Tobacco is not an only major ingredient in the manufacture of cigarettes, but also could be used for sustainable aquaculture that could increase farmers and fisherfolks income. NTA administration Edgardo D. Zaragoza led a "show and tell" activity at a demonstration farm in the municipality of Sto. Tomas, La Union, on how tobacco dust could address the degradation of fishponds due to the use of highly toxic chemicals. This has been proven in a series of studies conducted by the NTA in collaboration with Southeast Asian Fisheries Development Center, the Iloilo School of Fisheries in Iloilo, the DOST/Philippine Council for Aquaculture and Marine Resources Research and Development (PCAMRRD) and the BFAR, especially in Region III (Bulacan, Pampanga, Bataan) and Region I (Pangasinan and Ilocos Sur), he added.
