3 Global landings of forage fish used for fishmeal and fish oil production. Natl Acad. Intensive and poorly managed finfish and crustacean systems can contribute to the emergence of harmful algal blooms, and shellfish, sea urchins, and sea cucumbers are common vectors for toxic microalgae98. The role of China notwithstanding, the aquaculture sector has become increasingly global, with growth rates in South America and Africa exceeding Asia during the past two decades (albeit from a much smaller production base), and with relatively rapid expansion in South and Southeast Asia compared to East Asia3,15,16. Aquacult. For example, genetically selected trout, which show improved weight gain of 1015% per generation on fully plant-protein feeds70, are able to digest amino acids from plant proteins in a similar temporal pattern as fishmeal and do not develop distal enteritis in the intestine when fed high-soy diets71.These tools have thus far been applied to only a few high-valued aquaculture species. Aquacult. The organisms bred here range from mollusks to seafood options like prawns, shellfish, and even seaweed. Aquaculture: Types, Benefits and Importance (Fish Farming) Google Scholar.

H., Levin, S. A. Adams, A. The increasing use of trimmings in fishmeal production, particularly for lower-valued freshwater species, has also had a critical role in lowering the use of wild fish in feed since 2000 (Table 1). Rev. Progress, challenges and opportunities in fish vaccine development. USA 115, 29582963 (2018). The competitiveness of recirculating aquaculture systems for full grow-out relative to other production systems remains uncertain, however, and there have been several failures in North America and Europe and few large-scale, commercial successes over multiple years179.

Bold Commitments From Major Seafood Buyers Among the pros of aquaculture, major seafood buyers, including institutional food service, restaurant chains, and retailers, have made significant commitments to buying and selling sustainably farmed seafood to remain competitive and meet their environmental and social impact goals. 233, 106531 (2020). Froehlich, H. E., Runge, C. A., Gentry, R. R., Gaines, S. D. & Halpern, B. S. Comparative terrestrial feed and land use of an aquaculture-dominant world. Extended Data Fig. In addition, supplementation of feed with nutraceuticals, plant extracts, prebiotics, and probiotics is used to boost fish growth and immunity and serves as a promising alternative to antibioticsmainly in high-value production systems, but also increasingly in lower-value freshwater systems in Southeast Asia142. Bestari, N., Edwards, P., Katon, B., Morales, A. Ytrestyl, T., Aas, T. S. & sgrd, T. Utilisation of feed resources in production of Atlantic salmon (Salmo salar) in Norway. On an edible-weight basis, however, molluscs and algae comprised only 6% and 7.6%, respectively, of total aquaculture output9. 13, e1006160 (2017). Meanwhile, fishmeal inclusion rates dropped for these species to 12%, and there is almost no fish oil used in most types of freshwater aquafeed. 6, 3950 (2019). What does aquaculture look like around the world? As aquaculture has grown to complement our wild fisheries, current and former fishermen are using aquaculture to supplement and support fishing livelihoods. Aquaculture 490, 6474 (2018). 091704, 110127 https://www.adb.org/publications/evaluation-small-scale-freshwater-rural-aquaculture-development-poverty-reduction (Asian Development Bank, 2005). Global production of fishmeal from capture fisheries and trimmings decreased over the same period from 6.6 to 4.8Mt (ref. Aquaculture has thus become more integrated into the global food system, with rapid growth in production and major transformations in feed ingredients, production technologies, farm management, and value chains. The sector has generally embraced a business and societal expectation of environmentally and socially sound practices. Zhang, W. et al. Harkell, L.

M.T. 5 ways to net a sustainable future for aquaculture Moreover, the introduction of large densities of filter-feeding bivalves to a habitat, whether in suspended or bottom culture, has the potential to impart negative changes in the water quality and benthic ecosystems (for example, depletion of phytoplankton and seston, and localized increases in sedimentation rates through bio-deposition) and can present serious disease risks96,97.

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. What can marine aquaculture do for the economy? Costello, C. et al. What is a hatchery and why is it important? Major gains have also occurred in aquaculture feed efficiency and fish nutrition, lowering the fish-infish-out ratio for all fed species, although the dependence on marine ingredients persists and reliance on terrestrial ingredients has increased.

A small fraction of the aquatic plant and algae category (~32Mt) consisted of aquatic plants (1,639tonnes) in 20172. Even in sectors in which major investments and progress have been made in the detection, avoidance, and treatment of PPP, new threats frequently emerge. CAS The sustainability of aquaculture has been debated intensely since 2000, when a review on the net contribution of aquaculture to world fish supplies was published in Nature. Freshwater aquaculture is carried out either in fish ponds, fish pens, fish cages or, on a limited scale, in rice paddies. This paper provides a perspective on the shift from wild fish to terrestrial crop-based ingredients in aquafeeds. 28, 4356 (2020). He has no affiliation with any for-profit company; all of his research is supported by the Chilean National Science Agency (ANID) and therefore has no conflict of interest with any aquaculture activity. Anim. 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.

Recirculating aquaculture systems have lower direct land and water requirements than conventional aquaculture and enable higher stocking densities174 but are constrained by large energy requirements, high production costs, waste disposal challenges, and risk of catastrophic disease failures78,175,176. It can either be done next to an ocean, with a sectioned-off part of the ocean, or in ponds separate from the ocean but containing seawater all the same.

The role of bivalves as a carbon sink or source remains unclear, however, and research aimed at measuring carbon sequestration and system performance from these systems is ongoing84,90,91. Feed ingredients from grains and oilseeds are the basis of livestock feeding, but carnivorous fish have difficulty digesting starch, non-soluble carbohydrates, or fibre in these ingredients. Aquacult. Aquaculture includes seafood production from hatchery fish and shellfish grown to market size in cages, ponds and tanks. Hatcheries most aquaculture fish begin their lives in a hatchery. Given the heterogeneity of freshwater aquaculture systems, much of the recent literature focuses on system diversity, nutrition security, and value chains, particularly within the Asian context. As in many aquaculture systems, however, the application of carrying capacity models101,102,103,104 and routinely modified best management practices105 have continuously improved the sustainability of molluscan culture.
