越来越多的证据表明，巨大的捕捞压力不仅导致鱼类资源枯竭，而且还导致鱼类种群发生进化变化。特别是，野生鱼类种群的体型和繁殖力可能会因渔业造成的高且通常具有体型选择性的死亡率而发生改变。虽然这些影响可能对鱼类种群的生存能力产生严重后果，但还有一系列与体型不直接相关的特征也可能影响渔具捕获的敏感性，从而影响渔业诱发的进化（FIE），但迄今为止一直被忽视。例如，在 FIE 的背景下，人们忽视了生理特征的变化可能会使物种内的某些个体更容易被捕获的可能性。具体来说，与能量平衡（例如，代谢率）、游泳表现（例如，有氧范围）、神经内分泌学（例如，应激反应性）和感觉生理学（例如，视敏度）相关的特征特别有可能通过各种机制影响捕捉的脆弱性。对这些性状的选择可能会导致种群内生理性状发生重大变化，以应对捕捞压力，这些变化尚未考虑，但可能会影响种群资源需求、恢复力、物种分布和对环境变化的反应。
There is increasing evidence that intense fishing pressure is not only depleting fish stocks but also causing evolutionary changes to fish populations. In particular, body size and fecundity in wild fish populations may be altered in response to the high and often size‐selective mortality exerted by fisheries. While these effects can have serious consequences for the viability of fish populations, there are also a range of traits not directly related to body size which could also affect susceptibility to capture by fishing gears—and therefore fisheries‐induced evolution (FIE)—but which have to date been ignored. For example, overlooked within the context of FIE is the likelihood that variation in physiological traits could make some individuals within species more vulnerable to capture. Specifically, traits related to energy balance (e.g., metabolic rate), swimming performance (e.g., aerobic scope), neuroendocrinology (e.g., stress responsiveness) and sensory physiology (e.g., visual acuity) are especially likely to influence vulnerability to capture through a variety of mechanisms. Selection on these traits could produce major shifts in the physiological traits within populations in response to fishing pressure that are yet to be considered but which could influence population resource requirements, resilience, species’ distributions and responses to environmental change.
