Stone #fishweirs on the coast of the northernmost tip of Viti Levu, #Fiji’s main island. The area has several stone fish weir clusters, and local tradition suggests the traps date to the 18th century. A focal point for traditional communities who construct and maintain them. #coastalhistory #muSEAum

The weirs were located close to a channel or pass and were most productive from May to November. Currently, few of these original traps are in use due to overfishing and lack of repair. Species such as parrot fish, groupers and other reef fish are taken
