European perch (Perca fluviatilis) fed dietary insect meal (Tenebrio molitor): From a stable isotope perspective

Breeding Substrate Containing Distillation Residues of Mediterranean Medicinal Aromatic Plants Modulates the Effects of Tenebrio molitor as Fishmeal Substitute on Blood Signal Transduction and WBC Activation of Gilthead Seabream (Sparus aurata)

“…In some cases, higher replacement percentages (50% FM) resulted in improved gut microbial diversity [11] and amino acid composition [2,12], while in some others, they resulted in increased operational taxonomic units without corresponding to higher diversity in gut microbiota [1]. Our results are in accordance with previous literature findings from studies that examined similar insect meal supplementation rates in terms of growth performance indices of other farmed fish species [3,13,[16][17][18][19][20][21][22] and gilthead seabream. [63].…”

“…Numerous studies have indicated the efficacy of substituting fishmeal with mealworm meals in aquaculture production, particularly at inclusion rates of up to 25% [6]. Mealworm-based feeds have received positive evaluations for various freshwater species such as Nile tilapia (Oreochromis niloticus) [7][8][9], tench (Tinca tinca) [10], rainbow trout (Oncorhynchus mykiss) [11][12][13][14][15][16][17][18][19], yellow catfish (Pelteobagrus fulvidraco) [20], black bullhead catfish (Ameiurus melas) [21], European perch (Perca fluviatilis) [22][23][24], and African catfish (Clarias gariepinus) [25] and several marine water species such as gilthead sea bream (Sparus aurata) [1,[11][12][13][26][27][28][29], European sea bass (Dicentrarchus labrax) [11,13,26], blackspot sea bream (Pagellus bogaraveo) [30], olive flounder (Paralichthys olivaceus) [31], red sea bream (Pagrus major) [32], Pacific white shrimp (Litopenaeus vannamei) [33], pearl gentian grouper (Epinephelus lanceolatus♂x Epinephelus fuscoguttatus♀) [34], and black rockfish (Sebastes schlegeli) [35]. Despite the positive evaluations, it should be noted that high levels of inclusion, particularly in fish juveniles, could potentially result in performance decrease [3,35].…”

Dietary Tenebrio molitor Larvae Meal Inclusion Exerts Tissue-Specific Effects on Cellular, Metabolic, and Antioxidant Status in European Sea Bass (Dicentrarchus labrax) and Gilthead Seabream (Sparus aurata)

“…Among the authorized species, yellow mealworm, Tenebrio molitor (Linnaeus, 1758), has gained great attention, and its suitability as ingredient in fish feeds has been studied in relation to various aspects of several reared fish species, including European sea bass Dicentrarchus labrax (Linnaeus, 1758) [ 11 , 17 ], rainbow trout Oncorhynchus mykiss (Walbaum, 1792) [ 18 , 19 ], gilthead seabream Sparus aurata (Linnaeus, 1758) [ 20 , 21 ], and European perch Perca fluviatilis (Linnaeus, 1758) [ 22 ]. Dietary inclusion of yellow mealworm has been reported to exert positive or no effect on fish growth performance, nutrient digestibility, and body composition, depending on the species [ 11 , 19 , 23 ].…”

Substitution of fish meal with Madagascar cockroach (Gromphadorhina portentosa) meal in diets for juvenile Nile tilapia (Oreochromis niloticus): effects on growth, nutrient assimilation, and nitrogen turnover rates

“…The dietary nitrogen supplied by insect meal in the combined diets promoted lower assimilation proportions in comparison to sh meal, however, differences were not signi cant. In a similar study, Tran et al (2021) reported that an insect meal (Tenebrio molitor) included in diets for perch (Perca uviatilis), contributed nutrients to the biosynthesis of muscle in proportions that were similar to the amounts of insect meal established in the diets. In the present study, results also indicate that the assimilated proportions of dietary nitrogen were similar to the dietary proportions and, as a result, the biosynthesis of muscle tissue was signi cantly supported by the available protein in insect meal.…”
