Tactical Research Fund: a reporting framework for ecosystem based assessment of Australian prawn trawl 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.
Final report
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.
