Research in recent decades has explored the potential for seaweeds to substitute for terrestrial crop and animal production in protein, fat (omega 3) and energy intakealleviating pressure on freshwater and land resources and biodiversitybut there is little evidence to date that seaweeds can contribute substantially to human macronutrient intake110. Given large capital costs and high risk-to-return ratios, offshore aquaculture in other countries has been confined mainly to small-scale pilot operations cultivating high-valued, carnivorous species. serves on the Advisory Committee on Aquaculture Science for DFO Canada (http://www.dfo-mpo.gc.ca/aquaculture/advisory-comm-consultatif-eng.html). Nature 405, 10171024 (2000). Aquaculture producers have responded by reducing the use of fishmeal and fish oil in feed formulations, and these efforts have been reinforced by sustainability goals throughout the supply chain. Article Aquaculture producers seeking to market sustainable products are therefore faced with the unintended environmental and social consequences of their feeding practices. Aquaculture's share of the forage-fish catch has nearly doubled since 2000. Although the production of marine and diadromous fish species and crustaceans has also grown rapidly during this period, it has been dwarfed by the live-weight volume of marine bivalves and seaweeds, and by the production of freshwater aquaculture. Aquacult. 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. J. Phycol. Applications of recirculating aquaculture systems within raceways and channelled pond systems for shrimp aquaculture are also cost-effective in many farming areas given high disease and water-quality risks148. Nutrient extraction has two modes: harvest and removal of the bivalves, and increased denitrification near dense populations of wild or farmed bivalves. 64, 5264 (2014). 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.

At the time, the commercial aquaculture sector was flourishing, whereas the production of capture fisheries remained stagnant. Low levels of compliance have been attributed to insufficient finances, low demand for certified products, poor literacy levels, and inadequate administrative skills required for monitoring and reporting192,193, and environmental production risks beyond the control of the producer194.

J. The industry remains fragmented outside Asia (mainly China and Indonesia), and competitive pricing constrains net revenues and incentives for innovation108. 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. Recycling processed by-products and food wastes into high protein feed ingredients contributes to the sustainable production of food globally, but life-cycle analysis is needed to measure the net environmental impact.

Food safety risks are therefore high for molluscs cultivated in polluted environments. Aspirations to improve the environmental and social performance of aquaculture practices and technologies have led to the emergence of new combinations of public and private regulation, codes and standards187; however, the application of these governance instruments has struggled to match the expanded geographies, volumes, and diversity of aquaculture systems188.

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. By transitioning to more sustainable fishing methods, fishermen can preserve or rebuild our remaining wild stocks, limit the bycatch of other wildlife and protect ocean habitats. Seaweed aquaculture lags behind other food sectors in breeding, pathogen management, and optimization of production systems for nutrient, light and temperature conditions83. 27, 638651 (2020). Google Scholar. Rev. Google Scholar. Int. Sci. Aquaculture 493, 338354 (2018). Since 2000, there has been a growing appreciation for algae (dominated by macroalgae or seaweed) for improved nutrition, industrial use, and ecosystem services, even in regions outside China, Japan, Korea, and parts of South America, where seaweeds have been consumed as food for centuries83,106,107. J. China alone supplied 58% and 59% of the global aquaculture volume and value, respectively, for all categories combined in 2017 (Extended Data Table 1).

Fisheries in transition: food and nutrition security implications for the Global South. Fish Fish. Global networks, such as the World Organization for Animal Health, have emerged to facilitate the transfer of scientific knowledge. The global production of aquatic plants and algae has tripled from 10Mt of wet biomass in 2000 to more than 32Mt in 2017, with aquaculture contributing more than 97% of the current volume17,106. Aquaculture is more diverse today, with 40% more fish, shellfish, aquatic plant, and algal species cultivated in a wide variety of marine, brackish, and freshwater systems globally10.
