Black soldier fly (BSF, ) larvae is a prominent ingredient in aquafeeds due to its high protein and energy contents. This study evaluated the digestibility of full-fat BSF larvae meal (FF-BSFL) and its inclusion in diets for tambaqui, . The apparent digestibility coefficient of FF-BSFL for protein and energy was around of 88%, corresponding to 33.55% and 21.61 MJ kg of digestible protein and energy, respectively. For the feeding trial, tambaqui juveniles (53.23 ± 1.07 g) were distributed in a completely randomized experimental design (n = 4; 150 L tanks; 10 fish per tank). Fish were fed diets including 0%, 5.25%, 10.50%, and 15.75% FF-BSFL to apparent satiation for 60 days. Fish fed 10.50% FF-BSFL dietary inclusion showed higher weight gain, feed intake, final biomass, and relative growth rate. The 10.50% FF-BSFL diet presented the highest index of economic profitability. Weight gain fitted a third-degree equation and the optimum FF-BSFL inclusion level was estimated at 11.6%. However, FF-BSFL dietary inclusion up to 15.75% did not impair growth fish performance. FF-BSFL seems to be a promising source of protein and energy for omnivorous fish aquafeed.
黑水虻幼虫因其高蛋白和高能量含量，成为水产饲料中的一种重要成分。本研究评估了全脂黑水虻幼虫粉（FF-BSFL）的消化率及其在 tambaqui 日粮中的添加情况。FF-BSFL 中蛋白质和能量的表观消化系数约为 88%，分别相当于每千克可消化蛋白质 33.55%和每千克可消化能量 21.61 兆焦。在饲养试验中，将 tambaqui 幼鱼（53.23 ± 1.07 克）按照完全随机实验设计进行分配（n = 4；150 升水箱；每个水箱 10 条鱼）。给鱼投喂包含 0%、5.25%、10.50%和 15.75% FF-BSFL 的日粮，投喂至明显饱足状态，持续 60 天。日粮中添加 10.50% FF-BSFL 的鱼表现出更高的体重增加、采食量、最终生物量和相对生长率。10.50% FF-BSFL 的日粮呈现出最高的经济盈利能力指数。体重增加符合三次方程，估计 FF-BSFL 的最佳添加水平为 11.6%。然而，日粮中 FF-BSFL 添加量高达 15.75%并不会损害鱼的生长性能。FF-BSFL 似乎是杂食性鱼类水产饲料中一种很有前景的蛋白质和能量来源。
