Tridacna squamosa, otherwise known as Giant Clams, have been feeding islanders for thousands of years, however, out of control harvesting has led to extinction in many regions, especially the islands of Singapore.
Mariculture with regards to Giant Clams can produce juveniles in large enough numbers to restock wild populations.
The 60 small islands surrounding Singapore have coastal development which has heavily damaged the corals reefs, damaging clam populations as well. However careful resettlement programs can be very successful.
Despite high levels of sedimentation and turbidity on Singapore's reefs, giant clams can survive and grow well. Restocking efforts using maricultured clams may be effective in enhancing the dwindling local populations. It is not clear, however, whether a self-sustaining community can be established as high sedimentation may hinder larval settlement and survival.
Giant clams (Tridacnidae) are a family of bivalve molluscs that live in tropical waters on coral reefs. They are unique due to their large size and very specialized feeding mechanism. The largest giant clam species, Tridacna gigas, is the largest two-shelled (bivalve) animal that has ever existed. There is nothing in the fossil record that can match it. This clam may be up to 1.3 m long and weigh up to 500 kg. While not all 11 species of giant clam are this size — they range from 15 cm to 1.3 m shell length, with the majority in the 40–50 cm range — they are all large compared to typical bivalves, such as oysters, mussels and scallops.
