On Makogai Island ( 30 km to the north east of Levuka) is a breeding station
for giant clams. Some clam species are threatened in Fiji due to over
so there are successful efforts undertaken by Fiji Fisheries to breed and
reintroduce clams to Fiji reefs.
Process: parent clams are set in holding tanks, spawning will be
introduced with a hormone injection, after a few days tiny clams
settle in the bottom of tank, transfer into larger tanks later then
into the ocean to repopulate the reefs.
Clams are injected with Serotonin which will release pheromones and cause
spawning in clams within proximity in about 30 min after injection.
