Maximise yield or minimise risk in the Blacklip Abalone fishery: using biological data to direct harvest strategies

The primary goal of this research was to identify attributes of the seasonal biology of Blacklip Abalone (Haliotis rubra; hereafter referred to as Blacklip) that may be beneficial for optimising fishing strategies. The optimum months to harvest Blacklip to maximise yield were identified using a...

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...

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...

Population genomic assessment of Australian Blacklip Abalone for abalone viral ganglioneuritis (AVG) resistance

Abalone viral ganglioneuritis (AVG) remains a significant threat to the economic viability and stability of the Abalone industry in south-eastern Australia. Consequently, there is an urgent need for strategic research aimed at determining the likely vulnerability of fisheries to future AVG outbreaks...

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...
