| The paper presents a complex framework to analyse spatially and seasonally heterogenous fisheries. Typologies based on multivariate analysis have been applied on multi-species fisheries to identify patterns in fishing effort and subsequent impacts on various species. Although the Tasmanian rock lobster fishery is a single species fishery, it displays highly variable spatial and seasonal patterns of fishing effort. Rock lobster is a stationary species, so the stock of rock lobster is heterogeneously distributed along the Tasmanian coast depending on local removal from catch. The various perturbations undergone by the stock for the past decade, (overexploitation, introduction of individual transferable quotas (ITQs), climate change) led to the reorganisation... |
