Evaluation of defatted black soldier fly (Hermetia illucens L.) larvae meal as an alternative protein ingredient for juvenile Japanese seabass (Lateolabrax japonicus) diets

Could Dietary Black Soldier Fly Meal Inclusion Affect the Liver and Intestinal Histological Traits and the Oxidative Stress Biomarkers of Siberian Sturgeon (Acipenser baerii) Juveniles?

“…In the present study, no significant differences were observed between the Vh and the number of GC between HIM0, VEG, and HIM-fed sturgeons. This is in agreement with what was reported in rainbow trout [16,54], post smolt Atlantic salmon [30], and Japanese seabass [29] fed with HIM meal. Another study conducted in Siberian sturgeon fed with HIM-based diet [18] showed that in the proximal intestine, the inclusion of 15% of full-fat HIM did not affect the villus height, but the authors reported a reduction in the thickness of mucosa and increase in muscle layer thickness-changes that have been associated with an enhancement of the digestion and absorption process.…”

“…No histopathological alterations were observed in the liver of Siberian sturgeons fed HIM based diets. This result is in agreement with those observed in Japanese seabass [29], Atlantic salmon [30,31], zebrafish (Danio rerio) [52], and rainbow trout [16] fed with HIM meal. On the contrary, Li et al [20] observed significant alterations in liver (decrease hepatopancreas fat deposition and increase in mild necrosis and apoptosis of hepatocytes) in Jian carp (Ciprinus carpio var.…”

“…Peng et al [74] measured a reduction in lipid peroxidation in fish fed with soybean meal, probably correlated with an increased storage of hepatic α-tocopherol. Likewise, Wang et al [29] found a lower concentration of MDA in Japanese seabass fed H, revealing that this diet may improve the antioxidant status of fish. On the contrary, Ji et al [75] showed that the amino acid deficiencies in diets substituted with higher silkworm pupae doses caused lipid peroxidation and oxidative damage, also altering the intestinal microvilli and hepatocytes structure in juvenile Jian carp.…”

“…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].…”

Color and sugar preferences of adult black soldier fly (Hermetia illucens) (Dipetera: Stratiomyidae) for feeding and oviposition

“…In particular, the supplemental inclusion of H. illucens larvae to poultry diets improve chicken egg productivity and weights (Park et al, 2017) as well as broiler growth (Hwangbo et al, 2009). Moreover, there has been remarkable progress on improving the feasibility of replacing unsustainable marine-based products with H. illucens larvae in the diets of some farmed fish species (Belghit et al, 2019, Wang et al, 2019Fawole et al, 2020). Further, to the biodiesel industry due to high fat content (Wong et al, 2019).…”
