摘要 通过进行条斑紫菜养殖试验，比较了深水翻台式养殖与传统养殖模式下条斑紫菜的生长情况及养殖成本，试验表明深水翻台式养殖方式紫菜平均产量为7 500 kg/hm2，而传统养殖方式紫菜平均产量为5 550 kg/hm2;翻台式养殖方式投入35 250元/hm2，而传统养殖方式投入47 250元/hm2，养殖设施资金投入深水翻台式养殖明显低于传统养殖;同时，养殖区由浅海向深海延伸，也极大地拓展了养殖海域，提高了海区利用率。由此可见，深水翻台式养殖方式产量高，质量好，结构简单，组装方便，降低了成本的同时，提高了海区利用率，是提高紫菜养殖效益的一种有效养殖模式。

Abstract The experiment of Porphyra yezoensis cultivation was carried out in this paper，the growth and cultivation cost， differences between deepwater rollover type cultivation and traditional cultivation were compared，the test showed that the average yield，investment of rollover type cultivation per hectare were 7 500 kg，35 250 yuan，but the average yield，investment of traditional cultivation per hectare were 5 550 kg，47 250 yuan.The investment of aquaculture facilities in deepwater rollover type cultivation was obviously lower than that of traditional cultivation.At the same time，the breeding area extends from shallow sea to deep sea also greatly expanded  and increased the utilization rate of sea area.Thus it can be seen，with high yield，good quality，simple structure and convenient assembly，the deepwater rollover type cultivation method reduced the cost and improved the utilization rate of the sea area，which is an effective breeding mode to improve the efficiency of P.yezoensis cultivation.

紫菜是我國藻类养殖的第二大品种，创汇的主导品种之一，紫菜养殖在我国有着悠久的历史，是我国水产养殖业的代表之一，其规模在藻类养殖中仅次于海带。2016年我国紫菜产量约13.53万t[1]，产值超过100亿元，在我国海藻养殖业中占有重要地位。干紫菜中粗蛋白含量达30%～50%，富含膳食纤维、多种维生素及钙、钾、镁等微量元素，还含藻类特有的藻胆蛋白，具有很高的营养价值[2-3]，是一种不可多得的海洋食材，也是我国东南沿海农村经济的支柱产品。

然而，随着近海养殖规模化扩大，养殖筏架杂藻滋生，养殖海域面积逐渐饱和，养殖密度过大，加之近年来生态环境保护意识加强，养殖海岸线向外延伸，藻类近海养殖出现诸多问题。……
