“…Aquaculture has been one of the fastest growing food production systems in the world over the past 30 years (Cooney et al, 2021;Hua et al, 2019). The booming aquaculture industry led to the increasing demand for protein sources including fish meal (FM) and soybean meal (SBM), and as a result, the prices of FM and SBM increased rapidly (Hao et al, 2020;Jiang et al, 2012;Li et al, 2021).…”

With the development of processing technology, cottonseed protein concentrate (CPC) has been widely used as a new protein source to replace fish meal in aquaculture. But whether CPC can replace soybean meal still needs investigation. A ten-week experiment was designed to evaluate the impact of replacing soybean meal (SBM)[45%], CPC75 [75%] and CPC100 [100%]) on Nile tilapia (Oreochromis niloticus). The results showed that 45% or higher CPC substitution significantly retarded the growth performance. Increased intestinal permeability was found in the CPC75 and CPC100 treatments. To investigate whether the residual gossypol is account for the intestinal dysfunction, an 8-week feeding trial including a control diet (CON), a control diet supplemented with 150 mg/kg gossypol (ML) and 300 mg/kg gossypol (MH) treatments, was conducted. The results showed that the transepithelial resistance (TER) was significantly decreased in MH treatment. In conclusion, the replacement of 30% SBM protein by CPC can be used for Nile tilapia's dietary needs, while 45% or higher CPC substitution of SBM influenced the intestinal health and growth condition of Nile tilapia.

“…The current tranche of studies, in general, have focused on high‐value species of interest to western markets, such as Atlantic salmon, rainbow trout, penaeid shrimps, and bivalves (Alonso et al., 2021; Cao et al., 2011; Malcorps et al., 2019; Philis et al., 2019). In addition, a variety of aquaculture systems have also been assessed, including RAS, IMTA, aquaponic, cage culture, and polyculture (Boxman et al., 2016; Chang et al., 2019; Cooney et al., 2021; Medeiros et al., 2017; Newton & Little, 2018). Despite this wide body of research into aquaculture LCA, BFT and the role that it can play in circular aquaculture is an area that is understudied.…”

Increased food demand, reflecting a rising global human population, attaining 8 billion in 2022, has furthered the intensification of farmed aquatic animal production. Intensification practices can be resource demanding for micro and macronutrients, dedicated feeds, fossil fuels, chemotherapeutics, and water. Water replaces evaporative losses and may be used to dilute nutrient‐rich wastewater. As an alternative to wastewater discharge, biofloc technology (BFT) uses microbes to manage nutrient levels in production systems. A microbial community grown at high densities can assimilate waste metabolites for growth. This is promoted by increasing the carbon–nitrogen (C:N) ratio using a combination of aquafeed fed to the fish and an additional carbohydrate source, for example, starch, molasses, or bran. The microbial biomass offers a continuous and additional food source to the farmed animal, thus reducing the need for finished aquafeeds and lowering the feed conversion ratio. Although the approach relies on multiple interacting species, BFT can be deployed in relatively low technology settings. This review considers the basis of BFT and identifies areas for innovation and expansion. For example, control of light quantity and quality can influence the biofloc and hence the growth of cultured species. Research on biofloc aquaculture is dominated by studies using tilapia and shrimp, but the technology could be applied to other species, particularly species that are tolerant of biofloc conditions and not highly carnivorous. Biofloc may be a useful biosecurity tool for all or part of the life cycle, and meals made from dried biofloc may enhance the production of cultured species. The key benefits of BFT can potentially be seen in reduced water consumption, lower feed requirements, and improved fish health. This review differs from current review papers in proposing the use of a life cycle assessment in conjunction with BFT, which may be a useful tool for describing and communicating the relative benefits of biofloc systems and their wider environmental impact. This study will serve as a useful knowledge base of BFT information for students, researchers, and stakeholders alike, offering a central source of the main aspects around the culturing of biofloc, key parameters, common species used, areas of potential improvement, and a discussion on where the future of BFT may lie.

“…Evaluting the ecotoxicological safety of NBMS will also be importnat moving forward (Garvey et al, 2015). Examples of recent applications include wastewater treated using naturally occurring algae, bacterial and duckweed using IMTA process (O'Neill et al, 2020), use of earthworms based technology for composing and wastewater treatment applications (Cooney et al, 2021;Hylton et al, 2022;Arora and Saraswat, 2021), zooplankton for tertiary wastewater treatment to enable wastewater reuse (Pous et al, 2021). The INNOQUA (H2020) project presented reviewed and demonstrated various pathways for nature based treatment of wastewater and options for enabling wastewater reuse (Bumbac et al, 2021).…”
