Journal Article
Is the ocean food provision index biased?/Halpern et al. reply
2013
Overview
Re-sampling fisheries from FAO ranges for overexploited fisheries, fully exploited fisheries and underexploited fisheries3 and estimating food provision using the Pella-Tomlinson model yields a mean food provision index of 82% (95% CI, 81-84%). [...]food provision from oceanic fisheries is consistently estimated to be in the range of 71-95% by a wide variety of methods, which is far from the 25% estimated by Halpern et al.1. [...]Halpern et al.1 believe that it must be possible to extract MSY and food provision estimates from a simple function of current catch and maximum catch.
