Conventional open-sea cultivation constrained by environmental factors is singly incompetent to sustain the rising seaweed demand. This necessitates a complementary strategy to reinforce the existing cultivation system and expand the global seaweed industry. Present study proposes cultivation of Ulva lactuca in temperature controlled flat panel photobioreactors under natural illumination. Adaptability of U. lactuca to the flat panel system is apparent through growth studies and photosynthetic performance (F/F) across individual panels. Evident effect of annual variation in irradiance on daily growth rates, biomass productivity and composition is portrayed. Significance of initial stocking density and harvesting frequency is highlighted. Poultry litter extract was used as an alternative N-source for sustainable cultivation. The maximum achievable productivity was 303gmd (fresh weight) expanding to 910tonshayr including biomass composition consistent with the control media. The present pilot scale study delivers valuable information for commercial scale photobioreactors for seaweed cultivation.
传统的开放式海洋养殖受到环境因素的限制，无法满足不断增长的海藻需求。这就需要采取补充策略来加强现有的养殖系统并扩大全球海藻产业。本研究提出在自然光照下的温度控制平板光生物反应器中养殖浒苔。通过生长研究和各个平板的光合性能（F/F），可以明显看出浒苔对平板系统的适应性。描绘了光照强度的年际变化对日生长率、生物量生产力和组成的明显影响。强调了初始放养密度和收获频率的重要性。家禽粪便提取物被用作可持续养殖的替代 N 源。最大可实现的生产力为 303gmd（鲜重），扩展到 910tonshayr，包括与对照培养基一致的生物质组成。本试点规模研究为商业规模的海藻养殖光生物反应器提供了有价值的信息。
