Abstract

The present study aimed to compare the growth performance and liver and muscle fatty acid (FA) profile of juvenile common carp fed with raw black soldier fly (BSFL; Hermetia illucens) and honey bee drone brood (BDB; Apis mellifera), a novel insect in aquaculture, with a commercial carp diet (CCF). After 6 weeks, the weight gain and specific growth rate were significantly higher in fish fed with CCF, followed by the BDB-fed and BSFL-fed fish, with significant differences among groups. The essential FA contents in feeds were disproportionally mirrored in fish livers and muscles, suggesting feed-dependant biosynthesis ability in common carp. In conclusion, the results suggest that dietary FAs affect the muscle FA composition of common carp. Yet, the composition of dietary essential FAs content did not mirror the essential FA content in muscle, confirming the biosynthesis of essential FAs. The BDB appeared to be a viable alternative or supplement to CCF compliant with circular bioeconomy without compromising the FA profile of common carp muscles. Despite the low growth performance of fish fed with BSFL, this diet indicated good nutritional qualities regarding the FA profiles.

用生黑刺苍蝇幼虫和蜜蜂无人机雏喂养鲤鱼的生长性能和脂肪酸谱图

本研究旨在比较用水产养殖中的一种新型昆虫--生黑兵蝇（BSFL；Hermetia illucens）和蜜蜂无花蜂蛹（BDB；Apis mellifera）与商品鲤鱼日粮（CCF）喂养鲤鱼幼鱼的生长性能、肝脏和肌肉脂肪酸（FA）谱。6周后，CCF饲料喂养的鱼增重和特定生长率明显高于BDB饲料喂养的鱼和BSFL饲料喂养的鱼，组间差异显著。饲料中必需脂肪酸的含量与鱼肝和肌肉中的含量不成比例，表明鲤鱼的生物合成能力取决于饲料。总之，研究结果表明，膳食中的脂肪酸会影响鲤鱼肌肉中的脂肪酸组成。然而，膳食中必需脂肪酸的含量并不反映肌肉中必需脂肪酸的含量，这证实了必需脂肪酸的生物合成。BDB似乎是符合循环生物经济的CCF的可行替代品或补充剂，同时不会影响鲤鱼肌肉的FA组成。尽管使用 BSFL 饲喂的鱼类生长性能较低，但这种饲料在脂肪酸谱方面显示出良好的营养品质。

期刊介绍： The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
