Kalasin provincial fisheries officials say suspected black chin tilapia (ปลาหมอคางดำ) have appeared in Lam Pao Dam, a large reservoir used by people for fishing and for cage-raising Nile tilapia and giant freshwater prawns. Preliminary lab results from the Department of Fisheries point to the species; official written confirmation is expected within the week. A deeper field inspection with provincial officials is planned for 12 September, and the Director of the Freshwater Fisheries Research and Development Division will attend in person. If you raise fish or prawns in cages or sell catch from Lam Pao, expect inspections and possible restrictions, and watch for the official confirmation before moving stock.
