The first ever in-situ spawning of the Palawan native species of the biggest giant clam, Tridacna gigas, was commenced by Malampaya Foundation and partners to help increase its declining population at Western Philippines University Hatchery in Binduyan, Puerto Princesa City. University of the Philippines Marine Science Institute, forerunner of giant clam conservation in the Philippines, supervised the spawning activity where about 9.5-million eggs were fertilized from native giant clams located at Dos Palmas. According to Dr. Lota A. Creencia of WPU College of Fisheries and Aquatic Sciences, “Tridacna gigas is hard to propagate because the population is few. We need to really go to the brood stock [source] to collect eggs and sperms, compared to other species of clams which numbers can still afford to be brought into laboratories.”
