Abstract Shrimps are one of the most important cultures in aquaculture with an estimated production around 4.5 million MT , that is constantly growing. This fact entails necessity to increase aquafeed meet demand. As other species, fishmeal ( FM ) main protein source used shrimp feeding. In this context, current review summarises several innovative sources for nutrition, focusing primarily on those less commercialised including fishery by‐products, terrestrial animal single‐cell proteins,...
In keeping with the premises of Blue Circular Economy in European Union, present study explored possibility using invasive brown alga Rugulopteryx okamurae aquafeeds for sea bass (Dicentrarchus labrax). Assuming raw algae biomass could negatively impact animal performance, four experimental formulations were prepared, by including macroalgae material at 5%, crude (CR), enzymatically hydrolysed and fermented (EF), (E), or (F) R. biomass, which we tested against a control feed (CT). To...
The objectives of this study were to evaluate the in vitro protein hydrolysis five algae (Arthrospira sp., Chlorella Tisochrysis Microchloropsis sp. and Ulva rigida) by digestive proteases Scophthalmus maximus, assess effect feeding turbot juveniles on diets supplemented with these a 60-day trial. results revealed that algal was hydrolysed proteases. Besides, quantification total amino acids released during evidenced noticeable acid bioavailability, mainly case Arthrospira up 42.7% after 120...
The aim of this study was to evaluate the inclusion two macroalgae as dietary ingredients on growth, body composition, intermediate metabolism, intestinal enzymes and gut histology Sparus aurata juveniles. Six isocaloric isonitrogenous diets incorporating 5%, 15% or 25% Gracilaria cornea Ulva rigida meal were tested against a control diet. Duplicate groups fifteen fish (14 g) fed experimental for 70 days. Growth performance showed an inverse linear relationship with level Gracilaria. Feed...
This study evaluates the effects of macroalgae Ulva ohnoi on growth and intestinal functionality integrity Solea senegalensis juveniles in a 90-day feeding trial. diet (U-5) included 5% dry U. biomass, whereas an algae-free was used as control. After being fed for 45 90 days, fish body weight recorded evaluation, biological samples were taken. The inclusion (5%) significantly affected performance sole juveniles, given that after days showed lower weight, specific gain rates than with control...
Five experimental diets (CTRL, 50FMFO, 50FMFO-50MIC, 0FMFO-50MIC, 0FMFO-100MIC) were formulated to replace wild-caught fishmeal (FM), fish oil (FO) and soy protein using fisheries, aquaculture byproducts (BP) microalgae (MIC).Fifty European sea bass juveniles distributed in 15 tanks (initial body weight 46.66 ± 0.04 g) reared a recirculating system for 88 days.Temperature, salinity, oxygen photoperiod kept constant throughout the experiment (22 0.5 • C, 25 g L -1 8.0 1.0 mg , 12:12...
In this study, an extract of white grape marc (GME), a by-product obtained during the winemaking process, was applied to surface gilthead seabream (Sparus aurata) fillets, which were then stored under refrigeration (4 °C) for period 14 days. The effects GME compared with those ascorbic acid (one few additives authorized fresh fish in EU) and distilled water (as control batch). Samples taken at 1, 2, 4, 7, 9, 11, days postmortem (dpm) cold storage, several objective quality parameters...
Abstract The aim of this work was to evaluate two functional feeds for the gilthead seabream, Sparus aurata , containing low inclusion microalgae-based products (LB-GREENboost, LB Gb ; and LB-GUThealth, Gh ). Fish (12–13 g) were fed 13 weeks a control diet or one four diets supplemented with both at 0.5% 1%. did not affect specific growth rate survival, but increased feed efficiency by decreasing intake enlarging intestines. hepatosomatic index reduced cortisol levels in plasma, while...
The demand for aquafeed is expected to increase in the coming years and new ingredients will be needed compensate low fish meal oil availability. Microalgae represent a promising matrix future formulation, however, high production cost hinders its application. use of microalgae from biorefinery would reduce disposal costs production. present study aimed (i) verify growth on digestate pig farming (ii) evaluate their potential valorization as dietary ingredient according Circular Bioeconomy...
Numerous studies have reported the disadvantages of using plant protein in aquafeeds owing to presence antinutritional factors. Particularly, phytate can be overcome by dietary supplementation with exogenous phytase. On other hand, use microalgae has been proven a valuable strategy for enhancing digestive functionality fish fed diets high content. It was hypothesized that simultaneous inclusion phytase useful improve growth performance and content protein. In this study, effects feeds...
In recent years, a clear emphasis has been placed on replacing fishmeal and fish oil in aquafeeds with other alternative ingredients, including algae, particularly low trophic omnivorous species. This work aimed at evaluating the effects of moderate dietary supplementation green microalga Chlorella fusca growth, metabolism, digestive functionality juvenile thick-lipped grey mullet ( Chelon labrosus ). Fish were fed control diet (CT) or containing 15% C. (C-15) biomass during 90 days. C-15...
This study aimed to evaluate the combined effect of dietary Chlorella fusca and ethanol-inactivated Vibrio proteolyticus DCF12.2 (C + V diet) in Chelon labrosus juveniles, highlighting their nutritional, physiological, morphological effects. The results showed that inclusion C. V. significantly enhanced growth performance feed utilization compared control group. C diet increased fish lipid quality index (FLQ), n-3 polyunsaturated fatty acids, n-3/n-6 ratio, which might be beneficial terms...
The increasing expansion of the invasive Asian alga Rugulopteryx okamurae along Andalusian coasts is a major challenge to marine biodiversity, and urgent coordinated measures are required for its removal or elimination. Among different actions, biotechnological valorisation could be strategy management alien biomass within frame Blue Economy. This work evaluates potential R. biomass, either raw processed by treatments based on enzymatic hydrolysis fermentation processes, used as dietary...
Microalgae are a source of diverse high-value compounds, such as carotenoids and fatty acids, which have potential application in aquafeeds. Some microalgae species present complex cell wall structures, make them poorly digestible, thus limiting their use feed ingredient. Consequently, applying extracted compounds to aquafeeds instead using the whole algal biomass is advantageous this expected increase bioavailability these nutrients. The aim study was evaluate effect dietary inclusion (2%)...
