大小选择性捕捞被认为会改变被开发鱼类种群的生活史，从而对种群生产力、恢复和产量产生负面影响。然而，要证明野生环境中由蜜蜂引起的表型变化至少部分是由基因决定的，已经证明是非常困难的。此外，对由进化引起的种群水平的后果的讨论仍有争议。使用实验方法，我们发现，五代大小选择性收获改变了野生斑马鱼（Danio rerio）的生活史和行为，但不是代谢率。鱼适应高积极的大小选择性捕捞压力投资更多的繁殖，达到一个较小的成年人的身体大小，并较少探索和大胆。表型变化似乎很微妙，但伴随着功能位点的遗传变化。因此，我们的研究结果提供了明确的证据，快速，收获诱导的表型和进化的变化时，收获是密集和大小选择性。根据生活史模型，所观察到的生活史变化提高了种群增长率在收获条件下，但减缓人口恢复下的模拟暂停。因此，大小选择性收获的进化遗产包括在开发条件下具有生产力的种群，但选择性地处于不利地位，以科普通常有利于大体型的自然选择压力。
Size-selective harvesting is assumed to alter life histories of exploited fish populations, thereby negatively affecting population productivity, recovery, and yield. However, demonstrating that fisheries-induced phenotypic changes in the wild are at least partly genetically determined has proved notoriously difficult. Moreover, the population-level consequences of fisheries-induced evolution are still being controversially discussed. Using an experimental approach, we found that five generations of size-selective harvesting altered the life histories and behavior, but not the metabolic rate, of wild-origin zebrafish (Danio rerio). Fish adapted to high positively size selective fishing pressure invested more in reproduction, reached a smaller adult body size, and were less explorative and bold. Phenotypic changes seemed subtle but were accompanied by genetic changes in functional loci. Thus, our results provided unambiguous evidence for rapid, harvest-induced phenotypic and evolutionary change when harvesting is intensive and size selective. According to a life-history model, the observed life-history changes elevated population growth rate in harvested conditions, but slowed population recovery under a simulated moratorium. Hence, the evolutionary legacy of size-selective harvesting includes populations that are productive under exploited conditions, but selectively disadvantaged to cope with natural selection pressures that often favor large body size.
