The global shrimp processing industry generates substantial amounts of solid waste (head, abdominal exoskeleton, and tail), with a considerable part currently being disposed of in landfills. It holds significant potential as an alternative ingredient in aquaculture feed due to its relatively high crude protein content, balanced amino acid profile, and presence of bioactive compounds. However, one of the main challenges with shrimp processing waste is its rapid spoilage. Consequently, shrimp solid processing waste must undergo further refinement to produce shrimp‐derived products suitable as aquaculture feed ingredients, such as meal, hydrolysate, or silage. This literature review describes the nutritional value, applications, challenges, and prospects of these shrimp‐derived products in aquaculture feed. Among the investigated shrimp‐derived products, shrimp hydrolysate has the highest nutritional value considering the high crude protein content, balanced amino acid profile, low chitin content, and low ash content. However, producing shrimp hydrolysate requires extensive processing, which can be costly, limiting its applications to high‐value aquaculture species. On the other hand, shrimp meal and shrimp silage, which require less energy‐intensive processing, may be more suitable for lower‐value aquaculture species that naturally consume feeds high in ash and chitin. The prospects for using shrimp‐derived products in aquafeed are promising, with advances in processing technologies showing potential to reduce costs, improve nutritional value, and enhance product quality and safety. Ultimately, shrimp‐derived products could replace current aquafeed ingredients while simultaneously utilizing current shrimp solid waste streams, provided that quality and safety measures are carefully considered.

水产养殖饲料中的虾加工废物：营养价值、应用、挑战和前景


全球虾加工业产生大量固体废物（头部、腹部外骨骼和尾部），其中相当一部分目前被丢弃在垃圾填埋场。由于其相对较高的粗蛋白含量、平衡的氨基酸分布以及生物活性化合物的存在，它作为水产养殖饲料的替代成分具有巨大的潜力。然而，虾加工废物面临的主要挑战之一是其快速腐败。因此，虾固体加工废物必须经过进一步精炼，以生产适合作为水产养殖饲料成分的虾衍生产品，例如粗粉、水解产物或青贮饲料。本文献综述描述了这些虾源产品在水产养殖饲料中的营养价值、应用、挑战和前景。在所研究的虾衍生产品中，考虑到粗蛋白含量高、氨基酸分布均衡、甲壳素含量低和灰分含量低，虾水解物具有最高的营养价值。然而，生产虾水解物需要大量加工，成本高昂，限制了其在高价值水产养殖品种中的应用。另一方面，虾粉和虾青贮饲料需要较少的能源密集型加工，可能更适合天然消耗灰分和甲壳素含量高的饲料的低价值水产养殖品种。在水产饲料中使用虾源产品的前景广阔，加工技术的进步显示出降低成本、提高营养价值以及提高产品质量和安全性的潜力。 最终，如果仔细考虑质量和安全措施，虾衍生产品可以取代当前的水产饲料成分，同时利用当前的虾固体废物流。
