'Ask the author series' är ett initiativ från Table, som är ett samarbete SLU, University of Oxford, och Wageningen University and Research. 

"Ask the author"-seminarierna ska ge möjlighet till en fördjupad diskussion om forskningen och dess konsekvenser för deltagare från olika discipliner och sektorer. Varje session har plats för upp till 25 aktiva deltagare, som ombeds läsa artikeln och förbereda kommentarer eller frågor i förväg. Evenemanget streamas via Zoom Webinar, där Q & A-funktionen används för frågor, kommentarer och inspel till diskussionen.

Nästa tillfälle, den 30 april, diskuterar Nature-artikeln A 20-year retrospective review of global aquaculture

Read TABLE's summary of this publication.


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. This paper reviews the developments in global aquaculture from 1997 to 2017, incorporating all industry sub-sectors and highlighting the integration of aquaculture in the global food system. Inland aquaculture—especially in Asia—has contributed the most to global production volumes and food security. Major gains have also occurred in aquaculture feed efficiency and fish nutrition, lowering the fish-in–fish-out ratio for all fed species, although the dependence on marine ingredients persists and reliance on terrestrial ingredients has increased. The culture of both molluscs and seaweed is increasingly recognised for its ecosystem services; however, the quantification, valuation, and market development of these services remain rare. The potential for molluscs and seaweed to support global nutritional security is underexploited. 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. 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.
