Pershing et al (Reports, 13 November, p. 809) concluded that failure to account for temperature in the assessment and management of Gulf of Maine Atlantic cod caused overfishing. We argue that the "extra mortality" calculation driving this conclusion is an artifact. Environmental factors affect all stocks, but attribution of additional mortality to temperature alone by Pershing et al is unsupported by the data.
珀欣等人（报道，11 月 13 日，第 809 页）得出结论，在评估和管理缅因湾大西洋 cod 时未能考虑到温度，导致过度捕捞。我们认为，推动这一结论的“额外死亡率”计算是一种假象。环境因素会影响所有种群，但珀欣等人仅将额外死亡率归因于温度，这一说法并没有得到数据的支持。
