“…IMs are known for causing varied effects on the immunological system of fish, while the precise mechanisms that produce them are still unknown [ 14 , 30 , 33 , 88 ]. In general, the immunostimulant effect of Ims is well accepted [ 30 , 101 , 102 ], and a frequent justification for this is the influence of chitin and its derivatives, together with the presence of antimicrobial peptides in insects [ 13 , 103 ]. However, a publication by Xu [ 104 ] described how the replacement of soybean oil with an ω-3 enriched insect oil modified the genetic expression of IL-1β, IL-10, and TNF-α on the liver and kidney of juvenile mirror carp, as well as the amount of serum lysozyme.…”

“…Because the immunological system is complex and multifactorial, the different components of IMs such as chitin, insect fat, or other that might not be considered, could lead to very different interactions with it. Even though these immunological benefits are usually attributed to IMs, its chitin, or both [ 30 , 101 ], concluding results will not be reached until the precise mechanisms involved are described.…”

The demand of optimal protein for human consumption is growing. The Food and Agriculture Organization (FAO) has highlighted aquaculture as one of the most promising alternatives for this protein supply gap due to the high efficiency of fish growth. However, aquaculture has been facing its own sustainability problem, because its high demand for protein has been traditionally satisfied with the use of fishmeal (FM) as the main source. Some of the most promising and sustainable protein substitutes for FM come from insects. The present manuscript provides insight into an experiment carried out on rainbow trout (Oncorhynchus mykiss) with a 50% replacement of FM with different larvae insect meals: Hermetia illucens (HI), and Tenebrio molitor (TM). TM showed better results for growth, protein utilization and more active digestive function, supported by intestinal histological changes. Liver histology and intermediary metabolism did not show relevant changes between insect meals, while other parameters such as antioxidant enzyme activities and tissue damage indicators showed the potential of insect meals as functional ingredients.

“…Particularly, apart from being a high protein source, Z. morio meal contains adequate quantities of the most limiting amino acids in fish diets, i.e., lysine, threonine, and arginine, with the exception of methionine, in which it is deficient ( Table 2 ). In a recent study, 15 and 30% dietary inclusion of full-fat Z. morio larvae meal in replacement of soybean meal and soybean oil did not impact the survival and growth performance of Nile tilapia [( Oreochromis niloticus (L.)] juveniles ( Alves et al 2020 ). However, in the same study, the fish body composition was altered by insect meal inclusion, as fish fed on the diets containing 30% Z. morio meal had higher moisture and lipid contents and lower ash and protein contents, as compared with fish that were fed on the control diet.…”

Moreover, the inclusion of Z. morio in aquafeeds may positively influence several innate immunity parameters ( Alves et al 2020 ). Regarding the digestibility of Z. morio meal, Fontes et al (2019) assessed the nutrient and energy apparent digestibility coefficients (ADCs) from a Z. morio -based diet at a 20% inclusion level for Nile tilapia.…”

The aim of this review is to compile up-to-date information on the superworm, Zophobas morio (F.), regarding its biology and ecology, but also its further potential for use as a nutrient source for food and feed. We illustrate certain basic characteristics of the morphology and bio-ecology of this species, which is marginally considered as a ‘pest’ in durable amylaceous commodities. More recent data show that Z. morio can be a valuable nutrient and antimicrobial source that could be utilized further in insect-based feed and food production. The inclusion of this species in aquafeed has provided promising results in a wide range of feeding trials, both in terms of fish development and health. Additional data illustrate its potential for use in poultry, indicating that this species provides comparable results with those of other insect species that are used in feed. Moreover, Z. morio can be a viable waste management agent. This review aims to summarize the available data and underline data gaps for future research, toward the potential of the utilization of Z. morio for human food and animal feed. Based on the data presented, Z. morio appears to be a well-promising insect-based protein source, which potential still remains to be unfold.

“…Furthermore, according to Clark et al (1993) method (Reissig et al, 1955). This method was adopted by Alves et al (2020) for estimating the chitin content. Also, studies conducted by Marono et al (2015) calculated chitin considering the protein linked to acid detergent fibre (AOAC, 2003).…”

A major challenge for development of sustainable aquafeeds is its dependence on fish meal and fish oil. Similarly, it is unwanted to include more plant ingredients which adds more pressure on resources like arable land, freshwater and fertilisers. New ingredients that do not require these resources but rather refine and valorise organic side streams, like insects, are being developed. Increasing evidence indicates that using insect ingredients in aquafeeds are a sustainable alternative and considerable progress has been made on this topic in the past years. The aim of this chapter is to present a comprehensive and systematic analysis of the data available on the impact of insects in aquafeeds. Systematic search, collection and selection of relevant literature from databases such as Web of Science and NCBI was performed. The literature search enabled 91 scientific papers from peer-reviewed journals, comprising a dataset of 415 experimental diets, including 35 different aquatic species and 14 insect species to be included in this meta-analysis, covering what we consider a close to complete representation of credible publications on this topic. Information on aquatic species, insect species, dietary composition (amino acids, fatty acids, proximate composition) and performance outputs (growth performance indicators and nutrient digestibility) were included in the construction of the dataset. Regression models and principal component analyses were performed on the meta-data. The results from the meta-analysis revealed a great degree of variation in the maximum threshold for insect inclusion in aquafeeds (from 4 to 37%) based on subgroups of trophic level of aquatic species, insect species used, statistical method and the output parameter. Overall, a maximum threshold of 25-30% inclusion of insects in aquafeeds for uncompromised performance is suggested. Reduction in protein digestibility, imbalanced amino acid profile and increasing levels of saturated fatty acid were identified as major factors limiting higher inclusion of insects in aquafeeds.
