“…Insects have been proposed as an efficient and high-quality alternative protein source for poultry [ 37 , 38 ], swine [ 11 , 39 ] and carnivorous fish [ 13 , 15 , 16 , 17 , 20 , 40 ] and interest in use of insect meals in perch diets is high. Insects are a viable source of protein and lipids [ 9 , 10 ] and a typical component of Eurasian perch natural diet. Nogales-Mérida [ 9 ], confirmed insects as an excellent source of several vitamins and minerals including iron, potassium, calcium and magnesium.…”

“…Recently, interest has turned to PAPs from insects as a component of aquafeeds [ 9 , 10 ]. Insect larva meals are rich in proteins and their EAA profile is close to that of FM and considered superior to that of plant proteins [ 9 ]. The use of insect PAP has recently been sanctioned by the European Commission (Brussels, Belgium) (Regulation 2017/893/EC, 2017).…”

Insect meal is gaining increased attention in aquafeed formulations due to high protein content and an essential amino acid profile similar to that of fishmeal. To investigate insect meal in feed for European perch Perca fluviatilis, a promising candidate for European intensive culture, we replaced standard fishmeal with partially defatted black soldier fly Hermetia illucens larva meal at rates of 0%, 20%, 40% and 60% (groups CON, H20, H40 and H60, respectively) and compared growth performance, somatic indices, hematological parameters, whole-body proximate composition and occurrence of spleen lipidosis. In addition, we assessed the economic and environmental sustainability of the tested feeds by calculating economic conversion ratio (ECR) and economic profit index (EPI). The tested groups did not differ in survival rate. Significant differences were documented in final body weight and specific growth rate, with the highest values in CON, H20 and H40. The proximate composition of fish whole-body at the end of the experiment did not differ in dry matter, crude protein or ether extract, while organic matter, ash and gross energy composition showed significant differences. The fatty acid content and n-3/n-6 ratio showed a decreasing trend with increasing H. illucens larva meal inclusion. No differences were found in hematological parameters among tested groups. The H. illucens larva meal inclusion significantly affected ECR and EPI, even at 20% inclusion level the cost of diets did not differ from the control fish meal based diet. Results suggested that 40% inclusion of H. illucens larva meal can be used successfully in standard diets for perch.

The lesser mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), is one of the most common insect pests in commercial poultry farms, where it reproduces within the litter floor, feeding on poultry manure, spilled feed and other organic material. It can also infest, feed and reproduce on stored grains and related amylaceous commodities. Its significance is related mostly with the fact that it serves as reservoir and vector for many pathogens that cause serious diseases, such as Salmonella, Escherichia and various viruses. Recently, A. diaperinus attracted a lot attention as it was listed in the EU Regulation 2017/893 among the insect species that are allowed to be used for the production of insect meal as aquafeed ingredient, changing our perspective on this insect from a noxious pest to a potential nutrient source. This is the first review on A. diaperinus summarizing the significant recent findings in its biology and control. Moreover, this review aims to provide a helpful tool for aquaculture scientists working with A. diaperinus as aquafeed ingredient. Therefore, we gather and highlight the available data that classify A. diaperinus as a promising insect-based protein provider and we comment and discuss on the public concerns that arise from its utilization as feed.

“…The interest of using insects in animal feed is increasing [35,36], and inclusion of BSFL have been investigated in diets for pigs [9], chicken [12] and sh [11,37], but to this date, there is limited information about the effect of high dietary inclusion levels. The present study demonstrated that up to 19.06% fullfat BSFL meal can be included as an alternative protein and energy source in pelleted diets for weaned piglets without affecting growth performance.…”

Background: Weaning is associated with growth decline and morphological changes in the gastrointestinal tract of the pig. Insects, such as the Black soldier fly larvae (BSFL), are suggested as a sustainable novel protein source in diets for pigs. They contain chitin, medium chained fatty acids, and anti-microbial peptides, which could improve the gastrointestinal function and health in the post-weaning pig. The objective of this study was therefore to investigate the effect of increasing inclusion of full-fat BSFL in diets for post-weaning pigs on growth performance parameters, digestibility, gut morphology, and the microbial community in the colon. Eighty crossbred weanling pigs were weaned at approximately 32 days of age, with an average weaning weight of 10.6 ± 0.8 kg. For four weeks, the pigs were fed one of four dietary treatments: a control diet or one of three diets containing an increasing amount of full-fat BSFL meal: 4.76% (BSFL5), 9.52% (BSFL10), and 19.06% (BSFL20). Results: Increased level of full-fat BSFL in the diet did not affect growth performance or fecal consistency. A reduction in apparent total tract digestibility (ATTD) of crude protein (P = 0.035) was found for increased inclusion of BSFL, whereas the ATTD of crude fat increased (P<0.001). Jejunal, ileal, or colonic morphometry was not affected by the BSFL inclusion. Some changes in the colon microbiota were observed, but no differences in the short-chain fatty acid concentrations were detected between the dietary treatments. At the phylum level, dietary treatment affected the relative abundance of Bacteroidota, Firmicutes, Campilobacteria, and Thermoplasmatota, but there was no clear pattern relationship with the BSFL inclusion level. At the genus level, the inclusion of BSFL in the diet reduced the relative abundance of Lactobacillus (P = 0.015) compared to the control. Conclusions: Collectively, the results indicate that up to 19.06% of full-fat BSFL meal could be included in a balanced diet for PW pigs without affecting growth performance, gut function, or health.
