“…In particular, the use of VP may cause morphological alterations capable of affecting the optimal nutrient absorption [6,55]. However, the effects of VP usually vary on varying the species, the protein source, and the level of inclusion [35,[56][57][58]. Based on the authors' knowledge, the effects of VP on the liver and gut histology of sturgeon have been only characterized by Kittel et al [59].…”

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.

“…Several effective methods were conducted to overcome the antinutritional effect of SBM in aquaculture, including deceasing its content in diets (Bonvini et al, ), or supplementation with methionine and phosphate (Kokou et al, ), phosphorus and magnesium (Imanpoor & Bagheri, ), glutamine and arginine (Gu et al, ), lysine and methionine (Jiang et al, ), hydrolysed feather meal (Zhang et al, ), exogenous enzyme complex (Ramos et al, ), mannan oligosaccharides (MOS) (Torrecillas et al, ) or lactoferrin (Ulloa et al, ) in diets with SBM. Scientists were also looking for other plant protein sources, such as cottonseed meal (CSM) (Lee, Dabrowski, Blom, Bai, & Stromberg, ), chickpeas meal (CPM) (Christodoulou et al, ), extruded canola seed‐pea (ECSP) (Bandegan et al, ), rubber seed meal (RSM) (Deng, Mai, Chen, Mi, & Zhang, ) or fermented Jatropha kernel meal (FJKM) (Phulia et al, ) to partially or totally replace SBM in aquafeeds.…”

Extruded soybean meal (ESBM) showed increased digestibility of crude protein, amino acids and fat, better oil retention capacities, attenuated anti‐nutrient factor effects and improved its nutritive value compared with raw soybean meal, indicating a promising application prospects for ESBM in fish culture. This study aimed to evaluate the effects of substituting fishmeal with ESBM on growth performance, hepatic antioxidant capacity and the resistance to hypoxia stress on juvenile Dolly Varden (Salvelinus malma). Five hundred and forty fish were randomly assigned to six groups fed with iso‐nitrogenous and iso‐energetic diets with ESBM for replacement of 0% (control), 10% (G1), 20% (G2), 30% (G3), 40% (G4) and 50% (G5) fishmeal. After an 81‐day feeding trial, groups fed ESBM substituted diets (G2 to G5) showed no significant differences in survival rates, final body weights, weight gain rates, feed conversion ratios, specific growth rates, hepatosomatic indexes and condition factors with the control group (G0), reflecting normal food intake and growth performance. The hepatic enzyme activities of total antioxidant capacity, catalase and superoxide dismutase were not affected by ESBM substituted diets, showing no harmful effects on ROS eliminating abilities. Hepatic HSP70 expression levels had increased 1.3 times for G5 group, reflecting a less tolerance to hypoxia for fish fed diets with high substituting level of ESBM. In conclusion, replacing, despite 50%, fishmeal with ESBM in diets had no detrimental effects on growth performance and hepatic enzyme activities, but lowering the hypoxia tolerance of juvenile Dolly Varden (Salvelinus malma).

“…When dietary lipid or energy exceeds the capacity of the hepatocytes to oxidize fat, the accumulation of lipid vacuoles occurs within the cells that dislocates the cell nucleus, a phenomenon known as steatosis, observed often in aquaculture species (Caballero et al, ; Fountoulaki et al, ; Kokou et al, ; Sitjà‐Bobadilla et al, ). Such an effect due to dietary imbalances can also occur in the intestine, with an accumulation of lipidic vacuoles within the enterocytes; this was observed in studies using plant meal‐based diets for gilthead seabream (Kokou et al, ; Sitjà‐Bobadilla et al, ) and different lipid sources for rainbow trout (Caballero et al, ). Similarly, in the shi drum intestine, an increase in the number of LV within the enterocytes was observed at dietary levels >150g/kg.…”

“…The gut sections were evaluated according to a semi‐quantitative method. The applied criteria in the present study were based on criteria used to assess the degree of SBM‐induced enteritis in the distal intestine of Atlantic salmon (Uran et al, ) and gilthead seabream as described by Kokou et al (). The chosen criteria were the following: (a) the appearance and length of the mucosal folds (MF); (b) the degree of infiltration and abundance of eosinophils (EP) into the lamina propria ; (c) the degree of widening of the lamina propria (LP); (d) the degree of widening of the submucosa (SM); and (e) the number of lipidic vacuoles (LV) within the enterocytes.…”

The shi drum, Umbrina cirrosa, is considered quite promising candidate and emerging alternative Mediterranean aquaculture species to the dominant, European seabass, Dicentrarchus labrax, and gilthead seabream, Sparus aurata, due to its high growth rate and feed efficiency (Segato, Corato, Fasolato, & Andrighetto, 2005). Shi drum feeds mainly on invertebrates and fish (Abellan & Basurco, ), suggesting that this species has high protein requirements. Moreover, the shi drum has a good adaptation capacity to culture conditions and, unlike the winter reproducers seabass and seabream, it is a spring-summer reproducer (Mylonas et al., 2004), thus providing a good species to grow in parallel with the existing cultivated species. Shi drum is a demersal fish, member of the Sciaenidae family (Nelson, Grande, & Wilson, 2016), living on the sandy bottom of maximum 100 m depth, and is distributed all around the Mediterranean Sea area, including the Black Sea. The size of the shi drum during catch is usually around 50-60 cm, but it can reach up to 1 m length and 12 kg weight (Mylonas et al., 2000a). In aquaculture settings, this species can achieve a weight of 500 g in only 15 months, which is near twice the growth rate of seabass and seabream (Fabi & Fiorentini, 1993; Mylonas et al., 2000b), thus making the shi drum a very attractive species for aquaculture. AbstractThe shi drum is an emerging Mediterranean aquaculture species that has gained increasing interest in recent years. However, the nutrient requirements of this species remain to be determined to optimize its culture. The present study evaluated the effects of dietary protein (470g/kg or 520g/kg) to lipid ratios (100g/kg, 150 or 200g/ kg) on the growth performance, nutrient utilization and tissue morphology of the shi drum (7 g average initial weight). Dietary protein levels positively correlated with weight gain, showing high protein demands (>470g/kg) for this species. Nonetheless, dietary lipid levels negatively affected growth rate, feed intake and efficiency, and protein utilization, suggesting that this macronutrient cannot be efficiently utilized in high concentrations (>100g/kg). Histological evaluation revealed fat accumulation within the hepatocytes and the enterocytes with increasing dietary lipid levels, starting from 150g/kg lipid inclusion. Overall, our results confirm the high dietary protein requirements of the shi drum (>470g/kg for fish of 7 g initial weight) and suggest that lipid levels should not exceed 100g/kg of inclusion in the diets as this species has a low tolerance to this macronutrient.
