(seafood.vasep.com.vn) Amid the increasingly evident impacts of drought and saltwater intrusion, the shrimp-rice production model in Ca Mau province continues to prove itself as a viable direction, contributing to higher farmer incomes, improved soil conditions and the promotion of ecological and sustainable agricultural development.

Formed over several decades, this model leverages seasonal salinity-freshwater cycle, cultivating rice cultivated during the rainy season and farming shrimp during the dry season. As climate change renders monoculture rice farming less effective, the shrimp-rice system is regarded as a flexible adaptation solution that delivers stable economic value. In Ca Mau, this model has been identified as one of the key production orientations under the agricultural sector restructuring strategy.
Local farmers across the province are currently in the peak harvest season for rice grown on shrimp-farming land, while simultaneously preparing for the first shrimp crop of early 2026. The shrimp-rice fields are bustling, as both crops have seen favorable yields and stable market prices. In Bien Bach and Vinh Loc communes, giant freshwater prawns are being purchased by traders at prices ranging from 70,000 to 120,000 VND/kg, boosting farmers' income by tens of millions of dong per hectare.
According to Ca Mau Department of Agriculture, the province currently has over 93,000 hectares under rice–shrimp production. Farming efficiency has continued to improve through the application of technical advancements and reduced use of chemicals, contributing to the protection of wetland ecosystems and enabling farmers to proactively adapt to weather-related risks, toward ecological, organic and sustainable agricultural production.
