Transparency in aquaculture subsidy reporting urgently needed

In this special issue of Science Advances, Quaade et al. (1) report that aquaculture (i.e., fish farming) production data are 'sparse, self-reported, and aggregated' and that this limits the effective understanding and monitoring of the industry’s trends and potential risks. The authors then build a manual survey of aquaculture production from remote sensing imagery. If aquaculture production data are sparse, then data on the amounts and types of subsidies provided to the sector are almost nonexistent. By U. Rashid Sumaila
