New sensors capture warning signs before fish deaths in Lake Victoria
Researchers from King's College London successfully used water-quality sensors to detect oxygen depletion in Lake Victoria, providing early warnings before fish deaths occurred. The project integrates AI and satellite data to help local aquaculture farmers mitigate environmental hazards.

Add as preferred source Credit: King's College London Researchers from King's College London recorded the warning signs of a major low-oxygen event in Lake Victoria just hours before fish deaths were reported by local communities, demonstrating why earlier warning systems are urgently needed.
The discovery came only days after researchers deployed pilot water-quality sensors at aquaculture sites near Dunga Beach, Kisumu, as part of a project to develop new tools for monitoring and anticipating water-quality hazards. The sensors recorded dissolved oxygen levels falling to almost zero before reports emerged of fish deaths in the same area.
