The project, "Long term evaluation of dehulled soybean meal (DHSBM) as fish meal (FM) replacement for flounder (from growing size to commercial size) at the practical fish farm", is the cooperative research between the United Soybean Board/American Soybean Association/Korea (Say Young Jo, Country Director) and Feeds & Foods Nutrition Research Center (Sungchul C. Bai, Director) attached to the Pukyong National University. The goal of this project was to evaluate the possibility of utilizing of Dehulled Soybean Meal (DHSBM) as a fish meal replacement in flounder reared at the practical fish farm for a whole production period.

The research lasted for about 12 months in Pohang, Korea. Four experiments were : (1) Evaluation of the effect of dehulled soybean meal as fish meal replacement on growth of flounder from grower to market size at the commercial fish farm; (2) Evaluation of water pollution parameters; (3) Economical evaluation; (4) Investigation of the palatability of flesh. The results indicated that dehulled soybean meal could replace up to 30% of fish meal from the growing size to commercial size of flounder with the supplementation of attractant. When considering the pollution degree and economic effect, the formulated feeds based on further researches on the proper replacement levels of dehulled soybean meal in different fish species should be developed in the future.
