposal.

Tactical Research Fund - Aquatic Animal Health Subprogram: determining the susceptibility of Australian species of prawns to infectious myonecrosis
Australian prawn production at around 22 kilotonnes is valued in excess of $250 million. Clearly, the prawn fishery is an important natural resource for Australia that is also the basis for a significant export industry. In addition, prawn aquaculture is a significant industry in northern Australia and accounts for around 14% of the total volume of Australian prawn production. Infectious myonecrosis is a viral disease that has caused significant disease outbreaks and mortalities in farmed Penaeus vannamei in Brazil and South-East Asia, including Indonesia. While P. vannamei is considered the principal host, experimental infection of P. stylirostris (Pacific blue shrimp) and P. monodon (black tiger shrimp) has been reported. The susceptibility of other shrimp/prawn species is unknown. Information on the susceptibility of prawn species important to Australia, including banana prawns (Fenneropenaeus merguiensis), brown tiger prawns (P. esculentus) is lacking. This project would provide information on the susceptibility of two important species of Australian prawns to exotic IMNV. Such information is important to policy-makers, regulators and primary producers with respect to relevant biosecurity issues at all levels of government.

Tactical Research Fund - Aquatic Animal Health Subprogram: Disease risk assessment for abalone stock enhancement program
Abalone stock enhancement remains one of the few viable alternatives for increasing the profitability and biomass of a fishery without compromising the current fishery in terms of access or allowable catches. Economically viable stock enhancement could provide the fishery with stock numbers towards virgin levels, thus increasing catch rates and ultimately economic efficiency and profitability. However, there is a need for a project to develop the R&D that will create a commercially viable stock enhancement industry. This is the subject of a current Seafood CRC project (2010/784 - Commercialisation of abalone stock enhancement).
Prior to the commercialisation the industry wants to understand the biosecurity risks of the larger scale stock enhancement project; in other words to weigh up the potential economic gains against biosecurity risks. The recent AVG outbreak in Tasmania highlighted the requirement for industry to be vigilant regarding potential disease vectors.
In order to protect the valuable abalone industry from potential biosecurity threats, there is a need to undertake a risk assessment to quantify raw and residual risks associated with commercialization of abalone stock enhancement. Although being carried out in WA, this risk assessment has national significance to the abalone industry.
