HABreports: Online Early Warning of Harmful Algal and Biotoxin Risk for the Scottish Shellfish and Finfish Aquaculture Industries

We present an on-line early warning system that is operational in Scottish coastal waters to minimize the risk to humans and aquaculture businesses in terms of the human health and economic impacts of harmful algal blooms (HABs) and their associated biotoxins. The system includes both map and time-series based visualization tools. A ?traffic light? index approach is used to highlight locations at elevated HAB/biotoxin risk. High resolution mathematical modelling of cell advection, in combination with satellite remote sensing, provides early warning of HABs that advect from offshore waters to the coast. Expert interpretation of HAB, biotoxin and environmental data in light of recent and historical trends is used to provide, on a weekly basis, a forecast of the risk from HABs and their biotoxins to allow mitigation measures to be put in place by aquaculture businesses, should a HAB event be imminent.

The online early warning system operational in Scottish coastal waters aims to minimize the risks of harmful algal blooms (HABs) and their biotoxins to human health and aquaculture businesses. The system includes map and time-series based visualization tools and uses a 'traffic light' index approach to highlight locations at elevated risk. Expert interpretation of data, high-resolution mathematical modeling, and satellite remote sensing are used to provide weekly forecasts of HAB risks, allowing aquaculture businesses to implement mitigation measures if a HAB event is imminent.
