‘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: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
