“…The thematic cluster about business models and managerial issues is composed of six papers disclosing different contributions to the debate on the strategic and organisational dimensions of the blue economy and aquaculture. Rubilar and Cardozo (2021) presented evidence by comparing two aquaculture business models related to two companies, one in Norway and one in Argentina. The study highlights that success resides in the technological know-how and the development of open innovation and collaborations with a plurality of actors, including academies and businesses.…”

PurposeThe paper provides a contribution of systematisation to the literature on the blue economy and aquaculture as challenging issues for achieving sustainable growth and a circular economy. The growing scientific interest in recent years and the increased attention in political agendas make the blue economy and aquaculture as promising fields for scientific investigation. The latter has been confirmed during a particular period too as the pandemic times. To identify those areas of specialisation emerging from the intersection of such topics, the paper embraces a systematic literature review for inspiring future research.Design/methodology/approachThe study covers a period of 20 years by including 85 papers extracted from the Scopus database. Through the adoption of VOSviewer, the investigation explores the main descriptive statistics, while content analysis has been embraced to identify thematic areas.FindingsThe main results of this study are about statistics (i.e. publication trends, geographic distribution, most frequent keywords and most influential authors, etc.). Three main thematic areas have been identified in this study: SDGs and policies for sustainable development, food and energy, business models and managerial issues.Practical implicationsPractical implications arise both for firms and policymakers. About the firsts, interesting insights can be derived in terms of business model innovation, collaborative approaches and technological exploration. About policymakers, inspiration in terms of renewal of strategic guidelines, creation of enabling contextual conditions and evidences for new regulations can be noted.Originality/valueElements of original contributions can be identified in the adoption of an SLR to verify the advancement of the debate till the recent pandemic.

“…Both sea urchins (Echinoidea) and sea cucumbers (Holothuroidea) have high commercial value and are extensively exploited (Kelly, 2005; Cirino et al ., 2017; Hu et al ., 2021; Rubilar & Cardozo, 2021). Sea urchins are considered ideal models for marine (eco)toxicological tests (Goldstone et al ., 2006; Gharred et al ., 2016) as their embryos can sense adverse effects related to a wide range of environmental stressors, including metals and plastics (Pinsino et al ., 2017; Messinetti et al ., 2018; Morroni et al ., 2018; Bergami et al ., 2019; Oliviero et al ., 2019), polluted sediments and ocean acidification (Pagano et al ., 2017; Dorey et al ., 2018; Bonaventura et al ., 2021; Caetano, Pereira & Envangelista, 2021).…”

Aquatic invertebrates play a pivotal role in (eco)toxicological assessments because they offer ethical, cost‐effective and repeatable testing options. Additionally, their significance in the food chain and their ability to represent diverse aquatic ecosystems make them valuable subjects for (eco)toxicological studies. To ensure consistency and comparability across studies, international (eco)toxicology guidelines have been used to establish standardised methods and protocols for data collection, analysis and interpretation. However, the current standardised protocols primarily focus on a limited number of aquatic invertebrate species, mainly from Arthropoda, Mollusca and Annelida. These protocols are suitable for basic toxicity screening, effectively assessing the immediate and severe effects of toxic substances on organisms. For more comprehensive and ecologically relevant assessments, particularly those addressing long‐term effects and ecosystem‐wide impacts, we recommended the use of a broader diversity of species, since the present choice of taxa exacerbates the limited scope of basic ecotoxicological studies.This review provides a comprehensive overview of (eco)toxicological studies, focusing on major aquatic invertebrate taxa and how they are used to assess the impact of chemicals in diverse aquatic environments. The present work supports the use of a broad‐taxa approach in basic environmental assessments, as it better represents the natural populations inhabiting various ecosystems. Advances in omics and other biochemical and computational techniques make the broad‐taxa approach more feasible, enabling mechanistic studies on non‐model organisms. By combining these approaches with in vitro techniques together with the broad‐taxa approach, researchers can gain insights into less‐explored impacts of pollution, such as changes in population diversity, the development of tolerance and transgenerational inheritance of pollution responses, the impact on organism phenotypic plasticity, biological invasion outcomes, social behaviour changes, metabolome changes, regeneration phenomena, disease susceptibility and tissue pathologies. This review also emphasises the need for harmonised data‐reporting standards and minimum annotation checklists to ensure that research results are findable, accessible, interoperable and reusable (FAIR), maximising the use and reusability of data. The ultimate goal is to encourage integrated and holistic problem‐focused collaboration between diverse scientific disciplines, international standardisation organisations and decision‐making bodies, with a focus on transdisciplinary knowledge co‐production for the One‐Health approach.

“…Although echinoculture has been practised for several decades, it still has not achieved economic sustainability 8, [12][13][14] . In recent years, many companies worldwide have tried to meet the strong demand for sea urchins by experimenting with various farming techniques 5 . However, despite the strong research effort, economic sustainability is still to be attained on a productive scale.…”

Sea urchin aquaculture represents a promising tool to achieve sustainable aquaculture, promote sector diversification and obtain high-priced products using low-trophic species. However, although echinoculture has been practised for several decades, this sector has not yet achieved economic sustainability and large-scale development mainly due to problems linked to long-term sea urchin rearing cycles. In this paper we present a groundbreaking production method, called "Raking", for sea urchin caviar production that represents a technological advancement both in terms of production approach and in the final product. Raking, in fact, is a no-kill method for the harvesting of eggs as a final product (sea urchin caviar) from only-female batches of sea urchins, meaning that the same sea urchins are employed through several production cycles. This method, therefore, helps overcome important biological and economic constraints of echinoculture, such as high mortality in the early development stages and the slow speed of growth to reach viable market size. This new production method was compared with a traditional gonad enhancement method known as Bulking. Our results showed that multi-cycle production using the Raking method proved more profitable and sustainable than the Bulking method, and in fact allowed us to obtain a cyclic ovulation with a total regenerative capacity of the ovary of about 3/4 months, employing the same sea urchin batch in each productive cycle. In addition, the sea urchin caviar harvested in this way was appreciated by assessors in terms of its sensory qualities and was actually preferred to the traditional gonad products, when assessors were informed of the sustainability and ethical criteria of the Raking production method.
