Agriculture Business Week

August 14, 2008 was just another ordinary day for the rest of the townsfolk in Magallanes, Agusan del Norte. But in the three-hectare pond of Mr. Jimmy Viray in Barangay Caloc-an of this town, it was a red letter day brimming with excitement, teeming with hope. It was another harvest time but what made it extraordinary and significant was that for the first time in six years, Mr. Viray and his men were going to harvest prawns that have completed one full cropping period. Their prawns lasted 120 days. While the other ponds were forced to harvest at 60 days due to early signs of inevitable high mortality, theirs had remained intact and had miraculously overcome the 60-day syndrome.

Mr. Viray’s pond is the first Demo Pond of Aqua Plus in the area and the first to use it. Aqua Plus, a liquid concentrate of live beneficial microorganisms and one of the brands of Bio Organic Plus Philippines, Inc., producer of probiotic products. The venture was financed by the BCB-MPC (Baug CARP Beneficiaries-Multipurpose Cooperative) of which Mr. Viray is a member. Together with technician Mr. Manulito V. Porio and caretaker Mr. Elgenio Pilo, they raised their hopes for a better produce using Aqua Plus Brand for the entire period.

Prawn industry in Magallanes and nearby towns used to be very lucrative and enriching venture. Until 2002, a plague called white spot virus invaded and contaminated all the ponds and for those which persisted, emergency harvest at 60 dayS became a byword, for if not done, the virus would give them 100 percent mortality and zero income. For a three-hectare pond with 150,000 stockings, it used to give them 2.5-3 tons (2,500 – 3,000 kilograms) of prawns but with the onset of the virus, they had to be contented with 100-300 kgs. per harvest. Most of them wondered how they could ever get out of the plague.

A biology professor from the Mariano Marcos State University (MMSU) in Batac, Ilocos Norte, has found the basic knowledge that could help control vibriosis, the disease that has inflicted much damage to the multibillion dollar tiger prawn industry in the Philippines.

Vibriosis has caused the downfall of the shrimp industry in the Philippines as well as in other Asian countries. The bacterium Vibrio harveyi has been implicated as the cause of vibriosis.

With the collaboration of Dr. Cynthia T. Hedreyda of the UP National Institute of Molecular Biology and Biotechnology in Diliman, Quezon City, Dr. Prima Fe T. Franco found that in order to gain insights on the disease causing mechanisms of Vibrio harveyi, she had to study the genes and protein implicated in pathogenecity, one of which is toxR.
