Tridge summary

Since 2018, Quang Binh Province in Vietnam has been experimenting with a shrimp farming model on inefficient rice land, with initial successes raising crayfish and later introducing all-male giant freshwater prawns. This model, which involves converting rice farms into ponds for shrimp culture, has demonstrated high economic potential, despite challenges like the Covid-19 impact on selling prices. The project has seen significant survival rates and reasonable yields, with each household earning an average profit of 120 million VND after expenses. The practice has received positive feedback and is being adopted by other areas, with the province providing support and guidance. The success of this initiative is seen as a step forward in applying scientific advancements in aquaculture and encouraging farmers to adopt sustainable, profitable farming practices.

In order to exploit the potentials and advantages of saline and inefficient rice land , since 2018, Quang Binh Provincial Center for Agriculture and Fisheries Extension (KN - KN) has piloted a shrimp farming model. more green on this land in some localities in Le Thuy, Quang Ninh and Bo Trach districts. The results from these experimental farming models show that the "crayfish" is well adapted to the climatic and soil conditions of Quang Binh province, bringing economic benefits to the farmers. From the achieved results, at the beginning of March 2021, Quang Binh Agriculture and Science Center continued to replicate the model of all-male giant freshwater prawn farming on converted rice land associated with product consumption in 8 farming households in communes. Hong Thuy (Le Thuy district), Gia Ninh, Ham Ninh, Vinh Ninh (Quang Ninh district) and Duc Ninh (Dong Hoi city) with an area of 4.7ha. Farming sites are areas where rice was previously grown but inefficiently converted to ...
