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...
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...
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...
The management of abalone stocks is difficult for many reasons including their high value and the exceptional levels of spatial structuring found in their stocks. In Tasmania, for example, suggestions to change such things as a legal minimum length or introduce a formal harvest strategy to replace...
The Australian abalone industry identified a clear need to conduct research into this area to gain knowledge, but also because there has never been such a comprehensive investigation into the Australian abalone industry, its markets, global production, abalone consumption and consumption trends and...
The Australian abalone industry identified a clear need to continue with the work done by David McKinna and the investigation into the Australian abalone industry, its markets, global production, abalone consumption and consumption trends and Australia’s position in the market....
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...
This project is a revision of FRDC Project 2001/033 which was originally titled Enhancement of the NSW blacklip abalone fishery using hatchery produced seed. The original project included a significant cash contribution from the NSW Abalone Fishing Industry but unfortunately after FRDC approved the...
