'Awakening' the sandy region

QTO - Along with intensive, high-tech shrimp farming from many years ago, recently, many models of farming aquatic species such as abalone, kingfish, red-tailed catfish, etc., have brought high economic efficiency, transforming the white sand area of ​​Nam Cua Viet commune into a fairly vibrant production zone.

After many years living and working in the former Khanh Hoa province, in 2025, Mr. Truong Van Duc from Phu Hoi village, Nam Cua Viet commune, returned to his hometown and planned to establish a long-term business raising red-tailed catfish and crucian carp on an area of ​​more than 4,000 square meters of white sand.

According to Mr. Duc, he boldly chose red-tailed catfish and crucian carp to experiment with farming in the sandy area of ​​Nam Cua Viet commune. From around August 2025, he released 13,000 crucian carp and 7,000 red-tailed catfish fingerlings. Red-tailed catfish are easy to raise and have the highest economic value among catfish species on the market. Furthermore, red-tailed catfish can be raised in cages with other fish species such as crucian carp, common carp, and grass carp…

Mr. Duc selected and purchased the catfish fingerlings from a reputable source; the fish are healthy, uniform in size, and weigh an average of 10g each. It is expected that after 10 months of rearing, the catfish will reach a weight of over 1kg each. Furthermore, red-tailed catfish have high nutritional value, and their meat is softer and more flavorful when cooked, making them easier to sell and more expensive than other catfish varieties. Currently, the price of red-tailed catfish sold at the pond is around 100,000 VND/kg.

Crucian carp, in particular, is a hardy fish, easy to raise, requires low investment and little effort, and its meat is delicious and used as a medicinal remedy and to nourish the body. Crucian carp are omnivorous, so they can be fed rice bran, commercial pellet feed, or agricultural by-products.

After 4-5 months of rearing, the fish reach marketable size of 100-200g/fish, with the current selling price around 150,000 VND/kg. From the beginning of 2026 until now, Mr. Duc has started harvesting the crucian carp to sell to traders and has earned over 50 million VND. It is expected that the red-tailed catfish and crucian carp farming model will bring in an income of over 200 million VND/year.
