“…Almost all insect meals are considered low in lysine and tryptophan, with TM also being limited in sulfur amino acids [13]. The absence of any adverse effects on fish growth observed in our study could also be related to the fact that all the experimental diets were supplemented with some EAA (L-Arginine, L-Lysine, L-Tryptophan and DL-methionine) in order to allow the EAA requirements of rainbow trout to be fully met.…”

“…TM is considered a good alternative ingredient for the partial replacement of FM in the diets of several fish species [14,15,18,20]. However, high dietary inclusion levels (usually higher than 25%-30%) have been reported to negatively affect fish performance, usually due to a deficiency of some nutrients, such as some EAAs [7,13]. Unlike the results found in the literature, the results of the present study reveal that the inclusion of TM in rainbow trout diets did not affect either the fish growth performance or feed utilization for any of the considered inclusion levels.…”

“…It is a worldwide distributed beetle; and its larvae can easily be reared on low-nutritive plants and can efficiently convert food waste and agricultural by-products into high-quality biomass [12]. They are rich in proteins (44.1%-60.3% on a dry matter (DM) basis) and lipids (16.6%-43.1% DM) and their AA and FA profiles make them suitable for their inclusion in animal feeds [13].…”

Insect meals are good candidates to replace fishmeal as new protein sources in aquafeeds. This study evaluated the effects of fishmeal replacement with different dietary inclusion levels of a partially defatted Tenebrio molitor (L.) larva meal (TM) on rainbow trout (Oncorhynchus mykiss Walbaum) growth, diet digestibility, and hepatic intermediary metabolism. A 154-day growth trial was performed with 252 rainbow trout (78.3 ± 6.24 g) randomly divided into twelve tanks and fed four experimental diets containing increasing levels of TM: 0% (TM0), 25% (TM25), 50% (TM50), and 100% (TM100) of fishmeal substitution, corresponding to TM dietary inclusion levels of 0%, 5%, 10%, and 20%, respectively. A digestibility trial was performed feeding 180 rainbow trout (94.6 ± 7.31 g) with the experimental diets used in the growth trial. The growth parameters were not affected by TM dietary inclusion. Regarding the evaluated apparent digestibility coefficients (ADC), only the ADC of crude protein was affected, showing the following trend: TM0 = TM25 > TM50 > TM100. The activities of key hepatic amino acid catabolic and lipogenic enzymes were not affected by the dietary composition. The results suggest that a partially defatted TM could totally replace fishmeal in commercial rainbow trout diets without negative effects on fish performance.

“…From an environmental viewpoint, the huge amount of fish meal (FM), fish oil, and other marine protein sources in fish feed is a pivotal problem [5,6], because there are not enough currently existing oceanic resources to produce the fish feed needed to satisfy the continuously increasing global aquaculture production [6]. From an economic viewpoint, the increase of the global feed price, mainly caused by the increasing fish demand, has made the cost of feed a primary, industry-wide concern [1].…”

The Introduction of Insect Meal into Fish Diet: The First Economic Analysis on European Sea Bass Farming

The economic and environmental sustainability of aquaculture depends significantly on the nature and quality of the fish feed used. One of the main criticisms of aquaculture is the need to use significant amounts of fish meal, and other marine protein sources, in such feed. Unfortunately, the availability of the oceanic resources, typically used to produce fish feed, cannot be utilized indefinitely to cover the worldwide feed demand caused by ever-increasing aquaculture production. In light of these considerations, this study estimates how aquaculture farm economic outcomes can change by introducing insect meal into the diet of cultivated fish. Several possible economic effects are simulated, based on various scenarios, with different percentages of insect flour in the feed and varying meal prices using a case study of a specialized off-shore sea bass farm in Italy. The findings indicate that the introduction of insect meal—composed of Tenebrio molitor—would increase feeding costs due to the high market prices of this flour and its less convenient feed conversion ratio than that of fish meal. Therefore, the expected environmental benefits of using this highly promising insect meal in fish feed do not align with the current economic interests of the aquaculture industry. To our knowledge, this is the first study to investigate this theme, and it must be noted that our findings cannot be generalized widely because a specific case study was used. Nevertheless, our findings suggest that efforts should be made—at least at the farm level—to find profitable ways to encourage the introduction of this attractive alternative to guarantee both economic and environmental sustainability in the near future.

“…Nevertheless, recently, A. diaperinus was included in the list of insect species that are allowed to be used for the production of insect meal as aquafeed ingredient (Commission Regulation (EU) 2017/893; Gasco et al . ), changing our perspective on this insect from a noxious pest to a potential nutrient source.…”

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.
