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...
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...
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...
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,...
The CRC has developed the Future Harvest theme business plan to deliver the following outcomes:
Fisheries management delivering maximum benefit from the resource while maintaining stocks above sustainability indicators
Novel management strategies in place which increase economic yield from...
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...
