History

Previously, Diadi was a barangay of Bagabag. On 28 February 1966, then Congressman Leonardo B. Perez filed House Bill No. 182 entitled “An Act Creating the Municipal District of Diadi in the Province of Nueva Vizcaya”. It was subsequently passed through Committee Report No.54 of the Committee on Provincial and Municipal Governments. Then, on May 1967, Senator John Osmeña, Jr. recommended the approval of the Bill through Committee Report 1053. On 17 June 1967, R.A. 4973 was approved by both chambers of the Congress, thus creating the Municipality of Diadi.[5]

Tilapia industry

On January 11, 2008, the Cagayan Bureau of Fisheries and Aquatic Resources (BFAR) stated that tilapia production grew and Cagayan Valley is now the Philippines’ tilapia 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.[9]
