‘Ayungin’ (Leiopotherapon plumbeus) target of conservation attempt by researchers

29.04.2009
A research project at the University of the Philippines Los Baños is underway to save from threat this freshwater fish. Dr. Pablo P. Ocampo of the UPLB Limnological Research Station has established a captive breeding program to save the 'ayungin' (Leiopotherapon plumbeus).

Ayungin (Leiopotherapon plumbeus), a freshwater fish species endemic in the Philippines, is thinning in population. It is a small silver-colored fish used to be plentiful in the country’s freshwater bodies such as Laguna de Bay. Its overfishing by local fishermen mainly for duck feeds and family consumption have now made it scarce.

Considered as the tastiest fish among all the edible native freshwater species in the Philippines, ayungin is now rarely sold in the market. When available, it costs as much as P500 per kilo.

A research project at the University of the Philippines Los Baños is underway to save from threat this freshwater fish. Dr. Pablo P. Ocampo of the UPLB Limnological Research Station has established a captive breeding program to save the ayungin.

Dr. Ocampo reported that ayungin collected by the project from Laguna de Bay has been successfully maintained in the station’s concrete tanks. The collected ayungin broodstock was found responding well to a specially formulated diet combination of commercial prawn feeds and Tubifex worms.

The project is now studying ways on how to induce the ayungin to naturally spawn in an artificial environment. While simulated rain, flowing water, vegetation, sand and soil have been incorporated into the artificial environment, the research station’s findings suggest that ayungin from the wild may find it to naturally reproduce in captivity.

Nonetheless, Dr. Ocampo reported that the rearing techniques used are being refined. Experiments are underway to determine whether live feeds may help the ayungin to breed inside the tanks.

Hopefully, the captive breeding techniques being researched on may come to fruition. With success, the project can provide more Filipinos the chance to taste and savor once again the traditional delectable dishes prepared from ayungin.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
