Pulau Ubin’s mangrove ecosystem supports a healthy fishery around the island. 80% of all wild juvenile fishes spend their childhood inside Pulau Ubin’s extensive mangrove system. The daily changing tides provide a constant source of food and the mangrove roots provide protection from the predators.
When the fishes get too big for the mangrove roots to protect them, they venture out of the mangrove into the waters around the island. With a constant supply of fish from the mangrove, fishing is always good around Pulau Ubin.
