Insect meal could represent an option for partial replacement of fishmeal, the quantity and price of which are a constraint to the expansion of aquaculture. In this article, the acceptance of insect meal as a feed component among Italian farmers of trout and seabass is investigated and discussed. Semi‐structured interviews have been conducted with farmers, feed producers, and insect‐meal producers. Then, a deductive thematic analysis has been carried out to understand which of the different variables characterizing farming structures and marketing channels can affect the choice of feed products and, as a consequence, the acceptance of insect meals. The information collected suggests to differentiate two levels of insights: the first concerns plain economic evaluation in what could be considered a standardized or theoretical environment, and is mainly related to the feed price and the feed conversion ratio. The second level takes into consideration the effects that occur in real environments and that are different depending on farm characteristics and business choices. Among the main aspects that should be considered (beyond prices and feed conversion ratio) are the final destination of the product, the processing and large retailers' requirements, the effects on digestion and feces production, and the variability of performance (as an effect of feed nutritional variability and environmental variability).

在水产养殖饲料中接受虫粉:意大利鳟鱼和鲈鱼供应链的利益相关者分析
虫粉可能是部分替代鱼粉的一种选择,鱼粉的数量和价格限制了水产养殖的发展。在本文中,研究和讨论了意大利粉鳟鱼和鲈鱼养殖者对虫粉作为饲料成分的接受程度。对农民,饲料生产者和昆虫餐生产者进行了半结构化访谈。然后,进行了演绎主题分析,以了解表征农业结构和销售渠道的不同变量中的哪一个会影响饲料产品的选择,进而影响虫粉的接受度。收集到的信息建议区分两种不同的见解:第一种是在可以被视为标准或理论环境的情况下进行的简单经济评估,并且主要与饲料价格和饲料转化率有关。第二个级别考虑了在实际环境中发生的影响,这些影响会根据服务器场的特性和业务选择而有所不同。在应考虑的主要方面(价格和饲料转化率之外)是产品的最终目的地,加工和大型零售商的要求,对消化和粪便生产的影响以及性能的变化(作为饲料的影响)。饲料的营养变异性和环境变异性)。
