“…As reviewed above, δ 13 C AA values could detect whether salmon fed on aquafeed containing milled seaweed ingredients (15% seaweed substituted the caloric equivalent of fishmeal and corn starch) (Wang et al, 2018b). Likewise, in a feeding trial with black soldier flies reared for aquafeed, the δ 13 C AA method could detect whether the flies had fed on diets spiked with non-permitted bovine blood residues (Belghit et al, 2021). This is a remarkable result because the flies were fed a control diet for 7 days after initially being fed a diet with 10% (w/w) bovine blood residues.…”

“…However, both legacy and novel authentication methods displayed shortcomings. Hence, to detect particular contaminants or ingredients across two trophic levels Belghit et al (2021) recommended a tiered combined use of complementary approaches.…”

“…While molecular methods (e.g., DNA quantification and targeted metabolite profiling) are suited for characterizing aquafeed ingredients before or right after ingestion, stable isotope analyses of animal tissues are usually employed to characterize ingredients after their nutrients have been absorbed (Belghit et al, 2021;Gamboa-Delgado, 2022). The stable isotope values of total organic carbon (bulk δ 13 C), the most commonly analyzed element, have been used successfully for food authentication and tracing aquaculture ingredients (Molkentin et al, 2007;Anderson et al, 2010;Hassoun et al, 2020).…”

“…Recently, stable isotope analysis in single AAs has shown considerable more precision in discerning among algae and other novel functional feed additives within test aquafeed composites (Wang et al, 2018b(Wang et al, , 2019Belghit et al, 2021;Xu et al, 2021). In terms of nutritional requirements, the 20 proteogenic AAs can be divided into two functional classes: the essential and the FIGURE 1 | Schematic presentation of seaweed inclusion in compound feeds containing plant and fish derived ingredients for a carnivorous fish.…”

To meet future seafood demands, ingredients derived from algae and other novel and sustainable sources are increasingly being tested and used as replacers to traditional aquafeed ingredients. Algal ingredients in particular are being promoted for their sustainability and their additional functional attributes in farmed aquatic animals. Test on algal supplemented aquafeeds typically focus on a suite of immunological and physiological indicators along with fish growth performance or muscle quality. However, to optimize the replacement of fish meal with algal derived ingredients, it is crucial to understand the metabolic fate in the algal macronutrients (carbohydrates, fats, and proteins), and their nutritional interactions with other ingredients after ingestion. Here, we assess the potential of using the emerging technology- stable carbon isotope (δ13C) analysis of single amino acids (AAs) as a nutritional biomarker in aquaculture. Applications of δ13CAA-based approaches in feeding trials show promise in closing the knowledge gap in terms of understanding how fish and other aquaculture taxa assimilate and metabolize algal derived macronutrients. Source diagnostic δ13C fingerprints among the essential AAs can trace the protein origins to broad phylogenetic groups such as red macroalgae, brown macroalgae, bacteria, and terrestrial plants. Among the non-essential AAs, δ13C patterns have the potential to inform about metabolic routing and utilization of dietary lipids and carbohydrates. Despite the potential of δ13CAA as a nutritional biomarker, the few applications to date in fish feeding trials warrant further development and implementation of δ13CAA-based approaches to improve understanding of protein origins and macronutrient metabolic routing.

“…In fact, they can be a major contributor to the easing of legislation. For example, Belghit et al (2021) proposed a molecular method for improved detection, differentiation and tracing of prohibited material in processed animal proteins (PAPs) derived from insects in feed chains. This may contribute to lifting the feed ban rules as the transmissible spongiform encephalopathy regulation in the EU prohibits the use of PAPs derived from insect in feed for pigs and poultry.…”

An overview is given of the special issue on edible insects covering a number of aspects along the value change. The articles presented cover topics about producing insects both as food for humans and feed for animals, ranging from environmental impact, facility design, (left-over) substrates, the role of microbes, genetics, diseases, nutrition, to insect welfare. Possible health benefits of insects for humans and animals are discussed as well as the potential dangers in terms of allergies and chemical/biological contaminants. Regulatory frameworks are examined and assessed for remaining obstacles. The technologies dealing with the processing and extraction of proteins, lipids, and chitin were also reviewed. Consumers’ perception of insect-derived food products is discussed as well. A unique aspect of this special issue within the ‘Journal of Insects as Food and Feed’ is a first attempt to discuss the economics of the industry. The special issue concludes with a discussion of policy and challenges facing the sector.
