Hawaiians are the only Polynesians known to harness the ocean’s bounty using brackish-water ponds near the ocean for stocking and harvesting fish. The system allowed Hawaiians to control algae, a major food source for fish.

During ancient times when the ponds were controlled by the ali‘i (chiefs), most of the fish was reserved for their consumption.
