Prawn trawl fisheries are under increasing public and legislative pressure to manage their bycatch sustainably. Although this is now explicit in the fisheries management acts and the new Environment Protection and Biodiversity Conservation Act, there is little information on which to base sound...
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...
To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4...
In studies of blacklip abalone (Haliotis rubra) in Tasmania conducted during 1983 to 1987, Jeremy Prince and his research team made several important findings concerning the biology and fishery management of this species. These include:
Rate of deposition of growth layers in the shell is...
