Integrating multi-stage interventions for harmful algal blooms effective management

Area of Science:

• Environmental Science
• Ecology
• Aquatic Management

Background:

• Harmful algal blooms (HABs) are a growing global threat to ecosystems, economies, and public health, exacerbated by water eutrophication.
• Current HAB control methods often focus on emergency responses, ignoring the algal life cycle, leading to inefficiency and ecological concerns.

Purpose of the Study:

• To propose a novel, life-cycle-based precision management system for harmful algal blooms (HABs).
• To shift HAB management from reactive, single-method approaches to a proactive, integrated framework.

Main Methods:

• Reviewing current HAB control strategies and their limitations.
• Proposing a four-stage life-cycle model (dormancy, germination, growth, outbreak) for HAB management.
• Integrating monitoring indicators and control portfolios with stage-specific interventions.

Main Results:

• Traditional HAB management is often inefficient due to a lack of life-cycle consideration.
• A precision management system requires accurate stage identification, monitoring-informed thresholds, and integrated control technologies.

Conclusions:

• Effective HAB control necessitates a transition to a life-cycle-based precision management system.
• Future research should focus on intelligent monitoring for stage identification and synergistic effects of control methods to advance precision HAB control.
