The nutritional value of spirulina in aquafeeds has been studied extensively as a fishmeal replacer or as a functional feed additive to increase growth and health performance of fish in the last decade. Despite increased interest in spirulina research in aquaculture, its increased production cost still limits its use in commercial rations. Zarrouk’s medium is the standard substrate used for growing spirulina. Although this medium offers optimal biomass production, it incurs higher costs due to the expensive components needed for concocting the medium. In this regard, development of cost‐effective alternative culture medium or techniques is necessary for the industrial‐scale production of these microalgae. This paper reviews research on different alternative media for spirulina cultivation and its nutritive value as an aquafeed. Numerous alterations in the composition of Zarrouk’s medium with cheaper chemical ingredients have been explored as a potential substitute for cost‐effective microalgae cultivation. Industrial and processing wastes and by‐products with appropriate nutrient profiles for growing spirulina are also being considered as alternative culture media. The use of rice bran or other cheaper agricultural by‐products, as a cost‐effective growth medium for commercial‐scale spirulina production has yet to be explored extensively in agriculture‐based countries, especially in rice‐producing Asian countries.

螺旋藻研究综述：水产养殖的替代培养基和营养价值

在过去的十年中，螺旋藻在水产饲料中的营养价值已被广泛研究用作鱼粉替代品或功能性饲料添加剂，以提高鱼类的生长和健康表现。尽管对水产养殖中螺旋藻研究的兴趣增加，但其生产成本增加仍然限制了其在商业口粮中的使用。Zarrouk的培养基是用于种植螺旋藻的标准底物。尽管这种培养基提供了最佳的生物量生产，但由于配制该培养基所需的昂贵成分，导致成本较高。在这方面，对于这些微藻的工业规模生产，必须开发具有成本效益的替代培养基或技术。本文综述了螺旋藻栽培的不同替代培养基的研究及其作为水产饲料的营养价值。Zarrouk培养基的组成发生了许多变化，其中化学成分更便宜，已被认为可以替代具有成本效益的微藻。具有适当营养成分的螺旋藻生长的工业和加工废物及副产品也被视为替代培养基。在以农业为基础的国家，特别是在亚洲以大米生产的国家，尚未广泛探索将米糠或其他较便宜的农业副产品用作商业规模螺旋藻生产的经济有效的增长媒介。营养和营养成分适合螺旋藻生长的工业和加工废物及副产品也被视为替代培养基。在以农业为基础的国家，特别是在亚洲以大米生产的国家，尚未广泛探索将米糠或其他较便宜的农业副产品用作商业规模螺旋藻生产的经济有效的增长媒介。营养和营养成分适合螺旋藻生长的工业和加工废物及副产品也被视为替代培养基。在以农业为基础的国家，特别是在亚洲以大米生产的国家，尚未广泛探索将米糠或其他较便宜的农业副产品用作商业规模螺旋藻生产的经济有效的增长媒介。
