The cultivation of Dam Xanh fish (Bangana lemassoni), a unique fish species, has seen remarkable growth in Mai Chau district, thanks to its high economic value and effectiveness. Initially concentrated in Van Mai commune, farming has now extended to four other communes, namely Mai Hich, Mai Ha, Chieng Chau, and Son Thuy. These areas benefit from pristine underground water flowing from mountain crevices, providing ideal conditions for raising this specialty fish.

Staff of the
Centre for Application and Scientific Information under the provincial Department
of Science and Technology guide people on how to introduce and trace the origin
of Mai Chau district's Bangana lemassoni fish products.
Despite its reputation as a sought-after delicacy, annual
production primarily serves a limited market of local visitors and tourists in
Mai Chau.
According to Kha Van Sanh, Chairman of the Van Mai communal
People's Committee, ca dam xanh, also known as Bong fish, is a signature
specialty of Mai Chau. The fish thrives only in clean water environments,
making it unsuitable for cultivation in typical ponds, lakes, or rivers.
Although slow to mature, its meat is prized for its exceptional sweetness and
flavour, offering significant economic potential. In recent years, local
authorities have promoted commercial farming, helping residents gradually
improve their incomes.
To bring this unique fish to a broader market, the Mai Chau
district People's Committee has partnered with the Centre for Application and
Scientific Information under the provincial Department of Science and
Technology. This collaboration successfully established the trademark "Mai
Chau district’s Bangana lemassoni fish", enhancing its market presence.
Ha Trung Thao, Vice Chairman of the Mai Chau district
People's Committee, emphasised the importance of protecting and promoting
products with distinctive regional characteristics. By supporting farmers in
building certified trademarks, local authorities have expanded the reach of ca
dam xanh, boosting its value and contributing to the district's socio-economic
and tourism development.
Before the trademark's establishment, farmers faced numerous
challenges, including low competitiveness and market instability, noted Tran
Dinh Thang, Deputy Director of the Centre for Application and Scientific
Information. Despite the fish’s high quality, the lack of branding and
organised distribution limited growth. Now, with certification and a clear
brand identity, dam xanh fish benefits from improved marketing, traceable
origins, and expanded distribution networks.
Kha Van Tu, Chairman of the Van Mai Commune Farmers'
Association, shared that since receiving the collective trademark
certification, demand for the fish has surged. Although priced between 200,000
and 300,000 VND (7.8–11.8 USD) per kilogram, sales volumes have increased
three- to fourfold for households in the commune. Moreover, the customer base
has expanded from local residents and restaurants to buyers from other areas,
highlighting the growing appeal of this specialty.
Dao Village’s honey – a product certified with a 3-star OCOP (One Commune One Product) rating by Thong Nhat Agricultural Cooperative in Dao Village (Hoa Binh City) – is highly regarded by consumers for its quality, richness, and variety in packaging. The distinctively sweet taste of Dao Village’s honey leaves a lasting impression on anyone who has tried it.
In alignment with Project No. 07-DA/TU, issued by the Hoa Binh provincial Party Committee on November 1, 2021, Lac Thuy district has actively promoted investment and supported the sustainable development of its industrial and handicraft sectors during the 2021–2025 period. Alongside this, the district has remained committed to preserving and revitalising traditional craft villages.
Located in the northern part of Lac Thuy district, with a temperate climate and fertile soil, Phu Thanh commune has great potential and advantages in growing tea. The long-standing experience, combined with strict adherence to organic farming practices in the tea gardens, ensures that the dried tea products from Phu Thanh and Lac Thuy as a whole are sold out immediately upon production, providing a stable and prosperous life for the local people.
Amid efforts to streamline the administrative apparatus, Hoa Binh province has intensified measures to address challenges in land clearance, resettlement support, and infrastructure investment, aiming to speed up the progress of key projects.
Hoa Binh province has posted an unprecedented economic growth rate of 12.76% in the first quarter of 2025, marking its highest quarterly performance to date and positioning it as the second fastest-growing locality in the country, trailing only Bac Giang province.
Under current regulations, products in the One Commune – One Product (OCOP) programme that are rated three stars or higher must undergo re-evaluation every three months. However, in reality, some of these products fail to consistently meet the required standards, raising concerns about the sustainability of their OCOP certification. This underscores the urgent need for producers to enhance product quality and gradually develop their OCOP products into strong, marketable brands.
