This study investigated the effects of dietary inclusion levels full-fat Hermetia illucens prepupae meal (H) on growth and gastrointestinal integrity in rainbow trout (Oncorhynchus mykiss). A 98-day was conducted using triplicate groups (initial body weight, 137 ± 10.5 g) kept 1-m3 tanks a flow-through well water system. Three treatments were prepared: one based fishmeal purified protein-rich vegetable ingredients (H0), two experimental diets including graded H (25% 50%, referred to as H25...
Intensive fish farming relies on the use of feeds based meal and oil as optimal ingredients; however, further development aquaculture sector needs new, nutritious sustainable ingredients. According to concept circular economy, insects represent good candidates aquafeed ingredients since they can be cultured through environmental-friendly, cost-effective processes, by-products/wastes, many studies have recently been published about their inclusion in feed. However, information physiological...
The attempt to replace marine-derived ingredients for aquafeed formulation with plant-derived ones has met some limitations due their negative side effects on many fish species. In this context, finding new, sustainable able promote welfare is currently under exploration. the present study, poultry by-products and Hermetia illucens meal were used vegetable protein fraction in diets totally deprived of intended gilthead seabream (Sparus aurata). After a 12-week feeding trial,...
In the present study, an organic substrate (coffee silverskin) enriched with spirulina (Arthrospira platensis; 15% w/w), as a source of lipids and bioactive molecules, was used to rear black soldier fly (Hermetia illucens) prepupae. Three grossly isonitrogenous, isoproteic, isolipidic isoenergetic experimental diets for rainbow trout (Oncorhynchus mykiss) juveniles were then produced: control diet (HM0) mostly including fish meal oil, two other test named HM3 HM20, in which 3 or 20% marine...
This review presents several alternatives to replace antibiotic therapy and make the European aquaculture industry more friendly environmentally sustainable. The first part of this highlights growing importance worldwide for its ability supply low-cost proteins lipids. second discusses different strategies these replacements, from recombinant vaccines diets with low environmental impact rich in bioactive molecules that can benefit other species. Specifically, beneficial effects compounds...
Due to minimal environmental impact, compared most conventional feed commodities, insects deserve a growing attention as candidate ingredients for aquafeeds. This study tested, the first time during zebrafish larval rearing, effects of an increasing replacement (0%–25%–50%) fish meal by black soldier fly (BSF) full-fat prepupae meal. All diets were formulated be isonitrogenous and isolipidic. A multidisciplinary approach, including biometrics, histology, gas chromatography–mass spectrometry,...
Abstract Black Soldier Fly (BSF) meal is considered as an alternative, emerging and sustainable ingredient for aquafeed production. However, results on fish physiological responses are still fragmentary often controversial, while no studies available behavior in response to these new diets. The present work represents the first comprehensive multidisciplinary study aimed investigate zebrafish behavioural BSF-based Five experimental diets characterized by increasing inclusion levels (0, 25,...
A desirable goal of the aquaculture sector is to replace most fish meal and oil with more sustainable, cost-effective, environmental friendly ingredients ensuring health welfare standards. Due minimal impact, compared conventional feed commodities, insects deserve a growing attention as candidate for aquafeeds. The present study investigated, first time, possible application 100% insect diet in zebrafish larval rearing. Through multidisciplinary approach, major biological responses new diets...
Due to the limited application of insect meal in giant freshwater prawn (Macrobrachium rosenbergii) culture, present study aimed (i) produce spirulina-enriched full-fat black soldier fly (Hermetia illucens) prepupae (HM) and (ii) test, for first time, two experimental diets characterized by 3% or 20% fish oil replacement with HM (HM3 HM20, respectively) on M. rosenbergii post-larvae during a 60-day feeding trial conducted aquaponic systems. The did not negatively affect survival rates...
Abstract Over the last years, potential use of Black Soldier Fly meal (BSF) as a new and sustainable aquafeed ingredient has been largely explored in several fish species. However, only fragmentary information is available about BSF meal-based diets sturgeon nutrition. In consideration circular economy concept more aquaculture development, present research represents first comprehensive multidisciplinary study on physiological effects diet during culture an aquaponic system. Siberian (...
The present study aimed to investigate the acute response of gilthead seabream (
A major challenge for development of sustainable aquafeeds is its dependence on fish meal and oil. Replacement with more sustainable, nutritious safe ingredients now a priority. Over the last years, among several alternatives proposed, insects have received great attention as possible candidates. In particular, black soldier fly ( Hermetia illucens ; BSF) represents concrete example how circular economy concept can be applied to culture, providing valuable biomass rich in fat protein...
Aquafeed's contamination by microplastics can pose a risk to fish health and quality since they be absorbed the gastrointestinal tract translocate different tissues. The liver acts as retaining organ with consequent triggering of oxidative stress response. present study aimed combine use natural astaxanthin natural-based microcapsules counteract these negative side effects. European seabass juveniles were fed diets containing commercially available fluorescent microplastic microbeads (1-5...
Microplastics (MPs) in fish can cross the intestinal barrier and are often bioaccumulated several tissues, causing adverse effects. While impacts of MPs on well documented, mechanisms their cellular internalization remain unclear. A rainbow-trout (Oncorhynchus mykiss) platform, comprising proximal distal epithelial cells cultured an Alvetex scaffold, was exposed to 50 mg/L (size 1–5 µm) for 2, 4, 6 h. MP uptake faster RTpi-MI compared RTdi-MI. Exposure microplastics compromised integrity by...
In the present research, bacterial diversity was studied during a 6-month feeding trial utilizing zebrafish (Danio rerio) fed Hermetia illucens reared on different substrates with an emphasis fish gut diversity. A polyphasic approach based viable counting, PCR-DGGE and metagenomic 16S rRNA gene amplicon target sequencing applied. Two H. groups were coffee by-products (C) or mixture of vegetables (S). Viable counts showed wide variability substrate. Illumina allowed major minor taxa to be...
In the present study, Hermetia illucens larvae were reared on a main rearing substrate composed of coffee roasting byproduct (coffee silverskin, Cs) enriched with microalgae (Schizochytrium limacinum or Isochrysis galbana) at various substitution levels. The microbial diversity substrates, larvae, and frass (excrement from mixed residue) studied by combination culturing growth media metataxonomic analysis (Illumina sequencing). High counts total mesophilic aerobes, bacterial spores,...
Insects represent a valuable and sustainable alternative ingredient for aquafeed formulation. However, insect-based diets have often highlighted controversial results in different fish species, especially when high inclusion levels were used. Several studies demonstrated that nutritional programming through parental feeding may allow the production of better adapted to use sub-optimal ingredients. To date, this approach has never been explored on diets. In present study, five experimental...
One of the main sources MPs contamination in fish farms is aquafeed. The present study investigated, for first time through a comparative approach, effects different-sized fluorescent included diet intended zebrafish (Danio rerio). A comparison based on developmental stage (larval vs. juvenile), exposure time, and dietary MPs' size concentration was performed. Four experimental diets were formulated, starting from control, by adding polymer (size range 1-5 µm) B 40-47 at two different...
