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...
(1) To enable assessment reporting of trends in biomass and egg production by depth.
(2) To evaluate separate deep-water quota to increase yield and egg production.
(3) To evaluate regional size limits in Tasmania for increase in yield and egg production.
(4) To conduct field...
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...
Outcomes achieved to date
The outputs from this second phase of the project have led to the following outcomes:
1. A refined puerulus collector design that:
• Collects puerulus as effectively as traditional diver-serviced inshore collector systems
• Collects puerulus...
Translocation involves the shifting of undersize rock lobsters to new areas to increase productivity and/or quality of product. We modelled the translocation of rock lobsters from four original sites to four release sites with a range of growth rates.
Most model scenarios led to increases in...
