9th International Conference on Harmful Algal Blooms, 7-11 February 2000, Hobart

Funded Activity Summary

Starting in the mid 1980s, Australia has experienced an increased public
awareness of harmful algal blooms, especially their suspected involvement
in causing fish kills and feared public health risks following consumption
of contaminated seafood products and drinking water supplies. If not
adequately monitored and managed, the economic impacts on Australia's
developing aquaculture industry and on both domestic and export markets
could be devastating. An example of the first problem is the 1989 bloom
event by the golden-brown flagellate Heterosigma akashiwo in Big Glory
Bay, New Zealand, which killed NZ$ 12 million worth of cage-reared chinook
salmon. An example of the second problem is the 1993 New Zealand outbreak
of neurotoxic shellfish poisoning by the dinoflagellate Gymnodinium cf.
breve (NSP; 180 illnesses, no deaths) which led to export losses of NZ $
4.5 million in the first quarter of 1993 and a 25% decrease in domestic
shellfish demand . Similarly, positive test results are now available from
Australian shellfish products for paralytic shellfish poisons (NSW,
TAS,VIC,SA), diarrhetic shellfish poisons (TAS), amnesic shellfish poisons
(VIC) , neurotoxic shellfish poisons (VIC) and cyanobacterial peptide
toxins (WA). While algal biotoxins only in extreme cases lead to human
fatalities, it is the so-called "halo"-effect of bad publicity resulting
from a few human poisonings that can devastate aquaculture industries.
Compared to our neighbour New Zealand, which spends $3.2 M per year in
biotoxin monitoring efforts (most comes from the Ministry of Health, with
industry providing $750,000 per year via an industry levy), Australian
efforts in this area of quality assurance and environmental protection of
aquaculture operations are unsatisfactory.

Objectives:
1. To host a successful international conference dealing with: (1) Ecology and oceanography of harmful algae events; (2) Taxonomy of the causative organisms; (3) Chemistry of the toxins involved; (4) Management of toxic and harmful events; and (5) Pharmacological and epidemiological aspects. The conference will comprise: Keynote lectures, Oral and poster presentations, Round table discussions; Workshops; as well as a Social Programme including excursions to key Tasmanian aquaculture operations. A conference web site on the internet will also be created.
