Management of productivity, environmental effects and profitability of shellfish aquaculture the Farm Aquaculture Resource Management (FARM) model. Since 2000, the country has maintained its role as the largest global producer, processor, and trader of fish, crustaceans, and molluscs, and has emerged as a leading consumer owing to the rapid growth in income and domestic seafood demand12,13,14. Aquatic plants are listed by the Food and Agriculture Organization (FAO) under aquatic plants NEI and are underreported given the informal nature of the harvests for household and local consumption.

Aquaculture 493, 376383 (2018). According to FAO (2020), aquaculture's contribution to global fish production has continued to rise, reaching 82.1 million tons (46%) out of the estimated 179 million tons of global production. 58, 681688 (2016). Paradigm changes in freshwater aquaculture practices in China: moving towards achieving environmental integrity and sustainability. Rural Stud. In addition, improvements in processing technologies have increased fishmeal recovery from anchovies and other pelagic species from 22.5% to 24% over the past few decades53. What is aquaculture - ASC International Feeding aquaculture in an era of finite resources. Matsuyama, Y. Belton, B. Nat. The growing importance of domestic markets, particularly in Asia, means that over 89% of aquaculture output does not enter into international markets21. Phil. Ponte, S., Kelling, I., Jespersen, K.

By filtering phytoplankton and accumulating nitrogen and phosphorous, they remove nutrients from the ambient environment when harvested. ABSTRACT. Freshwater aquaculture is carried out either in fish ponds, fish pens, fish cages or, on a limited scale, in rice paddies. Marine aquaculture creates jobs, supports resilient working waterfronts and coastal communities, and provides new international trade . 51, 2635 (2012). Efforts have been made to introduce new markets for bivalves that generate offset credits for non-point source pollution, but these markets have yet to develop at scale84,94,95. Aquatic farmers can be vital observers of changing ecosystems. Aquacult. Arthur, R. I. et al. Google Scholar.

Shellfish Res. 1, 392398 (2018). 245277 (Wiley-Blackwell, 2012). For most high-value and widely traded species, there have been substantial advances in PPP identification, diagnosis, and treatment over the past 20years, derived in part from innovations in agriculture and human medicine131,132,134,135. & Watson, J. R. The growth of finfish in global open-ocean aquaculture under climate change. Peer review information Nature thanks Peter Edwards, Adam Hughes, Fabrice Pernet, Grant Stentiford and the other, anonymous, reviewer(s) for their contribution to the peer review of this work. Prudent siting and scaling are essential for maximizing the ecosystem services provided by farmed extractive species and for mitigating critical challenges to the industry associated with PPP, coastal pollution, and climate change. Mar. Asian shrimp production and the economic costs of disease. Bachis, E. Fishmeal and fish oil: a summary of global trends. As aquaculture production expands into new geographies, PPP outbreaks and the risks to human health from therapeutic management approaches will probably increase, particularly in low-income regions. Costello, C. et al. In 2017, aquaculture supplied more than 80Mt of fish and shellfish and 32Mt of seaweeds, encompassing around 425 farmed species2. The human dimension presents both the opportunity and the challenge. 10, 833851 (2018). Aquaculture at the crossroads of global warming and antimicrobial resistance. The views expressed in this article are those of the author alone and not the World Economic Forum. 1). Three main patterns of aquaculture development have characterized the sector as it matured: continued growth in the volume and value chains of freshwater aquaculture; advances in fish. Management of pathogens, parasites, and pests remains a sustainability challenge industry-wide, and the effects of climate change on aquaculture remain uncertain and difficult to validate. Disease will limit future food supply from the global crustacean fishery and aquaculture sectors. Article In response to public over- and under-regulation, several types of private governance arrangements have emerged with the intention of shaping demand for sustainable, fair, and organic aquaculture production. Change 8, 510514 (2018). Alternative oil sourcesincluding rapeseed (canola) oil, palm oil, and poultry fatare now commonly used substitutes for a portion of fish oil62. Research has examined the use of microalgal biomass in aquaculture feed as a cost-competitive replacement for fishmeal and the use of macroalgae in dairy and cattle feed to reduce methane emissions113, but these types of feed have yet to develop commercially at scale. The farmed (live-weight) production of fish and shellfish had almost tripled from 10million tonnes (Mt) in 1987 to 29Mt in 1997, and roughly 300species of animals, plants, and algae were being cultivated worldwide2. He has received funding from the Monterey Bay Aquariums Seafood Watch programme for the development of Aquaculture Governance Indicators. The restorative aquaculture approach is already starting to take hold on a global scale. World Dev. Aquacult. Marine aquaculture refers to the breeding, rearing, and harvesting of aquatic plants and animals. Prog. Hatcheries are also used for stock enhancementalso known as 'restoration aquaculture'through which fish and shellfish are raised in a hatchery and then released to supplement the populations of recreational, commercial, and ecologically-important species. Aquaculture 519, 734928 (2020). CAS Fisheries and aquaculture - OECD Mariculture Mariculture is aquaculture that involves the use of seawater. Prices deflated by the implicit GDP deflator. The literature does not support generalizations of the damages of ocean acidification to shellfish aquaculture given the species-specific responses documented, sparse data, uneven and questionable experimentation, and the complexity of pathways through which species are affected162. Fishery resources: between ecology and economy | SpringerLink Uneven regulation has led to disparities in investment and trade, with only a few export nations selling into major net seafood importing markets such as the USA and European Union. This paper presents a critical overview of the advances and challenges of implementing the ecosystem approach to aquaculture. This study provides a critical assessment of how aquaculture and fisheries compare to terrestrial livestock in terms of edible and live-weight production and growth in recent decades. 47,48) (Extended Data Fig. Fish. 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. 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. Int. 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. Integrated assessment of ecosystem-scale carrying capacity in shellfish growing areas. 2, 6270 (2019). 34, 97103 (2019). Aquaculture supplies only about 7 percentof the entire U.S. seafood supply and has a landed value of $1.5 billion. Evol. Both certification and consumer guides have now started shifting to hybrid forms of governance190, which integrate private assessment tools into spatial management units that are managed in collaboration with buyers and states198. 63, 554563 (2019). ADS Marine aquaculturerefers to the breeding, rearing, and harvesting of aquatic plants and animals. There are no comprehensive data on climate-driven production and economic losses in aquaculture at regional or global scales, and outcomes are contingent on adaptation responses129. D.H.K. Some seaweed systems receive additional fertilizers, for example, in low-nutrient coastal zones, although fertilization is regulated in Japan and South Korea115. The role of RAS in the English Aquaculture Plan The UK government was interested in the potential for RAS to help achieve the targets set out in the English Aquaculture Plan (34,608 tonnes of aquatic food production per year by 2040) whilst also achieving the sustainability objective within the Fisheries Act 2020.

Marine aquaculture creates jobs, supports resilient working waterfronts and coastal communities and provides new international trade opportunities. Aquacult. Farmed seafood products already make up half of the worlds seafood supply, but U.S. production lags behind much of the world, leading to a $16.9billion seafood deficit in the United States in 2020. Aquaculture 264, 160174 (2007). Eng. Fish. Sustain. Coast. Kibenge, F. S. B. Pressure on the aquaculture industry to embrace comprehensive sustainability measures during this 20-year period have improved the governance, technology, siting, and management in many cases. Rev. The growth of aquaculture has been fuelled by the expansion in global trade, declines in the availability of wild fish, competitive product pricing, rising incomes, and urbanizationall of which contribute to rising per capita consumption of seafood worldwide11,19.

New global initiatives to promote seaweed production and use124 will need to tackle critical social, economic, and regulatory constraints, including unethical supply chain activities125, food safety considerations, and limited consumer demand83,106,126. Freshwater aquaculture has been underrepresented in the proliferating literature on global environment and food system interactions since 2000 despite its dominant contribution to aquatic food supplies and nutrition security21,22. Manage. This paper provides a clear and comprehensive assessment of global seaweed aquaculture and shows the relevance of integrated multi-trophic aquaculture and other applications. 37, 247276 (2012). Bioremediation is the main ecological service reviewed in the literature. Opin. Fish Fish. Green, K. Fishmeal and Fish Oil Facts and Figures. Aquaculture in the Western Hemisphere has largely developed around single- or dual-species and single-production systems (for example, Atlantic salmon in cages, Nile tilapia and channel catfish (Ictalurus punctatus) in ponds). Conventional breeding and marker-assisted selection have also been used to improve fish growth and health, and lessons from terrestrial animal breeding, especially poultry, have been used to advance breeding strategies for fish68,69. A 20-year retrospective review of global aquaculture | Nature A small fraction of the aquatic plant and algae category (~32Mt) consisted of aquatic plants (1,639tonnes) in 20172. Pollut. PDF Fisheries and Aquaculture in Norway January 2021 - OECD Bivalves do not require feed inputs, making them attractive candidates for the expansion of sustainable seafooda point that was made in the previous review1 and has been argued for more than 30years82,84,86,87,88. 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. A number of assumptions were made in these calculations as SFW does not recognize a number of species certified by ASC and GAA. Elaswad, A. Research on new feed ingredients has proliferated recently59,74,78,79,80,81 and will continue to expand. Second, and related to production intensification, compound feed use in freshwater systems has steadily increased, driven by local and international companies and certification initiatives operating across a range of production systems and countries3,43. Aquaculture species differ in their defences, and although invertebrates lack the adaptive immunity of finfish, their innate immune systemwhich is certainly not simple or homogenousis not fully understood131,132,133. 54, 14641474 (2020). First, over-intensification, particularly in cage aquaculture, has created problems of nutrient pollution and pathogen-related production declines in areas with unconstrained growth, such as Lake Taal, The Philippines36. Undercurrent News (18 February 2019). For example, between 2000 and 2016, the Norwegian salmon aquaculture industry cut its shares of marine protein in feed from 33.5% to 14.5% and marine oils from 31.1% to 10.4%, and increased the shares of plant proteins from 22.2% to 40.3% and terrestrial oils from 0 to 20.2%76. Google Scholar. Bacterial and viral outbreaks are especially high in intensively farmed seaweed systems, where disease management can account for up to 50% of farm-variable costs106,121. Global production of fishmeal from capture fisheries and trimmings decreased over the same period from 6.6 to 4.8Mt (ref. Int. It includes the breeding, rearing, and harvesting of fish, mollusks, crustaceans, and plants in fresh and saltwater environments.
