Indigenous ecological knowledge and chemical signaling networks reveal systemic vulnerabilities in global HAB hotspots—challenging industrial ocean monitoring paradigms

The voices of coastal fishing communities in regions like the Gulf of Mexico, the Philippines, and West Africa—where HABs have devastating impacts on livelihoods—are absent from the current narrative. These communities, often marginalized by industrial fishing and climate policies, have developed their own adaptive strategies for navigating HABs, such as shifting fishing grounds or using traditional detoxification methods for shellfish. Their perspectives are critical for understanding the human dimensions of HABs, including how cultural practices, economic dependencies, and historical injustices shape vulnerability. The exclusion of these voices perpetuates a top-down approach to marine management that ignores the lived realities of those most affected by HABs, reinforcing power imbalances in global ocean governance.
The discovery of predator chemical cues as an early-warning system for HABs is not merely a scientific breakthrough but a revelation of the ocean’s inherent resilience—a system that has been ignored, exploited, and now offers a path to reconciliation.
For centuries, Indigenous communities and marine organisms alike have relied on these cues to navigate and adapt to environmental changes, yet Western science has treated them as secondary or irrelevant until now. The structural causes of HABs—such as industrial nutrient runoff and colonial-era marine governance failures—have obscured the potential of this knowledge, reinforcing cycles of epistemic injustice where marginalized voices are silenced. By integrating Indigenous ecological knowledge with modern technology, we can shift from reactive to proactive marine management, but this requires dismantling the power structures that have historically excluded these communities from decision-making. The trickster energy of the ocean’s chemical signals challenges us to see beyond the solemnity of 'discovery' narratives and embrace a future where science, culture, and ecology coexist as co-equal partners in marine conservation.
