The closed recirculating system consisted of a fish tank of 1m3 in water volume, foam-separation and nitrification units, pH and temperature controlling units, and a circulation pump. A key feature of this system is the foam-separation unit, which is equipped with and air inhalation-type aerator that vigorously injects numerous fine bubbles into the rearing water. Fish were fed commercial pellet diet for 90 days. The survival rate of fish was 93.5%, and the gross weight of fish increased from 28.4kg to 50.0kg during the experiment in the closed recirculating system without the effluent. In the flow-through system, the survival rate was 98%, and the weight increased from 33.8kg to 64.1kg. Based on these recults, intensive aquaculture can be achieved with the closed recirculating system.}, pages = {818--825}, title = {泡沫分離・硝化システムによるヒラメの閉鎖循環式高密度飼育}, volume = {65}, year = {1999}, yomi = {マルヤマ, トシロウ and スズキ, ヨシヒロ and サトウ, ダイスケ and カンダ, タケシ and ミチシタ, タモツ and マルヤマ, トシロウ and サトウ, ダイスケ and カンダ, タケシ and ミチシタ, タモツ} }
