“…Several other benefits, including reducing environmental impacts, enhanced yield, and improved water quality, have been documented in shrimp polyculture systems by integrating fish species, bivalve species, and seaweed as subordinate species; currently, polyculture systems are being commonly and extensively researched [163,227,228]. There is also an indication that the relationship of combined species diversity within a given environment influences different ecosystem processes, including overall productivity, nutrient decomposition, and cycling [229][230][231].…”

Intensified agrochemical-based monoculture systems worldwide are under adoption to meet the challenge of human population growth and the ever-growing global demand for food. However, this path has been opposed and criticized because it involves overexploitation of land, monoculture of few species, excessive input of agrochemicals, and adverse impacts on human health and the environment. The wide diversity among polyculture systems practiced across the globe has created confusion over the priority of a single strategy towards sustainable aquaculture development and safer products. Herein, we highlight the significance of polyculture and integrated aquaculture practices in conveying the successful transition of the aquaculture industry towards sustainable development. So far, the established thought is that the precise selection of aquatic species and a focus on compatible and complementary species combinations are supposed to facilitate rapid progress in food production with more profitability and sustainability. Therefore, the advantages of species diversification are discussed from an ecological perspective to enforce aquaculture expansion. This account asserts that a diverse range of aquaculture practices can promote synergies among farmed species, enhance system resilience, enable conservation, decrease ecological footprints, and provide social benefits such as diversified income and local food security.

“…However, understanding of the ways in which positive outcomes may be consistently generated in these systems is not well resolved, likely because many of the strategies that could be adopted are currently coupled with significant trade‐offs. For example, while it may be possible to preserve or repair mangrove habitat through integrated mangrove‐shrimp farming yields from these systems can often be lower—sometimes considerably lower—in comparison to other shrimp production systems, introducing a trade‐off in viability that affects the choice a farmer make when engaging with this approach (Ahmed et al, 2018; Jonell & Henriksson, 2015; Lai et al, 2022). Also in these systems, natural food resources may not always be adequate to support increases in production, which may lead to the need to add feed to maintain production, resulting in negative effects on water quality that detract from the environmental benefit intended (Johnston et al, 2002).…”

The magnitude of negative environmental impacts generated by food production means it is now imperative we develop food systems in a way that can actively support the recovery of degraded ecosystems, while also meeting increasing demands for food and livelihoods. Aquaculture, when it utilizes the right practices and species and occurs in the right places, can strike this balance, enabling food production that supports the health of aquatic ecosystems. To ensure the efficacy of this approach, however, a clear, common understanding of the ways in which this industry can achieve this outcome is needed. This paper highlights a definition of “restorative aquaculture”, identifies global principles for the use and development of restorative practices, and identifies needs for information, data, and tools that, if addressed, would greatly expand our understanding of the ways in which aquaculture and restorative activities can have positive environmental outcomes. This guidance was developed by a working group of representatives from global aquaculture, environment, economic and academic organizations. It can assist industry and government in making decisions about sustainability as well as restoration and rehabilitation strategies that intersect with aquaculture.

“…Therefore, effort has been made recently to restore mangroves and reduce the impact of shrimp farming on the environment. Maintaining mangrove coverage at 30-50% of the total farm area has provided a high yield while ensuring other ecosystem service bene ts in the integrated mangrove-shrimp model (from 786 ± 200 for low or null coverage to 1638 ± 200 $/ha/year for 30-50% mangrove coverage) (Lai et al, 2022;Thuy and Luat, 2017). Restoration of mangrove areas is ongoing in Kien Giang, Ca Mau, and Soc Trang.…”

Historically, local communities have thrived in the coastal zones of the Mekong Delta in Vietnam, characterised by diverse habitats such as mangroves, marshes, and mudflats, harbouring significant biodiversity. However, escalating global market demands and price fluctuations have driven the adoption of more intensive aquaculture models, generating new threats to these vulnerable areas. Consequently, coastal regions face compounded hazards (high temperatures, drought, floods, high tides, sea level rise, and saline intrusion), necessitating the identification of socio-economic and ecological drivers of risks to sustainable livelihoods centred around shrimp aquaculture. This research aims to comprehend the impact of various shrimp farming models, ranging from extensive to hyper-intensive, in the context of multiple natural hazards and transformative processes like land conversion and mangrove restoration. By employing risk assessment tools and analysing qualitative and quantitative data gathered from interviews and focus groups with local communities and stakeholders, we present a comprehensive model illustrating the influence of different aquaculture models on coastal socio-ecological systems. Key findings emphasise the interplay between livelihoods, landscape conversion to shrimp farming, and factors guiding such conversions. The paper highlights how these diverse aquaculture models can augment or diminish risks to sustainable livelihoods in the Mekong Delta. It outlines the benefits, constraints, and potential hazards associated with each model and stresses the need for stakeholder collaboration to preserve vital ecosystems and their services. Additionally, the study underlines the importance of improved wastewater treatment practices among farming units to benefit neighbouring farmers and foster overall environmental well-being.
