鱼类人工繁殖场和池塘养鱼场在培育幼鱼时,需要大量活饵料,尤其是小型活饵料。苏联的鱼类人工繁殖场一般都有培养寡毛纲环节动物和水蚤的设备,但产量低,成本高,不能满足养鱼业对活饵料的需要。苍蝇繁殖力强,幼虫生长快,可以用较小的面积在短期内生产出大量的蛆来。蛆的营养物质含量,不亚于其他作鱼类活饵料的无脊椎动物和动物性饵料。见下 Fish farms and pond fish farms require large amounts of live bait, especially small live bait, to breed juveniles. Fish farms in the Soviet Union generally have the equipment for culturing the animals of the genus Olivosus and daphnia, but the production is low and the cost is high, which can not meet the need of the fish farming for live feed.

Maggot nutrient content, no less than other fish live food for the invertebrates and animal feed. See below
