UPLB Develops Technology to Save 'Ayungin' from Extinction

Article excerpt

Researchers at the University of the Philippines at Los Baños (UPLB) have developed a surefire method to prevent the extinction of “ayungin,” a tasty fish indigenous to Laguna de Bay.The method calls for induced spawning of “ayungin,” scientifically known as Leiopotherapon plumbeus, outside of 949 sq. km. (94,900 hectares) lake, which has now overflowed, its waters inundating a number of Laguna towns and cities in Metro Manila.Laguna de Bay is also home to hundreds of fish pens and scores of urban poor communities.Under the process developed by scientists of the Limnological Research Station (UPLB-Limno) in Mayondon, Los Baños, chemical hormones are used to induce the spawning of “ayungin.”Dr. Pablo L. Ocampo, UPLB-Limno manager, said the technology may also be used not only to save the declining population of “ayungin” but also to protect and disseminate the population of certain fish species. …
