Yellowfin Tuna

Schools of yellowfin tuna pass through the open water adjacent to North Reef during the northeast monsoon transition months of October and November, chasing baitfish aggregations triggered by upwelling. Sightings are brief but dramatic — dense silver masses of tuna moving at speed through the blue water at the reef's edge. Their presence is a seasonal reminder of Pigeon Island's position within a productive pelagic corridor.
