The industry is investigating recirculating and offshore technologies to reduce its exposure to and impact on aquatic environments; however, these systems will require innovative financial and environmental management to have any chance of widespread success. & Shumway, S. in New Technologies in Aquaculture: Improving Production Efficiency, Quality and Environmental Management(eds Burnell, G. & Allan, G.) 580609 (Elsevier, 2009).

Sci. Sci. Science 347, 133135 (2015). Metian, M., Troell, M., Christensen, V., Steenbeek, J.

Almost all freshwater and marine aquaculture systems interact with the ambient aquatic environment and both benefit from and provide environmental services to the ambient environment as a result. Increased attention has been directed to ecosystem-based management, system design, and new forms of private and public sector governance to manage biological and climate risks, and encourage sustainable aquaculture production86,169,170. Trends in global aquaculture and aquafeed production: 20002017. Hurd, C. L., Harrison, P. J., Bischof, K. & Lobban, C. S. Seaweed Ecology and Physiology 2nd edn (Cambridge Univ.

PubMed & Belton, B. is a member of the Technical Advisory Group for the Aquaculture Stewardship Council and a member of the Aquaculture Technical Advisory Committee of Monterey Bay Aquariums Seafood Watch Program. Aquaculture notably affects people and societies far beyond obvious contributions to food security or any positive or negative environmental impacts. A continuation of this trend could push fishmeal and fish oil prices higher, creating further incentives for innovations in aquaculture feed. Sci. Front. The estimated use of trimmings is three times the use of wild fish in fishmeal for tilapia and catfish. It consists predominantly of household-managed ponds and small- to medium-scale commercial enterprises that produce a variety of carps and other fish in polyculture systems for local and regional consumption24. Fang, J., Zhang, J., Xiao, T., Huang, D. & Liu, S. Integrated multi-trophic aquaculture (IMTA) in Sanggou Bay, China. Algae 29, 249265 (2014). There are no comprehensive data on the nature and extent of therapeutic use in most aquaculture sectors, and both good and bad practices are found worldwide141,142,143,144. Despite the positive contribution of trimmings to global fishmeal production, aquaculture production in Asianotably China, Thailand, and Vietnamstill relies on low-value feed-grade fish from non-targeted fisheries (including quasi-targeted bycatch) as an input for feeds57.

Antibiotic resistance increases with local temperature. In the absence of reliable data, the incidence and management of PPP throughout the global aquaculture industry is and will remain highly unpredictable. The process of globalization itself has been dynamic, with incomes and markets in the global South expanding more rapidly than the global North in recent decades20. World aquaculture production of animal species grew by 2.7 percent in 2020 compared with 2019, an all-time low rate of annual growth in over 40 years. M.T. Policy 106, 103547 (2019). However, the net increase of 2.3 million tonnes in the same period was comparable to some years in the last decade. Inland aquacultureespecially in Asiahas contributed the most to global production volumes and food security. This paper provides a comprehensive overview of public and private governance initiatives for aquaculture within the global sustainable seafood movement. By filtering phytoplankton and accumulating nitrogen and phosphorous, they remove nutrients from the ambient environment when harvested. Breeding strategies for salmon and trout and improvements in feed ingredient quality and formulations have permitted much higher inclusion of plant protein concentrates in feed54. This paper reviews the technologies used to improve the nutritional quality of plant protein concentrates and other alternative feed ingredients to support efficient fish growth when included in fish feeds. J. Shellfish Res. Third, careful siting of aquaculture systems underpins the commercial and environmental success of the industry. Value in the seaweed industry could be enhanced through the adoption of a biorefinery approach to processing, in which the most valuable products from the algal biomass are extracted sequentially, leaving the remaining material for commodity uses and minimizing waste, energy inputs and environmental harm123. A review and critical analysis of the actual and purported benefits of seaweed for human nutrition. Aquaculture 264, 160174 (2007). In 2015, 92 million tons of wild species were harvested worldwide - the same amount as in 1995. Froehlich, H. E., Gentry, R. R. & Halpern, B. S. Global change in marine aquaculture production potential under climate change. Interact. Bioremediation is the main ecological service reviewed in the literature. Aquaculture 493, 376383 (2018). Fishmeal and fish oil remain important ingredients of fish feed, suppling essential nutrients to support larval and fry performance and survival, but are now used at lower percentages in grow-out, broodstock, and finishing feeds. These species include salmon, catfish, oysters, scallops, sturgeon, crawfish and sea cucumber. Finally, future policies and programmes to promote aquaculture will require a food systems approach that examines nutrition, equity, justice, and environmental outcomes and trade-offs across land and sea. Ser. She participates on the editorial board of Aquaculture Environment Interactions. Globally, 18.7 million people currently work as fish farmers and, as with fisheries, this figure increases by three- to fourfold if secondary and postharvest employment is included (FAO 2016 ).

New tools, including high-throughput technologies (metabolomics and proteomics), RNA sequencing, polymerase chain reaction (PCR) and whole-genome sequencing, have been used since 2000 to detect and mitigate these problems67. J. Invertebr. Tangprasittipap, A. et al. Despite its success in substituting fishmeal and fish oil with plant-based alternatives, including non-genetically engineered soy, the industry has been under pressure to identify new feed sources to eliminate the environmental damages associated with forest conversion to crop production in Brazil77, and parts of the industry have already banned the use of Brazilian soy in aquafeed.

A few major exceptions include Chinas success in cultivating alginate-bearing seaweeds (Saccharina japonica, also known as Laminaria japonica) and the expansion of agar-bearing seaweed aquaculture (Gracilaria) at scale. Aquaculture is the breeding, rearing, and harvesting of animals and plants in all types of water environments, including ponds, rivers, lakes, and the ocean. These trends reveal increasingly tight connections between land and sea. Edwards, P. Aquaculture environment interactions: past, present and likely future trends.
