Today's talk
  • Background
  • Objectives
  • Risk assessment results
  • Framework template
  • Expected outcomes
tasmanian response
Tasmanian Response
  • Prohibition on Victorian abalone vessels operation in Tasmanian waters.
  • Ganglioneuritis listed as a notifiable disease in Tasmania.
  • Abalone product of non-Tasmanian origin prohibited in Tasmanian waters February 2007.
  • Moratorium on new abalone farms and flow through processor facilities.
  • Closure of Bass Strait zone March 2007.
slide4
Impact on Tasmania
  • Restrictions on recreational and commercial fishing activities in Bass Strait and King Island. including requirement to land all commercial abalone from around King Island on King Island.
  • No processing King Island abalone in premises on mainland Tasmania that discharge into the marine environment.
  • Prohibition on possession of abalone and rock lobster for recreational fishers in certain waters with all recreational abalone and rock lobster to be landed in Tasmania
objectives biosecurity policy
Objectives: Biosecurity Policy
  • Tasmania’s biosecurity policy objective is “to protect and enhance Tasmania’s biosecurity status for the benefit of Tasmania’s industries, environment and public well-being, health, amenity, and safety.”
  • Two key elements are:
    • -Appropriate Level of Protection (ALOP)
    • -Shared responsibilities.
  • Tasmania’s ALOP is a high or very conservative level of protection aimed at reducing risk to very low levels, while not based on a zero risk approach.
risk assessment process
Risk Assessment Process
  • Delivered strategically identified risks across all fishing and farming sectors
  • Used the precautionary principle
  • All risks above very low have been integrated into the Abalone Biosecurity Framework
biosecurity risk of wild sector
Biosecurity Risk of Wild Sector
  • High Risks
    • Emergency Response for the Abalone Wild Fishing Sector
    • Movements of live animals from the wild into live holding facilities within Tasmania
    • Movements of live animals from the wild into processing facilities within Tasmania
    • Movement of equipment and personnel from Victoria or other state to Tasmanian waters
    • Movement of equipment and personnel by commercial divers around the State
biosecurity risk of wild sector8
Biosecurity Risk of Wild Sector
  • Health surveillance program for the wild and farmed sector
  • Moderate Risks
    • Collection of live animals from the wild for farm brood stock.
    • Unloading of abalone for processor pick up where abalone is repacked on wharf or boat ramp
biosecurity risk of the processing sector
Biosecurity Risk of the Processing Sector
  • Extreme Risk
    • Processing of whole interstate abalone
  • High Risk
    • Sale of abalone viscera as bait to commercial and recreational fishers.
    • Discharge of water from processor facilities into the marine environment
biosecurity risk of the processing sector10
Biosecurity Risk of the Processing Sector
  • Moderate risk
    • Discharge of water from live holding facilities into the marine environment.
    • Inappropriate disposal of waste materials such as viscera, and shell into the marine environment.
    • Movements of contaminated equipment from processing facilities to divers.
    • Movement of live animals to other processing facilities (ie between processors).
    • Processing of partially processed interstate abalone for canning purposes
biosecurity risk of farmed sector
Biosecurity Risk of Farmed Sector
  • High Risks
    • Movements of abalone for purposes of emergency harvest from aquaculture facilities into processing facilities.
    • Movement of live animals to ocean based marine farms
biosecurity risk of farmed sector12
Biosecurity Risk of Farmed Sector
  • Moderate Risks
    • Discharge of water from farms into the marine environment
    • Movements of live animals from the wild into facilities as brood stock.
    • Movement of live animals to other land based aquaculture facilities.
    • Movements of live animals from aquaculture facilities into processing facilities.
biosecurity risk of farmed sector13
Biosecurity Risk of Farmed Sector
  • Low risks
    • Movement of equipment and personnel to other land based aquaculture facilities.
    • Unintentional transfer of live animals from farm to the marine environment via feral or escaped stock
    • Inappropriate disposal of shells and waste material into the marine environment
common risks between sectors
Common Risks Between Sectors
  • Need for an emergency response plan
  • Movement of animals interstate and intrastate
  • Translocation of equipment (including boats, farm equipment, fish bins)
  • Discharge of waste water from all sectors
  • Disposal of animal waste from all sectors
  • Biosecurity surveillance program

Emergency Response Plan

emergency response
Emergency response
  • ISOLATION of any outbreak
    • Management controls on movements
  • ZONING (Biosecurity regions)
  • SURVEILLANCE
    • Passive & Active
  • ERRADICATION
expected outputs
Expected Outputs
  • A biosecurity strategy to minimise risk in the abalone sector;
  • Documented risk assessment;
  • Documented and agreed performance requirements in the commercial wild harvest fishery, recreational fishery and marine framing sectors;
  • High level protection of abalone stocks to disease outbreak;
  • Emergency Disease Response plan “at the ready” should a disease outbreak occur.
