Can commercial harvest of long-spined sea urchins reduce the impact of urchin grazing on abalone and lobster fisheries?

At low-levels of exploitation, commercial harvesting of long-spined sea urchins was found to prevent increase in urchin density. Adjacent unfished locations experienced an increase in both urchin density and grazed area over the 2014 – 2016 study period. Research sampling of populations...

FRDC-DCCEE: preparing fisheries for climate change: identifying adaptation options for four key fisheries in South Eastern Australia

Over the next century, the marine ecosystems of south-eastern Australia are expected to exhibit some of the largest climate-driven changes in the Southern Hemisphere. The effects of these changes on communities and businesses will depend, in part, on how well fishing industries and resource managers...

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...

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,...

Tactical Research Fund: trial of an industry implemented, spatially discrete eradication/control program for Centrostephanus rodgersii in Tasmania

The long-spined sea urchin, Centrostephanus rodgersii has expanded its distribution southwards from southern New South Wales, through Eastern Victoria, the Bass Strait Islands and down the east coast of Tasmania. In some areas of Tasmania abundance of C. rodgersii has increased substantially, even...

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...

Managing ecosystem interactions across differing environments: building flexibility and risk assurance into environmental management strategies

Summary The overarching aim of this research was to provide an improved understanding of the environmental interactions of Atlantic Salmon farming and to provide recommendations to both government and industry on monitoring and management strategies that are appropriate to the level of risk...
