摘　　要：红毛菜是一种富含二十碳五烯酸(EPA)等脂肪酸的高值经济海藻,是福建省特有的养殖藻类。为进一步促进红毛菜养殖的发展,解决传统筏式养殖存在的杂质高和烂菜等产业问题,厦门大学与霞浦县水产技术推广站等单位联合利用海带育苗玻璃库房开展了红毛菜叶状体悬浮扩培的养殖试验。试验结果表明:以50 L薄膜袋气升式光生物反应器和1000 L白色塑料桶作为培养器具,红毛菜叶状体的日生长率最大分别可达到18.18%·d^(-1)和21.39%·d^(-1),远高于网帘的室内水泥池养殖和海区筏式养殖;灰分和粗脂肪含量对比传统海区筏式网帘养殖分别提高20.81%和25.00%,蛋白质含量降低了18.15%,同时不饱和脂肪酸含量等品质指标也优于后者;陆基养殖可避免海区养殖的杂质污染,对提升红毛菜加工效率与质量具有重要价值。本文首次报道了红毛菜叶状体的陆基养殖工作,将为大型海藻设施化养殖提供新的模式与技术。Bangia fuscopurpurea is a kind of high-value economic seaweed rich in EPA and other fatty acids and it is a unique cultured algae in Fujian Province.In order to further promote the cultivation of B.fuscopurpurea and solve the industrial problems of high impurities and rotten food existing in traditional raft cultivation,we conducted the cultivation mode of suspension propagation in kelp phytotron glass room with temperature 9.0~22.0℃during the period from December 9,2021 to February 10,2022.The results showed that the maximum average daily growth rate could reach 18.18%·d^(-1)and 21.39%·d^(-1)in the 50 L film bag air-lift photobioreactor and 1000 L culture tank,respectively,which the yield was much higher than that in indoor cement pond culture and marine raft culture.Ash content and crude fat separately increased by 20.81%and 25.00%,protein content decreased by 18.15%compared with raft net curtain cultivation,at the same time,the quality of unsaturated fatty acids was also better than that the latter.Land-based suspension propagation aquaculture could effectively avoid the problem of impurity pollution in marine aquaculture which was of great value to improve the processing efficiency and quality of B.fuscopurpurea.In this paper,we reported the land-based aquaculture of B.fuscopurpurea for the first time,which will provide new models and technologies for the facility aquaculture of macroalgae.
