“…Similarly, a previous study performed on gilthead sea bream (Sparus aurata L.) demonstrated that partial or total substitution of FM with a mixture of plant protein sources balanced with EAA did not modify the hepatic activity of AA catabolic enzymes [45]. Furthermore, a recent study performed by Guerreiro et al [46] observed that feeding meagre (Argyrosomus regius Asso) juveniles with increasing dietary levels of Hermetia illucens larva meal did not affect the activity of the hepatic amino acid catabolic enzymes.…”

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.

“…Therefore, in order to complete and support the previous results, this study aimed to assess the effect of partially replacing FM with HM on nutrient digestibility (using fish from the same batch of the ones used in the growth trial performed at Guerreiro et al. (2020)) and digestive enzyme activity (using fish from the growth trial) in meagre. Additionally, a characterization of the alkaline protease fraction of meagre intestine was performed.…”

“…Four experimental diets were formulated as described in Guerreiro et al. (2020). Shortly, a FM‐based diet was used as control (CTR diet), and three other diets were formulated to include 100, 200 and 300 g/kg of defatted HM (diets HM100, HM200 and HM300, respectively), replacing 17, 35 and 52% of FM, respectively.…”

“…Until now, H. illucens meal (HM) has been evaluated as a feed ingredient mainly in freshwater species; in marine fish, HM was only assessed in turbot ( Psetta maxima ), gilthead seabream ( Sparus aurata ), European sea bass ( Dicentrarchus labrax ), sea‐water phase Atlantic salmon ( Salmo salar ), Japanese sea bass ( Lateolabrax japonicus ) and meagre ( Argyrosomus regius ) (Belghit et al., 2019; Guerreiro et al., 2020; Karapanagiotidis et al., 2014; Kroeckel et al., 2012; Lock et al., 2016; Magalhães et al., 2017; Wang et al., 2019). Results showed that up to 45 and 100% of FM can be replaced by HM in diets for European sea bass and Atlantic salmon, respectively, without affecting nutrients’ apparent digestibility coefficients (ADCs) (Belghit et al., 2019; Magalhães et al., 2017).…”

The effect of partially replacing fishmeal (FM) by black soldier fly larvae meal (Hermetia meal—HM) in meagre (Argyrosomus regius) diet was evaluated for nutrient digestibility and digestive enzyme activity. For that purpose, triplicate groups of fish (18.0 ± 0.02 g) were fed during 48 days either a control diet (CTR), without HM, or one of three diets including 100, 200 and 300 g/kg of HM, replacing 17, 35 and 52% of FM, respectively. Apparent digestibility coefficients (ADCs) of dry matter, energy, protein, lysine, isoleucine, leucine, phenylalanine, alanine, glutamate, glycine and serine presented a decreasing response with increased HM inclusion. Chitin ADC was null, independent of dietary HM inclusion. Total alkaline protease activity increased while trypsin activity decreased with dietary HM inclusion. No intestinal chitinolytic activity was detected. Intestinal alkaline protease zymogram revealed nine bands with proteolytic activity against casein, with molecular weights ranging between 15 and 75 kDa. Anti‐protease activity in the intestine was not affected by dietary inclusion of HM compared to the CTR diet. Overall, it is concluded that replacement of up to 17% FM with HM (100 g/kg HM inclusion level) in meagre diets has no major adverse effects in diet digestibility and digestive enzyme activity.

“…In the last few years, the potential of IM as partial or complete replacer of FM has been investigated [15] with interesting results both in freshwater fish such as rainbow trout (Oncorhynchus mykiss) [16,17], Siberian sturgeon (Acipenser baerii) [18,19], Jian carp (Cyprinus carpio var. Jian) [20], Yellow catfish (Pelteobagrus fulvidraco) [21], Nile tilapia (Oreochromis niloticus) [22,23] North African catfish (Clarias gariepinus) [24] and mandarine fish (Siniperca scherzeri) [25], and marine fish, as in European seabass (Dicentrarchus labrax) [26,27], gilthead sea bream (Sparus aurata) [28], Japanese seabass (Lateolabrax japonicus) [29], Atlantic salmon (Salmo salar) [30][31][32], and meagre (Argyrosomus regius) [33].…”

The trial investigates if a highly defatted Hermetia illucens larva meal (H) at two dietary inclusion levels and a vegetable protein based diet (VEG) influences the normal gut and liver histology and the oxidative stress biomarkers in liver and kidney of Siberian sturgeon juveniles. Fish were fed four diets: one control diet (H0) containing 70% of fishmeal (FM), two diets including 18.5% (H185) and 37.5% (H375) of highly defatted H in substitution for 25% and 50% of FM, and one vegetable protein based diet (VEG). At the end of a growth trial, 12 fish per treatment were sacrificed by over-anaesthesia to collect 12 liver and 5 distal intestine samples for histological analyses, as well as 12 liver and kidney samples for biochemical analyses. The H and VEG diets did not significantly affect the histology of liver and distal intestine, but alterations of the oxidative stress biomarkers were detected at the highest inclusion level of H (37.5%). In order to avoid unfavorable effects on the fish health, an inclusion level up to 18.5% of H is recommended for Siberian sturgeon juveniles.
