Assessing the risk to aquaculture from harmful algal blooms (HABs)
Modelling and prediction of harmful algal events and the potential environmental drivers that lead to their likelihood, duration and intensity.
Marine organisms are an important food resource for humans. Aquaculture has become a consolidated food resource worldwide, the production from which has overtaken the traditional fisheries.
The presence, or increased production, of certain species of phytoplankton are a threat for human and animal health. Non-toxic species can also present a risk through negative impacts on organism physiology, such as damage to organ structures and creation of low oxygen environments. Such phytoplankton mediated harm is generally referred to “Harmful algal blooms” (HABs). These events having generated substantial economic losses for aquaculture through farmed fish kills and human food poisoning (often via “shellfish poisoning”). The presence, duration and intensity of a HAB event is generally related to environmental and hydrographic conditions. Modelling of these events and the analysis of potential drivers is therefore an efficient tool for the prediction of HABs. Models can provide information regarding the harmful event likelihood, duration and intensity, allowing for enhanced predictability and risk evaluation.
This research aims to identify the association strength of species producers of toxins, biotoxins and the potential environmental drivers. A regional analysis considering these factors will enhance the understanding of risk distribution throughout Scotland. Such research is crucial to safeguard the food security of marine products.
