“…The recirculation idea for an aquaculture system is by far the most prominent one to offer solutions for the CE. Carvalho Pereira et al [64] combined shrimp farming with the production of algae from wastewater and sludge from farming. Other trials have been conducted in RAS with seabass and micro algae, by Villar-Navarro et al, [65].…”

This paper offers an overview of circular economy strategies applied to the aquaculture sector. The growing challenges imposed on the sector by the strategies of the Green Deal impose new growth strategies in the name of sustainability. The scalability of these strategies is increasingly hampered by regulatory voids and by the absence of a universally accepted assessment method for measuring the impacts of current aquaculture systems. More than ever, a review of knowledge in the circular economy field is required to comprehend where the aquaculture sector is heading, and in order to make the required transition. The present review proposes a bibliometric analysis, a network analysis and a content analysis, which highlight a very new and expanding field of research. The studies were firstly analyzed from a micro (animal metabolism) to a macro perspective (policies, markets and society), emphasizing where research is still lacking. Furthermore, a second level of classification concerns the type of circularity approach proposed for the aquaculture system, which can be divided into open-loop or closed-loop strategies. Regarding the open-loop-related studies, the focus of the evaluation is devoted to the different bioeconomic values of the circularity strategies proposed for the biological flows entering and exiting the aquaculture system. The literature review offered insights into the identification of research threads that are developing around the aquaculture sector.

“…This result is in line with the ongoing scientific discussion. Most studies on CE applied to aquaculture focus on the valorization of organic waste and on the possibility of creating value proposals (Strazza et al, 2015;Campanati et al, 2022;Carvalho Pereira et al, 2022). In this regard, previous authors have presented the possibility of using organic waste from aquaculture as an input for other productions with a high bioeconomic value in the food and feed sectors (Cust odio et al, 2017;Fricke et al, 2022) or the pharmaceutical or cosmetic one (Honrado et al, 2022).…”

PurposeThis study investigates the views of Italian aquaculture production science students, in their role of future operators, on the application of circular economy strategies.Design/methodology/approachA key step in the development of professional knowledge is to solicit the opinions of the future operators in the aquaculture sector. The authors used the Q methodology to assess the perceptions of the students on four different knowledge dimensions of the CE: operations, culture and organization, products and services, and ecosystem.FindingsFour discourses emerge from the results, representing the respondents' views on the CE. The first discourse considers CE as business strategy applicable to products and services, the second a corporate mission and the fourth an operational efficiency strategy. Finally, the third discourse views CE as a multidimensional concept.Research limitations/implicationsThis study contributes to the scientific and institutional debate on how to accelerate the aquaculture's circular transition. First and foremost, it offers insights to guide policy makers in the development of appropriate knowledge and information systems. Second, it offers the opportunity to improve training programmes to enable current students to be prepared for the future challenges.Originality/valueThe results reflect a different perceived knowledge of CE among future operators, whose opinions are little explored in the literature.

“…In addition to the definition, the range of examples is also very extensive for aquaculture, and no previous studies are available that provide the state of the art of the real and current implementation of the circular economy in the sector [10]. The concept of circular aquaculture can be addressed in many ways [11], but generally, circularity in aquaculture includes the adoption of practices regarding waste management [12][13][14], the recycling of nutrients [15][16][17][18], or the incorporation of novel ingredients in feeds derived from the bio-economy [19,20].…”

Aquaculture is a strategic sector that aims to meet the increased demands for healthy food for current and future populations. However, this progression needs to be sustainable, which can potentially be achieved by the implementation of circular practices. Integrated multi-trophic aquaculture (IMTA) systems promote the incorporation of circular principles. Nevertheless, the lack of harmonized definitions and standards impedes the quantification of these circular attributes. This study aims to explore the potential principles embedded in IMTA and the existing alternatives to quantify circularity. Two basic pillars (nutrient management and resource use efficiency) were identified as the most relevant circularity attributes for IMTA systems and were quantified through aquaculture-specific indicators. Bioremediation indicators, together with the efficiency indicators in terms of feed, water, energy, and infrastructure materials used, were selected to evaluate the circularity performance of four IMTA trials in three aquaculture facilities in Ireland, Brazil, and South Africa. Salmon, white shrimp, tilapia, abalone, and sea urchins were studied and cultivated together in various combinations with several low-trophic species in these IMTA trials to evaluate the improvement in circularity compared with corresponding monoculture conditions. The results showed an increase in circularity of up to 90% in terms of water recirculation, as well as bioremediation, which was improved by 80%–90%, providing evidence for the potential role of IMTA in the circularity transition.
