In recent years, the model of combining fish farming in rice paddies and vegetable cultivation on dikes has gradually proven to be highly effective economically, benefiting both agricultural production and the environment in Long My town, Hau Giang province.
The model of raising fish in rice paddies and growing vegetables on the banks takes advantage of the benefits of combining fish farming and crop cultivation, allowing farmers to increase their income from multiple sources.
Specifically, during the rice growing season, the rice fields are used for fish farming, while the embankments are utilized to grow crops such as beans, green vegetables, or other flowers.
This not only enhances biodiversity and optimizes land use, but also increases income by 20-30% compared to growing rice or raising fish separately.
Fish raised in rice paddies can reach optimal weight when the rice harvest is complete, while vegetables grown on the embankments also provide a stable income.
Utilizing water and food from rice paddies to raise freshwater fish helps reduce fish feed costs. Additionally, fish waste can be used as organic fertilizer for the fields, further reducing input costs.
This model creates numerous job opportunities for local workers, ranging from caring for and harvesting freshwater fish and crops to jobs related to processing and selling the products.
This is a fish farming model, featuring freshwater fish in rice paddies and vegetable cultivation on the dike banks, implemented by Mr. Ho Ngoc Binh in Hamlet 7, Long Tri A Commune, Long My Town, Hau Giang Province.
Planting crops along the embankments helps prevent erosion and protect the soil, while also improving soil quality. This model also helps maintain and improve the field ecosystem, protect water resources, and enhance biodiversity.
Currently, many localities in the Southwestern region of Vietnam, such as Dong Thap, Can Tho, An Giang , and Hau Giang provinces, have successfully implemented the model of raising fish in rice paddies and growing crops on embankments.
Specifically, in Long My town, Hau Giang province, as of early August 2024, according to the economic department's report, the total area for rice paddy fish farming was 607.85/1,045 hectares of aquaculture area, accounting for 58.17% of the total area.
Mr. Ho Ngoc Binh, a farmer in Hamlet 7, Long Tri A Commune, Long My Town (Hau Giang Province), who is applying the integrated model, said: “I am very satisfied with this model because it only costs money for nets, fish fry, ducklings, and seeds. There are no costs for fish feed, only a little feed for the ducks and little fertilizer for the plants grown on the dike (bitter gourd), and it requires very little labor for care...”.
According to Mr. Binh, the harvest after 3 months includes farmed fish, wild fish, snails, crabs, ducks, and bitter melon. This model brings in a relatively high income during the flood season.
"The estimated total cost is around 20-30 million VND/ha, with a total revenue of 80-90 million VND/ha. Therefore, I earn a profit of about 60 million VND/ha/crop during the flood season. If I grow a third rice crop, the profit is only 30-40 million VND/ha. In addition, the fish waste increases soil fertility, saving money on fertilizer. I believe this is a sustainable solution for agriculture.”
To optimize the effectiveness of the rice-fish farming and crop cultivation model, experts recommend continued research and improvement of fish farming and crop cultivation techniques. Simultaneously, training and supporting farmers in applying the model also plays a crucial role in expanding it to other areas.
The model of raising fish in rice paddies combined with growing crops on the dikes not only helps increase income for farmers in Long My town (Hau Giang province).
This integrated fish farming and crop cultivation model also contributes to environmental protection, creates a sustainable agricultural ecosystem, protects native aquatic resources, and promotes sustainable agricultural development. It is a prime example of combining traditional and modern agricultural production methods to achieve high economic efficiency and protect the environment.
