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...

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...

Patterns of interaction between habitat and oceanographic variables affecting the connectivity and productivity of invertebrate fisheries

A better understanding of the links between benthic habitat, oceanography, and fisheries productivity is a major priority of the Blacklip Abalone, Haliotis rubra, and Southern Rock Lobster, Jasus edwardsii, industries to improve sustainable management of these important natural resources. This...
