FYI: Why Do We Hate The Sound Of Nails On A Chalkboard?

Screeeeeeeech! Most people associate this cringe-worthy noise with words like “piercing” and “shrilling.” But it isn’t actually the sound’s high-pitched tones that give us goose bumps. During a study that dates back to 1986 (the days when…

Halpern et al. reply

replying to T. A. Branch, D. J. Hively & R. Hilborn. Nature 495, http://dx.doi.org/10.1038/nature11974 (2013)
Branch et al. suggest that the fisheries component of our ocean health and benefits index is ‘biased’. We contend that our approach is no more biased than their alternative, and that our method improves on theirs in three fundamental ways: it provides a score for every country, accounts for thousands of data-poor stocks, and incorporates sustainability more comprehensively.

Is the ocean food provision index biased?

arising from B. S. Halpern et al. Nature 488, 615–620 (2012)
How close to maximum sustainable food provision is current seafood harvest from the world’s oceans? Halpern et al. suggest that the answer is 25% from a global index of food provision, part of their multifaceted index of ocean health. Rigorous methods used for management, however, demonstrate that their food provision index is uncorrelated with actual food provision, and that global ocean food provision is in the range of 71–95%. Their results stem from an uncertain method of estimating maximum sustainable yield (MSY), and we believe that this approach should be avoided as a measure of food provision.
