Core tip: In the 48th week of 2025, the head price of Vietnam's basa fish ponds has seen a decline. The price for fish weighing 800–1300 grams in Tây Ninh province has dropped to 29,500–30,000 Vietnamese dong per kilogram, while larger sizes (over 1300 grams) remain at 30,500–31,000 Vietnamese dong per kilogram. Industry insiders point out that after the earlier period of sustained high prices, the breeding pace has slowed down due to climate influences and the purchasing pace has stabilized, leading to a technical correction in the market, but overall supply remains relatively tight.
