As the attention to the sea cucumber farming is increased, seed production and farming technologies are established through many researches. However, domestic researches on development of formulated feeds, which occupy more than 50% of the farming production cost, are few, and seaweed powder and artificial formulated feeds as feed for raising sea cucumber completely rely on import. As the needs for development of economic formulated feeds suitable for young sea cucumber, which is fed with formulated feeds for the first time, are issued according to the analysis of supply problems and economic feasibility of imported feeds, a formulated feed composition for young sea cucumber consisting of protein, carbohydrate, a ferment and a chewing substrate is designed by reviewing the balance of essential nutrients of existing fish and shellfish raising life and formulated feeds for sea cucumber. The growth effect of young sea cucumber and the applicability to the field of the developed formulated feeds are confirmed by conducting comparison breeding experimental on a growth effect of the formulated feeds for raising young sea cucumber seedlings according to the present invention and imported feeds for sea cucumber by comparing growth rates in an experimental tub. The present invention has an effect of sufficiently replacing the imported feeds, which sea cucumber seedling production companies completely rely on, by providing domestic economic formulated feeds compared to expensive imported materials.해삼 양식에 대한 관심이 증가하면서 종묘생산 및 양식기술에 대해서 많은 연구를 통해 확립되어 왔으나, 양식생산 비용의 50% 이상을 차지하는 배합사료 개발에 관한 국내 연구는 거의 없으며, 해삼 양성용 먹이로 해조류 분말이나 인공배합사료를 전적으로 수입에 의존하고 있는 실정이다. 수입사료의 수급 문제점 및 경제성이 분석되면서 배합사료를 처음으로 공급하는 어린 해삼에 적합한 경제성 있는 배합사료의 개발의 필요성이 제기됨에 따라 기존의 어패류 양식생물 및 해삼 배합사료의 필수 영양소 균형을 검토함으로써, 단백질, 탄수화물, 발효원 및 씹는 기질로 이루어진 어린해삼 배합사료 조성물을 설계하였다. 본 발명에 따른 어린해삼 종묘육성용 배합사료와 수입산 해삼사료의 성장효과에 관하여 실험수조에서 성장률 측정 비교 사육실험을 수행함으로서, 개발된 배합사료의 어린해삼의 성장 효과와 현장 적용 가능성을 확인하였고, 값비싼 수입원료에 비해 국내의 경제성 있는 배합사료를 제공함으로
