With the outbreak on global ecological and economic crisis, a mitigating technology in post-harvest Tilapia aquaculture was developed. This project (PartII) is focused on product standardization and verification analysis to answer the world’s food security/global sustainability problems. This innovative technology helped address the in-breeding concerns on Tilapia production, as well as the problems brought by climate change to aquaculture fishes. The developed product has undergone standardization procedures using single group experimental design. Analysis of Variance (ANOVA) was used in determining significant differences among treatment means. Verification analysis such as organoleptic testing, nutritional assessment and physico-chemical analysis were conducted to evaluate the product. Its nutrition profile was proven beneficial for health- conscious individuals bearing a good source of protein, trans fat, vitamin C and iron, with liked very much in all its attributes. The microbio-chemical analysis resulted on Level 1 satisfactory aerobic plate and Staphylococcus aureus counts, with marginal E.coli count while the iodine in salt content was moderate. Treatment 3 emerged as the best standardized production method accepted by the sensory panel, and was found shelf-stable for seven months. The technology has transformed the less marketable Tilapia into a profitable business venture while helping marginalized aquafarmers resolve problems on fishery losses in the Philippines.

The Philippine fisheries consists of the marine fishing, inland fishing and aquaculture sub-sectors. Aquaculture is the culture or farming of marine brackish water and freshwater species like the milkfish, tilapia, oysters, and seaweeds. Tilapia farming is rapidly obtaining global recognition today not just in the tropics like the Philippines but even in temperate and sub-tropical areas too. It is expected to contribute significantly in the food basket of the world’s growing population in the coming years. It is suitable for farming because it is relatively easy to breed and inexpensive to grow. Records reveal that the fisheries provide direct income and livelihood to more than a million fisherfolk and fishfarmers and indirectly to millions of other people (Bene,et.al. FAO 2007). With a contribution of about 5 % to the country’s gross domestic product, fish and other fishery products provides the supply of animal protein in the diet of an estimated 90 million population. However, with the global issue on climate change has markedly increased the average temperature of the earth’s surface. Such kind of phenomenon has brought about extreme catastrophic events like prolonged droughts (El Ninos) or stronger typhoons in the country. According to Guerrero (www.agribusinessweek.com) in the El Nino episode of 1997 to 1998, “the lack of rainfall caused heavy losses on our fisheries, particularly brackishwater ponds.” He added “about 20.6 % or utmost 41,000 hectares of brackishwater fishponds was adversely affected with losses of 10 percent to 80 percent of the cultured stocks valued at P 4 billion.” Reports revealed that the stocks were lost due to drying out of ponds, poor water quality, stunted growth (undersized and become less marketable) and mortalities. In the Bicol Region, the province of Sorsogon has been adopting an integrated farming system among the local fish farmers. It is noted that the said area is one of the highly risked areas...
