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...

Monitoring abalone juvenile abundance following removal of Centrostephanus and translocation

A new system of Abalone recruitment modules (ARMs) have proven to be successful in collecting juvenile abalone in Tasmanian waters. This design was subsequently transferred to the Eastern Zone, Victoria, where IMAS staff and Eastern Zone Abalone Industry Association (EZIZA) members installed ARMs at...

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...
