Operation plan: Back to the black tiger shrimp Culture models to revitalise its farming in the Philippines
Dr Leobert D de la Pena shared information on hatchery operations. Only disease-free post larvae tested at all three stages (PL5, PL10 and PL15) are stocked into ponds.

uring the 11th Philippines Shrimp Congress in 2017, Southeast Asia Fisheries Development Centre Aquaculture Department (SEAFDEC/AQD) Chief Dan Baliao introduced the “Oplan Balik Sugpo” program, a joint effort with the Bureau of Fisheries and Aquatic Resources (BFAR) to bring back Penaeus monodon farming. Similar to other countries in Southeast Asia, white spot syndrome virus (WSSV) decimated its farming in 1997. Production hovered at around 40,000 tonnes for several years (Mamauag et al., 2021) and led to the introduction of Penaeus vannamei farming in 2007. Industry estimated only 5,000 tonnes were produced in 2020, in contrast with 55,000 tonnes of vannamei shrimp (Hipon, 2021). Despite this much larger production of the vannamei shrimp, in Japan, the Philippines is still identified with the monodon shrimp.
Dr Roger Edward P Mamauag described the success to date in grow-out using lowwater exchange.

The aim of this program is to develop eco-friendly culture models, with enhanced biosecurity and proactive disease monitoring at hatcheries to encourage farmers to venture again into monodon shrimp farming. At the virtual 13th Philippines Shrimp Congress held from November 9-12, Dr Leobert D de la Pena, Head, Research Division, AQD, described the hatchery operations at the monodon shrimp spawner/broodstock facility in Iloilo. “In disease monitoring of broodstock, WSSV was prevalent in wild broodstock at almost 60% in 2020. Hatcheries then screen post larvae at PL5, PL10 and PL15 stages and only disease-free post larvae tested at all three stages are stocked into ponds. PL18-20 are transported for growout at the Dumangas Brackishwater Station in Iloilo.”
