“…Sensitivity analysis and statistics are recommended to strengthen the LCA results and conclusions (Henriksson et al 2012). Santos et al (2015) compared the production of two freshwater prawn species, and the results indicated that the exotic species M. rosenbergii had a lower impact than did the native M. amazonicum in all seven impact categories evaluated. The emergy analysis is a methodology that evaluates the amount of energy of all inputs and processes to elaborate a product (Odum 1996).…”

“…In addition to the impacts related to the increase in nutrient levels, the effluent could contain medicines that are used to treat fish disease during the production cycle (Santos et al . ) and cause sedimentation of the water bodies (Páez‐Osuna ; Bouwman et al . ).…”

“…Therefore, there is an increase in the water treatment costs to reach sanitary levels for human consumption, and it is necessary to invest in technology to remove organic matter, nutrients, toxins and pathogens (Tundisi 2003;Oliveira et al 2014). In addition to the impacts related to the increase in nutrient levels, the effluent could contain medicines that are used to treat fish disease during the production cycle (Santos et al 2015) and cause sedimentation of the water bodies (P aez-Osuna 2001; Bouwman et al 2013). The release of exotic species is another impact of the effluent discharge.…”

Aquaculture is responsible for almost 50% of the global production of aquatic organisms. However, the activity generates residues that cause environmental impacts. Several strategies can be adopted from the planning stage to the residue treatment to reduce these negative impacts. Alternative rearing systems, such as integrated multi‐trophic aquaculture (IMTA), integrated aquaculture‐agriculture systems, recirculation systems (RAS) and biofloc (BFT), can be implemented in place of the traditional monocultures. At the residue treatment stage, the solids particles can be removed by the settlement of suspended solids in tanks or mechanical filters. The reduction in dissolved nutrients is used in biological filters, constructed wetlands or the irrigation of agricultural crops. Finally, we describe the methodologies that are used to estimate the aquaculture environmental impacts. These methodologies allow the stages and processes that have a higher environmental impact in the production chain to be identified. Among them, we can highlight the life‐cycle assessment (LCA), emergy analysis and ecological footprint. The strategies described in this study can contribute to increasing aquaculture sustainability; however, studies should be developed that focus on more than just productivity and profitability, as it is necessary to include social and environmental issues.

“…It can for example be done by integrating a substrate on which natural food can grow or by adding filter‐feeding fish (Santos et al . ). Two main kinds of IMTA exist: aquaponics and IAA, on which two and five LCA studies have been conducted until now, respectively (see Table ).…”

The aquaculture sector is anticipated to be a keystone in food production systems in the coming decades. However, it is associated with potentially important environmental damages caused by its contribution to eutrophication or climate change, for example. To comprehensively quantify those impacts, life cycle assessment (LCA) studies have been conducted on several seafood farming systems for the past 15 years. But, what major findings and common trends can we draw from this pool of studies? What can we learn to provide recommendations to decision and policymakers in the aquaculture sector? To address these questions, we performed a critical review of 65 LCA studies of aquaculture systems from the open literature. We conducted quantitative analyses to explore which impacts can be identified as dominating and to compare different types of aquaculture systems. Our results evidenced that the feed production is a key driver for climate change, acidification, cumulative energy use and net primary production use, while the farming process is a key driver for eutrophication. We also found that different aquaculture systems and technology components may exert considerably different environmental impacts. Based on identified patterns and comparisons, we therefore provided specific recommendations to aquaculture stakeholders for future policy and system development. Overall, the analysis of existing studies demonstrates that important insights can be gained by applying LCA to aquaculture systems, and, to move towards an environmentally sustainable aquaculture sector, we recommend its systematic use in the design of new aquaculture systems or policies, and/or in the evaluation and optimization of existing ones.
