紫菜深水翻台式养殖试验研究

Experimental Study on Deep-water Rollover Type Cultivation of Porphyra yezoensis

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7500 kg/hm^2,而传统养殖方式紫菜平均产量为5550 kg/hm^2;翻台式养殖方式投入35250元/hm^2,而传统养殖方式投入47250元/hm^2,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。

The experiment of Porphyra yezoensis cultivation was carried out in this paper,the growth and cultivation cost,differences between deep-water rollover type cultivation and traditional cultivation were compared,the test showed that the average yield,investment of rollover type cultivation per hectare were 7500 kg,35250 yuan,but the average yield,investment of traditional cultivation per hectare were 5550 kg,47250 yuan.The investment of aquaculture facilities in deep-water 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 deep-water 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.
