LAMPIRONG, also known as the Capiz oyster can be found in abundance around the seafood capital of the Philippines (Capiz, Roxas). It is known to be the only transparent mullosk. Capiz shells were once a thriving precursor of glass, used to make sliding windows during the Spanish occupation in the 19th century. More recently the shells, are used in the manufacture of decorative items. The unique Capiz shells are found in brackish waters. As filter feeders they can clean up to 40 litres/ hour, eating plankton and organic waste from rivers upstream. Making it an important presence in this vital ecosystem. Unfortunate the shells live in turbulent times. Bottom trawling, dynamite fishing, warming waters and stronger currents are declining populations. Communities depend on it for livelihoods and a clean environment.
