Application of molecular genetics to the Australian abalone fisheries: forensic protocols for species identification and blacklip stock structure

Of the nineteen abalone (Haliotidae) species recognised in Australian waters (Geiger 1999), ten are endemic and two dominate the commercial, recreational and illegal harvests in southern States: the blacklip abalone Haliotis rubra Leach and the greenlip abalone H. laevigata Donovan. A third species,...

Establishment of the long-spined sea urchin (Centrostephanus rodgersii) in Tasmania: a first assessment of the threat to abalone and rock lobster fisheries

The pattern of distribution of the long-spined sea urchin Centrostephanus rodgersii over ca. 40 y in the Kent group, Bass St., suggests initial establishment in the mid 1960s with subsequent expansion of populations to its current status as the dominant invertebrate on shallow subtidal rocky reef....

Implementing a spatial assessment and decision process to improve fishery management outcomes using geo-referenced diver data

Fishing activity was captured across 53,852 one Hectare hex grid cells across Tasmania. A total of 113,164 diving hours were recorded across 125,536 individual fishing events (Table 1). Between 2012 and 2016, the Tasmanian Geo-Fishery Dependent Data (GFDD) program captured between 85 % and 90 % of...

Rebuilding Ecosystem Resilience: assessment of management options to minimise formation of ‘barrens’ habitat by the long-spined sea urchin (Centrostephanus rodgersii) in Tasmania

By overgrazing seaweeds and sessile invertebrates, essentially back to bare rock, the advent of the long‐spined sea urchin Centrostephanus rodgersii in eastern Tasmanian waters poses a significant threat to the integrity, productivity and biodiversity of shallow (<40 m) rocky reef systems and the...

Seafood CRC: Factors limiting resilience and recovery of fished abalone populations

The aims of this project were to: Determine the efficacy of translocation of mature abalone for stock rebuilding Identify key ecological processes that limit stock recovery Quantify the scale of 'spillover' from translocated populations Cost-benefit analysis of rehabilitated...

Evaluating the effectiveness of marine protected areas as a fisheries management tool

Marine Protected Areas (MPAs) are being proclaimed around the world with the stated primary purposes of enhancing fisheries stocks and/or conserving marine biodiversity. In Australia, in response to a joint State/Commonwealth agreement to establish a National Representative System of MPAs (NRSMPA)...
