Abstract:
... An Eulerian-Lagrangian method was used to study the breakage of aquaculture feed pellets for during pneumatic conveying. Computational fluid dynamics (CFD) coupled with a discrete element method (DEM) was used to simulate gas–solid two phase flow. Gas flow was described by the continuous phase using ANSYS Fluent software with particles described by the discrete phase using EDEM software. The parti ...
... Aquaculture is considered one of the world's fastest‐growing food production industries. It provides one of the most environmentally friendly sources of edible protein. The rapid expansion of aquaculture has occurred in response to a huge increase in world population and the corresponding demand for food, highlighting a path towards intensive sustainable products and resource efficiency. Improved ...

Abstract:
... Enclosure lake aquaculture causes lake eutrophication and emits CH₄ to the atmosphere. So far, little is known about the rate of CH₄ emission from lake aquaculture and about how ecological restoration (or aquaculture abandonment) affects the emission. In this study, the eddy covariance (EC) technique was deployed to quantify the CH₄ flux in an enclosure lake aquaculture farm and to investigate the ...

Abstract:
... Commercial diets for tilapia juveniles contain high levels of plant protein sources. Soybean meal has been utilised due to its high protein content; however, soy-based diets are limited in methionine (Met) and require its supplementation to fulfil fish requirements. dl-Methinone (dl-Met) and Ca bis-methionine hydroxyl analogue (MHA-Ca) are synthetic Met sources supplemented in aquafeeds, which may ...
... Hydrolysates of slaughtering plants by-products are among the most promising feedstuffs for aquafeed formulations, supplying diets with amino acids and small peptides which perform functions ranging from palatability enhancers to nutrient-rich ingredients to immunity modulators. This study evaluated growth performance, blood and immunological parameters, and gene expression of food intake-regulati ...

Abstract:
... The sustainability of the aquaculture sector depends mainly on the search for alternative sources to fishmeal and fish oil, one of which is microalgae. However, there are few feasibility studies of the microalgae process chain. This work aimed to address this gap through a TEA of microalgae (Phaeodactylum tricornutum) production. The TEA combines process modelling, engineering design and economic ...

Abstract:
... Aquaculture is critical for ensuring global food and nutrition security, and fed-aquaculture, which depends on formulated nutritionally balanced manufactured feeds, must be sustainable. Single-cell ingredients (SCI) are predicted to play a significant role in future aquafeeds and have the potential to underpin sustainable fed-aquaculture for many species. The value of an aquafeed ingredient includ ...

Abstract:
... In the effort to increase the commercial value of urchin gonads produced via roe enhancement aquaculture, a variety of formulated feeds have been tested to increase gonad production and improve colour and taste. The addition of dried algal supplements to formulated feeds can further enhance gonad quality, but the level of improvement is highly variable and algae or urchin species dependent. Here w ...

This study assesses the effect of inclusion of n–3 C₁₈ rich oils on nutrient profile and quality of flesh in gilthead seabream (≈ 61.5 g) after feeding isoproteic and isolipidic diets in which camelina seed (CSO) or chia oil (CO) totally or partially replaces fish oil (FO) for 110 days. Fillet fatty acid (FA) profile reflects dietary FA profile, characterized by increased C₁₈ polyunsaturated FA (P ...

Abstract:
... Diatoms (Bacillariophyceae) are important to primary productivity of aquatic ecosystems. This algal group is also a valuable source of high value compounds that are utilised as aquaculture feed. The productivity of diatoms is strongly driven by light and CO2 availability, and macro- and micronutrient concentrations. The light dependency of biomass productivity and metabolite composition is well re ...

The present study aimed to contrast the fatty acid (FA) profile of ascidians (Ascidiacea) and seaweeds (sea lettuce, Ulva spp. and bladderwrack, Fucus sp.) occurring in a coastal lagoon with versus without the influence of organic-rich effluents from fish farming activities. Our results revealed that ascidians and seaweeds from these contrasting environments displayed significant differences in th ...

Abstract:
... Astaxanthin is a high-value carotenoid currently being produced by chemical synthesis and by extraction from the biomass of the microalga Haematococcus pluvialis. Other microalgae, such as Chlorella zofingiensis, have the potential for being used as sources of astaxanthin. The differences between the synthetic and the microalgae derived astaxanthin are notorious: not only their production and pric ...
