History

edit

Diadi was formerly a barangay of Bagabag named Picat. It was originally founded by the Spaniardsin the 18th century at the summit of Mount Namamparang, before being moved into the bottom of the same mountain. The settlement served as a garrison and rest stop along the mountain road between Isabela and Nueva Vizcaya, which was frequently plagued by pagan headhunters, and a resettlement site for christianized Ifugaos and Ilongots.[5]

House Bill No. 182, titled "An Act Creating the Municipal District of Diadi in the Province of Nueva Vizcaya," was introduced by Congressman Leonardo B. Perez on February 28, 1966. It was subsequently approved by the Committee on Provincial and Municipal Governments in Committee Report No. 54. Later, in May 1967, Senator John Osmeña issued Committee Report 1053 recommending passage of the Bill. On 17 June 1967, R.A. 4973 was approved by both chambers of Congress, thus creating the Municipality of Diadi.[6]

Tilapia industry

edit

On January 11, 2008, the Cagayan Bureau of Fisheries and Aquatic Resources (BFAR) stated that tilapia production grew and Cagayan Valley is now the Philippinestilapia capital. Production supply grew 37.25% since 2003, with 14,000 metric tons (MT) in 2007. The recent aquaculture congress found that the growth of tilapia production was due to government interventions: provision of fast-growing species, accreditation of private hatcheries to ensure supply of quality fingerlings, establishment of demonstration farms, providing free fingerlings to newly constructed fishponds, and the dissemination of tilapia to Nueva Vizcaya (in Diadi town). Former cycling champion Lupo Alava is a multi-awarded tilapia raiser in Bagabag, Nueva Vizcaya. Chairman Thompson Lantion of the Land Transportation Franchising and Regulatory Board, a retired two-star police general, has fishponds in La Torre, Bayombong, Nueva Vizcaya. Also, Nueva Vizcaya Gov. Luisa Lloren Cuaresma also entered into similar aquaculture endeavors in addition to tilapia production.[20]
