“…However, ref [72] used a different system to the one presented in this study, using rearing cages in a natural environment. The stocking density used in this study was 100 shrimp per m −2 , a low density when compared to other research on the BFT system [73][74][75][76][77]. The BFT system aims for high productivity in small areas, which requires high operating costs [78]; production at very low stocking densities could make it economically unviable.…”

Shrimp farming in the Biofloc Technology System (BFT) is already considered an alternative to the traditional culture. The bioflocs maintain the water quality and can be used as a food supplement for shrimp. The Pacific white shrimp Litopenaeus vannamei forms the basis for most of the production in BFT. However, its culture is limited by the low temperatures. Thus, the BFT culture potential of native species, such as the pink shrimp Farfantepenaeus brasiliensis, should be considered. The present study aimed to compare the cultures of F. brasiliensis and L. vannamei in the grow-out phase in the BFT system. The experiment comprised two treatments: (FB), grown out of F. brasiliensis, and (LV), grown out of L. vannamei. The study lasted 70 days and was conducted at the Marine Station of Aquaculture at the Federal University of Rio Grande, Rio Grande do Sul State, Brazil. The stocking density was 100 shrimp/m² for both species. The shrimp were fed twice a day with commercial food. The physicochemical parameters of the water were monitored throughout the experimental period. The results showed that all physicochemical parameters of the water remained within the tolerated limits for both species. However, during the growth phase in the BFT, it was observed that the L. vannamei shrimp showed a better zootechnical performance than F. brasiliensis. The results indicate that L. vannamei has a higher capacity to catch bioflocs as supplementary food, demonstrating a better response of that species to the BFT system in the grow-out phase compared to F. brasiliensis.

“…It is evident that certain species of photosynthetic microorganisms respond better to particular wavelengths of light, which in turn may or may not favour the farmed animal; for example, Chlorella ellipsoidea has been shown to grow best under blue light (Baidya et al., 2021). Whiteleg shrimp ( L. vannamei ) grew better in a biofloc study under green light (out of yellow, blue, red, green, and white light treatments [control]) with a 17% improvement in FCR as well as a 2.4% increase in survival rate, compared to the white light treatment (Reis et al., 2022). The authors suggested that this may be due to potential photosensitivity of bacteria resulting from the differing light spectra; furthermore, the green light could promote the growth of microorganisms beneficial to whiteleg shrimp.…”

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.

“…Aquatic animals, such as shrimp, fish, and crab, are important food and meet people's needs for different nutrients. Light is also important to aquatic animals, such as shrimp, [34] fish, [35][36][37][38] and crab. [39] The effect of the wavelength of light on aquatic animals has been investigated.…”

The expected population growth and resulting increase in food and energy demands have become global concerns to be addressed with urgent and targeted actions. Agrivoltaics has recently emerged as the practice of co‐locating photovoltaic (PV) infrastructure and agriculture to alleviate land‐use competition between energy and agriculture production. However, PV and agriculture are highly dependent on the utilization of sunlight. Therefore, the design of a PV system is critical for maximizing electricity generation and plant biomass production. Perovskite solar cells (PSCs), as an emerging PV technology, attract intensive attention owing to low fabrication cost, high performance, and tunable transmission. Accordingly, PSCs show promising application in a net‐zero emission agrivoltaics ecosystem. In this perspective, the advantages of PSC‐integrated agrivoltaics are discussed by comparing with traditional PV technologies. Thereafter, the promising and sustainable way is proposed to employ PSCs for electricity generation, plant growth, and aquatic animal development in an agrivoltaics ecosystem. Lastly, a design principle is provided for tailoring PSCs for a sustainable agrivoltaics ecosystem to simultaneously solve the energy and food crises.
