The all-time favorite in many Filipino grills, tuna belly and panga, come all the way from the Marshall Islands. Tuna traders import from Majuro and Vietnam (the major sources) as well as South Korea tuna scraps like belly, panga buntot and even bihod and shipped directly to Davao, General Santos or Manila. They are called "scraps" because tuna meat is the premium part but are actually value-added products.
