Raising frogs in a closed-loop system.
The frog farming area of Mr. Phan Van Man Anh, residing in Tan An hamlet, attracts many neighboring farmers who come to visit and learn from his experience. Starting with just a few initial breeding pens, he has now expanded his model to an area of approximately 1,300 square meters around his house and along the riverbank. In early 2023, he joined a frog farming professional group established by the Farmers' Association of Tan Hiep B commune (now Tan Hiep commune). Initially, the group had only 6 members, mainly engaged in small-scale farming. After a period of successful operation, the number of members increased to over 20, working together in production and providing each other with technical support.

What sets Mr. Man Anh's model apart is raising frogs in combination with tilapia or catfish in the same net enclosure. According to him, this method helps utilize excess food and reduce water pollution. "Each enclosure, about 32 square meters , holds approximately 6,000 frogs, with tilapia or catfish underneath. The fish eat the leftover food, and the frog droppings and skin shed make the water cleaner, resulting in fewer frog diseases," Mr. Man Anh shared.
Thanks to proactive management of the breeding environment, the frog population developed steadily, significantly reducing losses. After many successful breeding seasons, he continued to research frog breeding models to become self-sufficient in breeding stock. Initially, forcing frogs to breed proved difficult due to low hatching rates and high mortality rates of the offspring. Undeterred, he learned more about breeding techniques through documents, gained experience from seasoned breeders, and gradually adjusted his care process.
According to Mr. Man Anh, to have healthy breeding stock, it is necessary to carefully select the parent frogs. Female frogs should be long-bodied and strong; male frogs should be agile and uniformly developed. The parent frogs are raised separately for about 8 months before breeding. Their diet includes digestive enzymes, vitamins, and aquatic products to boost immunity, stimulate egg production, and increase hatching rates.
Currently, in addition to raising frogs for meat, he also supplies froglets and frog eggs to members of the professional group and local people. Each breeding cycle lasts about 3 months. After deducting expenses, the profit reaches about 70-80 million VND per cycle, with a total annual income of about 200 million VND.

Mr. Le Ngoc Hai Phong, from Dong Loc hamlet, chose a farming approach that suits his circumstances, allowing him to both pursue his professional work and develop his family's economy . As a master's degree holder in aquaculture, he utilizes his specialized knowledge to implement a model of raising pheasants for eggs combined with raising black snails. For him, this model doesn't require much land but still provides a stable income if properly cared for.
In mid-2025, he started raising about 30 breeding pheasants. To date, the flock has grown to 56 birds, currently in the breeding stage. The birds are raised at a ratio of 1 male to 3 females. Their feed mainly consists of commercial feed supplemented with minerals and vitamins to increase egg production. Currently, the flock produces about 40 eggs per day. With a selling price of around 8,000 VND per egg, after deducting expenses, he earns a profit of about 8 million VND per month. In addition to selling commercial eggs, he has also invested in an electric incubator to produce his own chicks for restocking and to sell to other farmers in the area.
Besides raising pheasants, Mr. Phong utilizes his approximately 600m² pond to raise black snails. "The advantage of this model is the low cost because the main food source is green vegetables, duckweed, water hyacinth, and readily available agricultural by-products," Mr. Phong explained. To ensure a steady supply of snails, he collects the eggs, places them on trays in styrofoam containers lined with damp cloth, and allows them to hatch naturally. Although commercially sold snails currently fetch prices ranging from 60,000 to 80,000 VND per kilogram, he hasn't sold them yet, focusing instead on producing snail hatchlings to expand his stock and supply local residents.
Ms. Pham Thi Thu Trang, Chairwoman of the Tan Hiep Commune Farmers' Association, stated that the frog farming, pheasant breeding, and seed production models implemented by association members demonstrate the dynamism and initiative of farmers. Using their existing pond and garden areas, many households have boldly applied advanced techniques to livestock farming, securing their own breeding stock and generating stable income for their families. This development direction is well-suited to local conditions, contributing to expanding livelihoods and improving the economic efficiency of rural areas.
