The present study was conducted to examine the nutritional requirements and growth of Mekong giant catfish (Pangasianodon gigas). The aspects studied were dietary protein, dietary requirement essential amino acids; methionine rates on growth performance and economic returns in productions of the species. The experiment was conducted at Kalasin Inland Fisheries Station, Thailand.
