Larvae of the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae), are voracious feeders of organic material and may thus be used in simple engineered systems to reduce organic waste in low- and middle-income countries. Controlled feeding experiments with standard fodder were conducted to assess the optimum amount of organic waste to be added to a CORS system (Conversion of Organic Refuse by Saprophages). A daily feeding rate of 100 mg chicken feed (60% moisture content) per larva resulted in an optimum trade-off between material reduction efficiency (41.8%, SE 0.61) and biomass production (prepupal dry weight: 48.0 mg, SE 2.0). Applied to market waste and human faeces, this corresponds to a potential daily feeding capacity of 3-5 kg/m(2) and 6.5 kg/m(2), respectively. In addition, H. illucens prepupae quality was assessed to determine their suitability to substitute fishmeal in animal feed production. The chitin-corrected crude protein content ranged from 28.2 to 42.5%, depending on the amount of food provided to the larvae. Based on our study, a waste processing unit could yield a daily prepupal biomass of 145 g (dry mass) per m(2). We conclude that larvae of the black soldier fly are potentially capable of converting large amounts of organic waste into protein-rich biomass to substitute fishmeal, thereby contributing to sustainable aquaculture.
黑水虻（Hermetia illucens，双翅目：水虻科）的幼虫是有机物质的贪婪食客，因此可用于简单的工程系统，以减少低收入和中等收入国家的有机废物。我们进行了使用标准饲料的对照喂养实验，以评估添加到CORS系统（腐食性生物转化有机垃圾系统）中的有机废物的最佳量。每只幼虫每天100毫克鸡饲料（含水量60%）的喂养率在物质减少效率（41.8%，标准误0.61）和生物量生产（预蛹干重：48.0毫克，标准误2.0）之间实现了最佳平衡。应用于市场垃圾和人类粪便时，这分别对应于3-5千克/平方米和6.5千克/平方米的潜在每日喂养能力。此外，还评估了黑水虻预蛹的质量，以确定它们在动物饲料生产中替代鱼粉的适用性。根据提供给幼虫的食物量，经几丁质校正的粗蛋白含量在28.2%至42.5%之间。基于我们的研究，一个废物处理单元每平方米每天可产生145克（干重）预蛹生物量。我们得出结论，黑水虻幼虫有潜力将大量有机废物转化为富含蛋白质的生物量以替代鱼粉，从而为可持续水产养殖做出贡献。
