Combined effects of population growth, people's increased income, and fierce competition with increased demand in biofuel have seriously affected food production, as well as people's livelihood in the Asian and Pacific region. On-going g lobal warming and economic depression are expected to further deteriorate food production, thus resulting in steep increases in food p rices .
In view of the aforementioned situation, the fishery sector has to take the most effective ways to improve various key technologies because both aquaculture and fisheries are generally considered to be inefficient, energy-consuming , and an industry that is not environmentally- friendly. There is an urgent need for the fishery sector, therefore, to develop various innovative technologies toward much greener, environmentally safer and more competitive compared to other major sectors in the seafood industry.
To cope with the growing concerns over the said technology innovation, in practical terms, there are two effective approaches: 1) Processing fisherywaste into value-added products, 2) Introduction and/or integration of promising practical technologies into fish farming and fish catching for reduc ed production cost and seafood safety.
Waste problems in the fishery sector become serious every year. A large amount of underutilized biomass has to be treated as waste even if Good Aquaculture Practices (GAPs) and GMP in seafood processing are applied. In the industrial processing of tilapia fillets for example, the yield is only about 33%-36%, at most while the remaining 64-67% are generally dried to make fish meal; the breakdown of the remaining portions are as follows: 4%, scale 3%, fish head 22%; bone 9%, trim meat 8.5%; belly 5.5%; viscera 10.5%; and blood 1.5%
If the aforementioned portions can be processed into value-added products, we will be able to kill two birds with one stone; that is, a drastic decrease in fishery wastes and production of new high value fishery products and development of the associated new innovative technology. One of the promising targeted areas is the conversion of fish skin and scales into fish collagen peptide which can replace the porcine counterparts. The latter may possess a potential risk of foot-and-mouth disease. Recently the fish collagen is growing in popularity as raw materials of nutraceuticals, cosmetic and health care products. Promotion of recycling and reduction of fishery wastes should therefore be a primary concern of the fishery industry.
The recent price-hike and increased consumption of energy are to make the fishery sector more vulnerable to competition with other dominant sectors, so that there is an urgent need for less costly, more efficient and sustainable energy sources. Including reusable ones, applications of LED light and solar panel are alternative replacements to incandescent lamp and heavy oil-based fuel which are widely used in the fishery industry.
This international seminar seeks to gather experts from various fields related to the fishery sector, food and environmental safety, energy-saving technology, green technology, recycling of fishery wastes for innovative value-added products, nutraceuticals, cosmetics and health care.
