how does aquaculture affect worldwide seafood catch

Technol. Sci. by Hannah Ritchie September 13, 2019 Global production of fish and seafood has quadrupled over the past 50 years. Kim, G. H., Moon, K.-H., Kim, J.-Y., Shim, J.

The seaweed hydrocolloid industry: 2016 updates, requirements, and outlook. Even in sectors in which major investments and progress have been made in the detection, avoidance, and treatment of PPP, new threats frequently emerge. 21, 4762 (2020).This study provides field-based evidence on the extent of feed-grade, non-targeted fish catch in China for aquaculture feeds and its implications for marine food webs. View this answer. J. Appl. Sci. Such science-led disease management options remain largely unavailable for many low-value aquaculture species and low-income regions owing to a lack of product development and prohibitive costs. b, c, Growth is shown from 1997 to 2017 forthe following production categories (b): total, freshwater fish, algae, molluscs and CDMM, which comprises crustaceans, diadromous fish, marine fish, and miscellaneous species and is expanded in c. Algae comprised more than 99% of the production weight of algae and aquatic plants production in 2017. 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.

The development of aquaculture in the new era from a multi-dimensional perspective. Resour. Sci. These three trends result in a sector tightly integrated into terrestrial food systems via feed, nutrient cycling, and value chains. 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. Many terrestrial feed ingredients for aquaculture are by-products, such as oilseed protein concentrates extracted from the processing of food products, or protein meals and oils recovered from the processing of livestock and seafood (including aquaculture)43,59.

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. Bush, S. R. et al. In 2017, aquaculture supplied more than 80Mt of fish and shellfish and 32Mt of seaweeds, encompassing around 425 farmed species2. Although improper therapeutant use can pose risks to the health of consumers, workers, cultured organisms, and surrounding ecosystems (particularly in open production systems)96,142, the misuse of antimicrobials in aquaculture is especially problematic as it can lead to the emergence and transfer of antimicrobial-resistant genes and bacteria140. Earth Environ. Gentry, R. R. et al. Int. 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). In summary, as the global industry continues to expand, its contribution to economic social and environmental performance varies across a wide diversity of aquaculture systems. https://doi.org/10.1080/23308249.2020.1795615 (2020). S.E.S. 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.

Impacts of Climate Change on Fisheries and Aquaculture: Synthesis of Current Knowledge, Adaptation and Mitigation Options. Proc. Adoption of best management practices (for example, for site and system selection, stocking densities, species rotations, broodstock, and feed quality, filtration, pond, and cage cleanliness, parasite monitoring and removal, culling, zoning, and surveillance) has been the most important means of minimizing PPP risks across all types of production systems25,134. Crona, B. et al. 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. Alleway, H. K. et al. A review of inclusive business models and their application in aquaculture development. Numerous studies have highlighted the micronutritional and sensory attributes of seaweeds for direct human consumption111 or as functional foods112, but benefits are difficult to quantify because of variation across species, seasons, and coastal environments, and a lack of clear scientific evidence regarding nutritional bioavailability and metabolic processes associated with algal consumption110.

This paper reviews the science on climate impacts on the aquaculture sector. Aquacult. ADS Certified and rated production is skewed to major export species. Wang, J., Beusen, A. H. W., Liu, X. They may also enable greater transparency and trust of aquaculture products exported from developing countries and create inclusive improvement pathways for the 90% of aquaculture output that is not directed towards export markets. Annu. 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 producers seeking to market sustainable products are therefore faced with the unintended environmental and social consequences of their feeding practices. Belton, B.
