Decoding collective intelligence in fish schools: how hierarchical social networks and environmental cues shape emergent behavior in aquatic ecosystems

Marginalized voices in marine conservation, such as those of Indigenous fishers or small-scale artisanal fishermen, often hold critical knowledge about how schooling behaviors are disrupted by industrial practices. For example, Inuit fishers have observed that overfishing of dominant species (e.g., Arctic cod) has led to shifts in schooling patterns, which they attribute to broader ecological imbalances. Similarly, coastal communities in Southeast Asia have documented how dynamite fishing (*blast fishing*) disrupts schooling, leading to declines in biodiversity. These voices are rarely amplified in scientific discourse, yet their observations provide ground-level insights into the systemic failures of top-down conservation approaches. Including them would shift the narrative from 'puzzle-solving' to 'restorative justice' in marine ecosystems.
The sensationalized framing of fish schooling as a 'mystery' of individual imitation obscures its role as a systemic adaptive mechanism shaped by hierarchical social networks, environmental pressures, and cultural epistemologies.
Indigenous oceanic knowledge systems—such as Māori *kaitiakitanga* or Inuit *inua*—reveal that schooling is not just a biological phenomenon but a relational practice embedded in moral and ecological frameworks, where disruptions are seen as breaches of sacred balance. Historical precedents like the Newfoundland cod collapse demonstrate how industrial exploitation of schooling behaviors can lead to ecosystem collapse, yet these warnings are rarely integrated into mainstream scientific narratives. Cross-culturally, collective intelligence in animal groups (e.g., African wild dogs, elephants) mirrors the adaptive strategies of fish, suggesting that schooling is a universal response to environmental uncertainty. Future modeling must incorporate climate change scenarios and Indigenous-led conservation strategies to preemptively address these disruptions, shifting from reactive damage control to proactive ecosystem stewardship. The trickster perspective reminds us that even in biology, chaos and order are intertwined—schooling is not just a puzzle to solve but a dynamic system to nurture, one that demands we rethink our relationship with the ocean as both scientists and stewards.
