不同换水量、吸污后水中的溶解氧变化对工厂化养殖的成活率具有相当重要影 响．本文对牙鲆工厂化养殖进行现场跟踪监测,在养殖水体换水率5～6倍／d,吸污次 数在2次／d,养殖水体中溶解氧变化均在牙鲆生长正常范围内,其成活率高达80％ 以上,成功调控养殖水质,极大降低了工厂化养殖牙鲆的生产成本．
Different water changes, changes in dissolved oxygen in water after sewage absorption on the survival rate of factory farming has a considerable impact. In this paper, the Japanese flounder industrialized on-site monitoring tracking in the aquaculture water exchange rate of 5 to 6 times / d, the number of sewage in 2 times / d, aquaculture water dissolved oxygen in flounder growth within the normal range, the Survival rate of up to 80% or more, the successful regulation of aquaculture water quality, greatly reducing the cost of production of Japanese flounder farming.
