Home>Major Activities>Seminars and Workshops in 2010>Improved Utilization of Fishery By-products as Potential Nutraceuticals and Functional Foods

October 25-29, 2010
Bangkok, Thailand
Kasetsart University, Thailand
Background / Highlights of Activity

Harvesting of seafood is continuously rising due to its increasing consumption for its many proven health benefits. This in effect has led to the abundance of by-products, as can be seen from the frozen and canned seafood industry in the Asian region where tons of exoskeleton are discarded annually. Commercial processing of aquatic foods requires removal of bones, skin, head, and viscera (by-products), which account for approximately 60-70g/100g of the weight. Most by-products have traditionally been cheaply sold mainly for use in fishmeal production, hauled into the ocean, or dumped on land. Nowadays, however, the land filling practice is under strict environmental and regulatory scrutiny due to limited land and to increased environmental concerns such as groundwater contamination and stench problems. Compliance with environmental standards and a better understanding of the potential values of processing discards for a variety of applications have resulted in efforts to find uses for seafood wastes as value-added products. Currently, there has been a growing interest in natural ingredients which are readily available from seafood discards. However, the lack of adequate utilization technology to fully convert such wastes into value-added products must be seriously addressed. The importance of functional foods, nutraceuticals, and other natural health products has been well documented as contributing to health promotion, disease risk reduction, and reduction in health care costs. Processed seafood by-products are now considered as a good concentrated source of components with health beneficial effects. However, lack of proper knowledge on waste utilization technology pose negative effects on the bioactive components of functional foods and nutraceuticals products. Therefore, knowledge and availability of waste utilization technology leading to effective waste management is of vital importance particularly in increasing the quality of value-added products from seafood wastes.


  1. To share relevant information on potential fishery by-products resources for value-added products (nutraceuticals and functional foods);
  2. To promote and exchange waste utilization technology and information among countries in the Asian and Pacific region;
  3. To expand research collaboration on fishery-waste utilization technology to contribute significantly to the ability of countries in the region to increase by-products utilization; and
  4. To promote awareness on environment-friendly disposal of wastes by the seafood industry.
