Nghe An farmers earn good profits from raising black apple snails in tarpaulin-lined ponds.
A farmer in Nghe An has turned a difficult-to-cultivate area into ponds for raising black apple snails using duckweed, earning hundreds of millions of dong each year.
The model of raising black apple snails in tarpaulin-lined ponds is a potential direction, especially in areas with poor soil, lack of irrigation water or difficult traditional agricultural cultivation. If invested in the right techniques and linked to sustainable consumption, this model will not only bring high income to farmers but also contribute to the development of ecological, circular and sustainable agriculture.
*)Outstanding advantages of the model:
- Effective control of farming environment:
Pond lining helps farmers easily control water quality, minimizing leakage and pollution from soil or external water sources. This is especially important for sensitive species like black apple snails. - Be proactive in disease prevention:
Raising snails in tarpaulin-lined ponds limits pathogens from the natural environment, makes it easy to clean the pond bottom, and helps reduce the rate of disease in snails. - Space saving, suitable for difficult to cultivate land:
The model is very suitable in places with sandy, acidic soil, or unfavorable soil for cultivation - taking advantage of abandoned areas, creating sustainable livelihoods. - Food sources are readily available and low cost:
Duckweed, water hyacinth, and discarded vegetables are natural, cheap, and easy-to-find food sources that are both cost-effective and environmentally friendly. This is the key factor that helps the model achieve high economic efficiency.
