Seaweed growth is often limited by light. Artificial light supply has been well studied in terrestrial agriculture, however, much less is known about its effect in seaweed aquaculture. In this study, the effects of four artificial light sources (white, red, green, and blue LEDs light) on a brown alga and a green alga were investigated Seaweed growth, accumulation of photosynthetic pigments (chlorophyll and carotenoid), and soluble protein were evaluated. White LED light was the optimal supplementary light when cultivating and , because it promoted seaweed growth while maintaining protein production. Meanwhile, red LED was unfavored in the cultivation of , as it affected the seaweed growth and has a lower residual energy ratio underneath the water. LEDs would be a promising supplementary light source for seaweed cultivation.
海藻的生长常常受到光照的限制。人工光照供应在陆地农业中已得到充分研究，然而，其在海藻养殖中的作用却鲜为人知。在本研究中，研究了四种人工光源（白色、红色、绿色和蓝色发光二极管灯）对一种褐藻和一种绿藻的影响。评估了海藻的生长、光合色素（叶绿素和类胡萝卜素）的积累以及可溶性蛋白质。在培养[褐藻名称]和[绿藻名称]时，白色发光二极管灯是最佳的补充光源，因为它在促进海藻生长的同时还能维持蛋白质产量。同时，红色发光二极管灯不利于[绿藻名称]的培养，因为它影响海藻生长且在水下的剩余能量比更低。发光二极管将是一种很有前景的海藻养殖补充光源。
