Need

The 2000/01 National Recreational and Indigenous Fishing Survey (NRIFS) yielded the first comprehensive assessment of recreational fishing in Australia. Core components were a telephone-based screening survey of households followed by a phone/diary survey in which fishing and expenditure was monitored.

From a methodological perspective, exceptionally high survey response rates, a comprehensive approach to non-response calibration and representation are features that have been recognised internationally as benchmarks for such surveys. However, the complexity of the NRIFS and sheer quantity of data collected meant that analysis was not straightforward and simple statistical approaches were not available.

Since the NRIFS, several jurisdictions have identified the need to provide on-going state-wide and regional information about their recreational fisheries, with the NRIFS methodology seen as cost effective in providing such information. For instance, Tasmania and SA will be conducting state-wide surveys in 2007/08 and Victoria and WA are undertaking regional surveys using the methodology.

While the efficacy of the phone/diary methodology in collecting detailed and robust data has been established, options for data analysis need to be developed and more fully integrated. Specifically, analytical routines need to interface directly with the databases and be flexible enough to enable a range of queries to be run efficiently and be repeatable. The development of an analytical module would represent a significant advancement in the provision of recreational data and will have immediate and on-going application in a number of jurisdictions. This project directly addresses AFMF and national recreational R&D priorities relating to assessment of non-commercial fishery impacts.

Objectives

1. Review and document statistical procedures for analysing large-scale phone/diary recreational survey data
2. Develop an integrated and flexible data analysis module for phone/diary recreational survey data
3. Undertake a re-analysis of key NRIFS data outputs
4. Roll-out and demonstrate the analysis module to potential users

Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: development of selective enrichment culture-polymerase chain reaction (SEC-PCR) for the detection of bacterial pathogens in covertly infected farmed salmonid fish

Bacterial disease is a major cause of stock loss in aquaculture. The severity of infection may range from acute to chronic through to benign. This latter condition, termed covert infection, is insidious, as fish may appear to be outwardly healthy but during periods of stress, these carriers may...

Reassessment of intertidal macroalgal communities near to and distant from salmon farms and an evaluation of using drones to survey macroalgal distribution

The salmon farming industry has significantly expanded in South-eastern Tasmanian both in production and in number and location of farms. Along with this expansion has been an increasing concern from the general community about the effects of salmon farms on the environment. This includes a reported...
