We retrieved data from various studies to investigate the consequences of insect meal production and insect meal-based diets with respect to their environmental impact, including global warming potential, energy use, land use, water use, acidification, eutrophication as well as to economic fish-in fish-out ratio and solid waste output production. Analysis indicated that insect meals’ production exerted positive effects on land use but was associated with greater energy use and a larger carbon footprint compared to conventional protein sources. Substitution of silkworm meal (Bombyx mori) meals for fishmeal in aquatic animal diets significantly reduced solid phosphorus waste compared to insect-free diets. In contrast, the inclusion of black soldier fly (Hermetia illucens), housefly (Musca domestica), mealworm (Tenebrio molitor) and grasshopper (Zonocerus variegatus) has led, in comparison to insect-free diet, to greater solid nitrogen waste. Reducing the proportion of fishmeal and, to a lesser extent fish oil, by various insect meals in aquatic diet formulations significantly reduces economic fish-in fish-out, indicating less marine forage fish required per unit fish yield. The simulated data showed environmental benefit associated with land use of insect-containing aquafeeds compared to insect meal-free feeds, especially insect species of M. domestica and T. molitor. In all, this study suggested a trade-off of using insect meal as an aquafeed ingredient regarding environmental consequence. Since insect meal has excellent potential to supply protein for aquafeeds in the coming years, improvement in insect meal production systems and nutritional composition will be essential to make insect meal a sustainable aquafeed ingredient.

使用昆虫粉作为水产饲料成分的环境后果：系统观点

我们从各种研究中检索数据，以调查昆虫粉生产和以昆虫粉为基础的饮食对其环境影响的后果，包括全球变暖潜力、能源使用、土地利用、用水、酸化、富营养化以及经济鱼类- 淘汰率和固体废物产量。分析表明，与传统蛋白质来源相比，昆虫粉的生产对土地利用产生积极影响，但与更多的能源使用和更大的碳足迹有关。与无昆虫日粮相比，在水产动物日粮中用蚕粉 ( Bombyx mori ) 粉替代鱼粉可显着减少固体磷废物。相比之下，黑水虻（ Hermetia illucens）、家蝇（与无昆虫饮食相比，家蝇 ( Musca domestica )、黄粉虫 ( Tenebrio molitor ) 和蚱蜢 ( Zonocerus variegatus ) 导致了更多的固体氮废物。在水产饲料配方中通过各种昆虫粉减少鱼粉和鱼油的比例，在较小程度上减少鱼油的比例，显着减少了经济鱼入鱼出，表明每单位鱼产量所需的海洋饲料鱼更少。模拟数据显示，与不含昆虫粉的饲料相比，含昆虫水产饲料的土地利用带来的环境效益，尤其是M .  家养和T。 莫利托. 总之，这项研究提出了在环境后果方面使用昆虫粉作为水产饲料成分的权衡。由于昆虫粉在未来几年内具有为水产饲料供应蛋白质的巨大潜力，因此改进昆虫粉生产系统和营养成分对于使昆虫粉成为可持续的水产饲料成分至关重要。
