The System of National Accounts (SNA) recommends using GVA at basic prices for this purpose. The difference between total industry GVA and total GDP is taxes less subsidies on products, which varies across countries. This adjustment is made at the aggregate (total economy) level because, while time series of taxes less subsidies on products may be available by product, they are not generally available by industry. Furthermore, it should be noted that this study took the year 2010 and Revision 3 of the International Standard Industrial Classification of All Economic Activities (ISIC) as baselines in order to maximise the completeness, consistency and comparability of available data. The other industries accounted for shares of 5% or less (Figure 1.2). While the share of industrial capture fisheries is small (1%), it should be noted that inclusion of estimates of the value added generated by artisanal capture fisheries (mainly in Africa and Asia) would add further tens of billions of USD to the capture fisheries total (see Chapter 6 for detailed estimates).
