“…Although essential amino acid composition of the fillets remained unchanged, in the present study, juvenile flounders that were fed diets containing increasing amounts of CR at the expense of FM become increasingly enriched with CR‐associated fatty acids, such as C18:1 n − 9 and C18:2 n − 6, at the expense of beneficial n − 3 LC‐PUFAs, which may have unfavorable impacts on consumer health. The results obtained in the present study are in line with previous studies showing that replacing high levels of FM with insect meal negatively affects the composition and nutritional value of the fillet lipid fraction in various freshwater and marine fish species (Belforti et al, 2015; Iaconisi et al, 2017; Renna et al, 2017; Sánchez‐Muros, Barroso, & de Haro, 2016; Sánchez‐Muros, de Haro, et al, 2016; Sankian et al, 2018). However, given the insect's dietary flexibility, such drawback can easily be addressed by feeding the insects with n − 3 LC‐PUFA‐rich feed stuff, like fish offal, prior to being offered to the fish (Dossey et al, 2016; Sealey et al, 2011).…”

An 8‐week feeding trial was designed to evaluate the potential of cricket meal, Gryllus bimaculatus, as a locally available unconventional source of protein in a practical diet for olive flounder, Paralichthys olivaceus. Three hundred juvenile fish (Initial weight, 33.5 ± 0.01 g) were randomly distributed into five dietary groups in triplicates (20 fish per tank) and each group was hand‐fed one of the experimental diets containing graded level of a cricket meal (CR) replacing 0, 20, 40, 60, and 80% of fish meal (FM) protein (designated as CR0, CR20, CR40, CR60, and CR80). Although replacing more than 40% of dietary FM protein resulted in lower growth rates and feed utilization efficiency, juvenile flounders fed the highest level of dietary CR (CR80) still performed as well as control group (CR0). Replacing more than 20% of FM with CR markedly reduced apparent nutrient digestibility in fish. Plasma total cholesterol concentration showed decreasing trend with increasing inclusion levels of CR in the diet. Whole body and fillet lipid content decreased with increasing levels of dietary CR. There was a remarkable enhancement in the levels of C18 fatty acids and reduction in the levels of n − 3 highly unsaturated fatty acids in the fillets of fish fed with the CR diets, which became more prominent with greater levels of dietary FM replacement. Antioxidant enzyme activities tended to increase with increasing dietary CR levels but gradually decreased when the replacement level exceeded 60%. Overall, the efficiency of CR as a promising substitute for FM in the flounder diets has been confirmed not only in relation to growth rates, but also in terms of immunopotency.

Edible insects have become popular in the past few years not only in the scientific literature but in other media as well. One of the major advantages of entomophagy (eating insects) is said to be the great nutritional composition. Many sources report that insects (generally) have better nutritional characteristics than traditional protein sources. In our research, we aim to give a complete picture of the nutritional profile of insects using a multicriteria optimization method, sum of ranking differences. The materials we used are published results of different authors from the past few years. The proximate analysis tells that insects generally have a better nutritional profile than other meats. The situation is a bit different in the case of mineral content; hence some vegetables have excellent mineral sources but waxworm larvae were ranked in the first three. Additionally, waxworm larvae have the most similar amino acid pattern to the FAO recommendation for adults. Earthworm, house cricket, and mealworm larvae showed the most promising vitamin content; however, huge differences were observed between the developmental stages of insects. A detailed analysis of these differences on the example of mealworms showed that adults may present a better option from the nutritional point of view. Same measurements conducted by different authors on the same species show considerable differences; hence the comparison of the results of different publications is dubious and should be handled with care. Based on our results, insects have a promising nutritional profile and may become part of many food products in the future. Present status of knowledge allows to conclude; which insect is best suitable for human consumption.

“…The composition is related to the species and can be modulated through the rearing substrate [10,11,12]. In addition to nutrients, a crucial aspect to consider for the suitability of an insect species for feed purposes is the possibility of being mass-reared to deliver large quantities to the market at an affordable price [13,14,15,16]. The mass rearing of insects requires the development of artificial diets that are able to meet nutritional requirements and to guarantee good insect-rearing performance.…”

The black soldier fly (BSF; Hermetia illucens L.) is a very promising insect species due to the ability to convert low-value substrates in highly nutrient feed. This work aimed to study the effect of three nominally isoenergetic diets containing plant ingredients such as barley, alfalfa, and wheat byproducts, formulated to be higher in nonfiber carbohydrates (TMD1), fibers (TMD2), and protein (TMD3) in comparison to an extensively genetic modified cereal (cornmeal)-based diet (C), on the growth, yield, and nutritive traits of BSF prepupae (BSFPs). Three growing trials with four biological replicates were carried out. Proximate and fatty acid analyses were performed on the diets and BSFPs. Feed conversion ratios (FCR), dry matter and nutrient yields, and apparent concentration factors (aBCF) for fatty acids (FAs) were calculated. Diet formulation had a substantial effect on the survival, development rate, and larval yield, but the FCR was unaffected. The BSFPs fed TMD3 did not result in a higher crude protein content in comparison to the C or TMD2 diets. Despite the leveled fat content of the diets, BSFPs reared on TMD1 were highest in fat, saturated FA, and fat yield. An apparent bioconcentration factor (aBCF) value lower than unity that was found for the unsaturated FA suggests that the BSFPs inefficiently absorb them from the diet or possibly turn them into saturated FA. However, the unsaturated FA accumulation in BSFPs depended on the levels that were found in the diet, which suggested some possibilities for the FA profile modulation. Overall, the TMD2 performed well despite the low-value of its main ingredients and high fiber content and can be considered to be a feasible option for the mass rearing of BSFPs that are intended for animal feed.
