In 1992 the ABC environmental program “A Question of Survival” broadcast this story about giant clams and a joint Australian-Fijian project to breed these massive creatures in captivity.
Giant clams are an important food source in the South Pacific, but widespread poaching in the 70’s and 80’s had devestated the natural population. The research project found a method to breed baby clams and grow them in captivity until they were big enough and tough enough to survive and flourish on their own, and then re-locate them back to the ocean.
