Workshop 3.
Mitigation of harmful algal blooms: Novel approaches to a
decades long problem affecting the viability of natural and
aquaculture fisheries
Co-Convenors:
Ichiro Imai (Japan)
Changkyu Lee (Korea)
Charles Trick (Canada)
Mark Wells (USA)
Invited Speaker:
David Kidwell (National Ocean Service, NOAA, USA)
Harmful Algal Blooms (HABs) have substantial economic, societal, and human health impacts in coastal waters
worldwide, from equatorial to high latitude environments. Our increasing reliance on the economic services
of coastal waters is threatened by the apparent increasing frequency and severity of HABs globally. Currently,
clay dispersal in Korean waters is the only pragmatic operational program for mitigating HAB effects on coastal
aquaculture operations. The trade-off, namely smothering of benthos with rapid sedimentation of clays, is not
acceptable in many nations, leaving them with few if any mitigation strategies. This workshop will open with
presentations on current rules for testing and implementing mitigation strategies in PICES member countries to
set the stage for considering HAB mitigation. Participants then will deliberate on novel physical, chemical, and
biological control strategies and research paths that have potential for minimizing or eliminating HAB effects
without significant coincident impacts on ecosystem health. The aim of the workshop is to develop ndependent
evaluation of mitigation strategies that are effective, transformative and sustainable for individual PICES member
countries, and to provide a framework to advance the scientific collaborations and funding strategies to move
mitigation research into the 20th century.
