The aquaculture industry must continue to reduce its reliance on finite marine ingredients and promote biocircularity enhance sustainability. This study evaluated the effects of no‐fishmeal (FM) diets fish protein hydrolysates (FPHs) growth performance, antioxidant status, immune responses gilthead seabream ( Sparus aurata ). Following established conditions, two FPHs were prepared from enzymatic hydrolysis discards whole‐body blue whiting Micromesistius poutassou ) gurnard heads Trigla...
The quality of fish flesh depends on the skeletal muscle's energetic state and delaying energy depletion through diets supplementation could contribute to preservation traits modulation allergens. Food allergies represent a serious public health problem worldwide with being one top eight more allergenic foods. Parvalbumins, have been identified as main allergen. In this study, we attempted produce low farmed improved muscle in controlled artificial conditions by supplementing commercial diet...
To support the expected increase in aquaculture production during next years, a wider range of alternative ingredients to fishmeal is needed, towards contributing an sustainability. This study aimed test diets formulated with non-conventional feed on gilthead seabream (Sparus aurata) growth performance, utilization, apparent digestibility nutrients and nutrient outputs environment. Four isonitrogenous isoenergetic were formulated: control diet (CTRL) similar commercial three experimental...
Aquaculture is one of the most thriving animal production sectors, and Nile tilapia (Oreochromis niloticus) farming represents 8% total finfish culture. However, industry sustainability depends on development cost-effective environmental friendly feeds. This study aimed to reduce dietary protein levels in diets for juvenile minimize diet impact while maximizing biological efficiency. A growth trial was performed using five isoenergetic plant protein-based with decreasing crude protein: 360,...
The quality and shelf life of fish meat products depend on the skeletal muscle's energetic state at slaughter, as decomposition processes can be exacerbated by energy depletion. In this study, we tested dietary glycerol a way replenishing muscle glycogen reserves farmed gilthead seabream. Two diets were in duplicate (n = 42/tank). Results show 5% inclusion crude seabream induces increased glycogen, ATP levels firmness, with no deleterious effects terms growth, proximate composition, fatty...
Taurine is a sulphur-containing amino acid with important physiological roles and key compound for the synthesis of bile salts, which are essential emulsion absorption dietary lipids. This study aimed to evaluate effects taurine supplementation low-fishmeal diets on metabolism taurine, acids, lipids Senegalese sole. A fishmeal (FM) plant-protein-based (PP0) diet were formulated, latter was supplemented at 0.5 1.5% (diets PP0.5 PP1.5). Diets assigned triplicate tanks containing 35 fish...
The larval stage is highly prone to stress due the ontogenetic and metabolic alterations occurring in fish. Curcumin inclusion diets has been shown improve growth by modulating oxidative status, immune response, and/or feed digestibility several fish species. aim of present work was assess if dietary curcumin could promote marine larvae digestive maturation robustness. Gilthead seabream were fed a diet supplemented with at dose 0 (CTRL), 1.5 (LOW), or 3.0 g/Kg for 27 days. From 4 24 days...
Abstract Methionine is a limiting amino acid (AA) in fish diets, particularly those containing high levels of plant protein (PP), and key the immune system. Accordingly, outcome on mechanisms methionine-deficient methionine-supplemented diets within context 0 % fishmeal formulation, after short prolonged feeding period, was studied European seabass ( Dicentrarchus labrax ). For this, juveniles were fed (i) fishmeal-free diet, meeting AA requirements, but deficient methionine (MET0·65); (ii)...
Somatic growth is a balance between protein synthesis and degradation, it largely influenced by nutritional clues. Antioxidants levels play key role in turnover reducing the oxidative damage skeletal muscle, hence promoting performance long-term. In present study, Senegalese sole postlarvae (45 days after hatching, DAH) were fed with three experimental diets, control (CTRL) two supplemented natural antioxidants: curcumin (CC) grape seed (GS). Trial spanned for 25 performance, muscle...
An imbalance in the production and detoxification of reactive oxygen species other oxidants can disrupt all types cellular compounds, lead to a state oxidative stress. Preventing this is essential improve growth health animal production. Therefore, aim work was assess if dietary supplementation curcumin could antioxidant status intestine structure functionality gilthead seabream postlarvae, with global objective improving fish performance robustness. Two experimental diets supplemented...
This study investigated the effect of dietary glycerol on metabolism juvenile tilapia (Oreochromis mossambicus) and to determine its metabolic fate. The experimental diets contained 0% (Group CON), 5% G5) 15% G15) were fed for 40 d apparent satiation, three times a day. For trials, six fish from each treatment randomly chosen tube-fed with five pellets labelled 14C-glycerol [14C(U)] in order evaluate absorption, catabolism, retention partition muscle liver. Group G5 presented highest lowest...
Abstract Commercial diets for tilapia juveniles contain high levels of plant protein sources. Soybean meal has been utilised due to its content; however, soy-based are limited in methionine (Met) and require supplementation fulfil fish requirements. dl -Methinone ( -Met) Ca bis-methionine hydroxyl analogue (MHA-Ca) synthetic Met sources supplemented aquafeeds, which may differ biological efficiency structural differences. The present study evaluated the effect both on metabolism growth Nile...
New and more efficient methods to sustainably intensify Aquaculture production are essential attain the seafood demand for direct human consumption in near future. Nutrition has been identified as one strategy of early exposure that might affect animal development later phenotype. This may have positive consequences modulation fish digestive physiology, which will correlate with higher performance outputs. Thus, improving efficiency lead productivity lower biogenic emission from aquaculture...
Plant extracts are known for their high content and diversity of polyphenols, which can improve fish oxidative status. A growth trial with Senegalese sole postlarvae (45 days after hatching) fed one four experimental diets—control (CTRL), supplemented curcumin (CC), green tea (GT), grape seed (GS) extracts—was performed to assess if supplementation could performance At the end trial, were submitted a thermal stress robustness. Sole was improved by CC GS diets when compared those CTRL. CTRL...

Abstract The present study aimed to assess the efficacy of supplemental plant essential oils (PEOs) on growth performance and digestive processes juvenile gilthead seabream. Three experimental diets were tested: (1) a control (CTRL) diet formulated with low marine‐derived protein level (19%); (2) CTRL supplemented blend anise, citrus, oregano at 1.2 g/kg (diet Phyto C); (3) similar 0.2 g/kg, but in encapsulated form E). Triplicate groups 20 fish (mean initial body weight = 27.9 ± 2.1 g) fed...
A 70 days feeding trial was carried out on juvenile gilthead seabream (Sparus aurata) (mean initial body weight: 362 ± 59 g) to evaluate whether the simultaneous replacement of fishmeal and fish oil by vegetable ingredients affected muscle's proteolytic potential. Fish were fed either a fishmeal/fish diet, fishmeal/vegetable plant protein/fish or protein/vegetable diet. The use dietary proteins resulted in lower sulphated glycosaminoglycans' content glycogen phosphorylase activity muscle,...
