Abstract

The overarching aim of this dissertation was to augment emerging areas of
research on human dimensions of recreational fisheries through
socioeconomic studies of Tasmanian game fishers. A secondary objective was
to develop an advanced understanding of Tasmanian game fishers in order to
inform the management of the fishery. Largely quantitative socioeconomic
data were collected through two mail questionnaires, a telephone administered
diary survey and a 'supplementary' telephone survey. The study specifically
addressed four areas of research. First, heterogeneity among fishers was
explored according to anglers' levels of recreational specialisation by
developing an index measuring three specialisation sub-dimensions —
behaviour, commitment and skills and knowledge. Three specialisation groups
were identified using cluster analysis and compared using standard statistical
techniques. Anglers' levels of specialisation were significantly related to
mode of fishery access, income, fishing club membership, species preference,
conservation orientation, activity-specific and activity-general motivations,
attitudes to catching large/trophy fish and attitudes to catching particular types
of fish. Second, socioeconomic characteristics were compared between private
boat and charter boat fishers using standard statistical techniques. Applying
specialisation results as a 'filter', significant differences between the two
groups were classified as either specialisation-mediated or specialisation-independent.
Included in the former were income and fishing club
membership; the latter consisted of age, frequency of fishing with family
based groups, activity-general motivations, attitudes to catching large fish and
many fish, and attitudes to management. Angling groups also differed
according to time spent on fishing trips, educational and employment status,
catch history and non-game fishing activity; however, no reference to
specialisation was determined. Third, building on the work of Sutton (2001),
the effects of personal and situational variables on voluntary fish release
behaviour were explored using logistic regression analyses. For private and
charter boat fishers, the odds of voluntarily releasing a fish were positively
related to the skills and knowledge dimension of specialisation, the number of
fish caught on a trip and prior fishing activity during a fishing season. For
private boat fishers, significant predictors included avidity, attitudes to
catching fish and tournament participation. Situational variables had a higher
predictive capacity than personal variables. Fourth, an iterative bidding
contingent valuation methodology was employed to determine whether
resource valuation ascribed by private boat fishers was influenced by harvest
orientation and/or by sub-dimensions of specialisation. Using multiple linear
regression models, fishers' willingness to pay (above what they had already
spent) for seasonal fishery access was significantly related to avidity, income,
the number of fish caught during the season and fishers' levels of agreement
with promoting catch and release fishing. Finally, various implications of the
results for the management of the fisheries were discussed, and future
research needs were identified.
