Khe Tien village in Quang Ninh province has become the first in the region to implement a cold-water fish farming model, specifically for Siberian sturgeon. The model was first introduced in 2015 and has since seen high-quality post-harvest fish due to the sturgeon's successful adaptation to the water flow. The village has made several infrastructural adjustments to promote the sturgeon's development and now follows the VietGAP standard process for farming. Khe Tien is also emerging as a tourist hotspot, attracting visitors with its natural beauty and traditional indigenous culture.
