We aim to define through a combination of laboratory culture exposure and live cage bioassay experiments the minimum cell concentrations of harmful microalgae (Karenia, Heterosigma, Noctiluca, Chaetoceros) that can cause salmonid mortalities or are a factor in compromising fish health or reducing fish farm productivity. The diagnostic pathology and fish behaviour caused by different harmful algal taxa will be carefully documented to assist fish health inspectors in the routine diagnosis of algal toxicosis ot compromised fish health. Ultimately, this information will be integrated into a risk assessment strategy for the Tasmanian salmonid industry to manage fish stocks during times of harmful algal bloom events.

我们的目标是通过实验室培养物暴露和活体网箱生物测定实验相结合，确定有害微藻（凯伦藻、异形藻、夜光藻、角毛藻）的最低细胞浓度，这些藻类可能导致鲑鱼死亡，或者是损害鱼类健康或降低养鱼场生产力的一个因素。由不同有害藻类引起的诊断病理学和鱼类行为将被仔细记录，以协助鱼类卫生检查员对藻类中毒或受损鱼类健康进行常规诊断。最终，这些信息将被纳入塔斯马尼亚鲑鱼产业的风险评估策略中，以便在有害藻华事件期间管理鱼类种群。
