An expert from Kalasin University warns that the invasive tilapia (ปลาหมอคางดำ) has been in the Lam Pao reservoir for over a year and may spread into tributaries and the Chi-Phong basin as wind shifts in October and flood waters rise. Thai commentary estimates 2,500 million baht in damage to aquaculture, but the figure is not yet backed by published research. For Isan fish farmers and anyone buying fish from the Lam Pao area, this means watching for the yellowish-colored fish, avoiding releasing or moving live fish, and checking supply from affected waters.
