Fish cage culture catches on in Nepal

19.04.2010
For most of the 2,000 people who had to abandon their homes, fish farming turned misfortune into opportunity.

More than 20 years after the introduction of aquaculture, fish farmers are thriving in Kulekhani, Nepal. Researchers supported by the International Development Research Centre guided the first families into this new venture when the construction of a hydro dam flooded the area in 1982.

For most of the 2,000 people who had to abandon their homes, fish farming turned misfortune into opportunity.

Researchers at the Nepal Agricultural Research Council found that the water was ideal for raising fish — mostly carp species — in large floating cages. The fish thrive on plankton readily available in the water.

The majority of the displaced families soon adopted fish farming as their new livelihood and prospered on the shores of the reservoir. There is also a smaller but equally successful catch fishery, boosted in part by “escapees” from the fish cages.

With new-found financial security, more families are able to provide education for their children, unlike many rural communities in Nepal. And the role of women in decision-making has been strengthened. Women take part alongside the men in all activities, from cleaning and repairing the fish cages to participating in meetings of farmers’' associations, attending workshops, and marketing the catch.

“There are some 1,100 to 1,200 fish cages and average production is estimated at 120 to 130 metric tonnes per year.”

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
