捕鱼相关的选择是人类对自然种群最重要的进化压力之一。然而，目前还不清楚捕鱼是否会导致目标种群中的遗传表型变化，因为可能受到选择的性状的遗传力和遗传相关性很少受到关注。此外，表型变化可能来自捕捞相关的环境影响，如人口密度的降低。使用鱼类饲养在基线和减少组密度和重复收获的模拟拖网，我们表明，拖网可以诱导直接选择鱼类的社会行为。由于社会性具有很大的遗传性，而且在遗传上与活动和探索有关，拖网捕捞有可能对各种鱼类行为造成直接选择和间接选择，从而有可能随着时间的推移而导致进化。然而，拖网捕捞选择是一致的密度条件下，遗传力和遗传相关的行为发生变化，根据人口密度。因此，与捕鱼相关的环境影响可以改变鱼类行为的进化潜力，这表明需要使用更综合的方法来解决捕鱼的进化后果。
Fishing‐associated selection is one of the most important human‐induced evolutionary pressures for natural populations. However, it is unclear whether fishing leads to heritable phenotypic changes in the targeted populations, as the heritability and genetic correlations of traits potentially under selection have received little attention. In addition, phenotypic changes could arise from fishing‐associated environmental effects, such as reductions in population density. Using fish reared at baseline and reduced group density and repeatedly harvested by simulated trawling, we show that trawling can induce direct selection on fish social behaviour. As sociability has significant heritability and is also genetically correlated with activity and exploration, trawling has the potential to induce both direct selection and indirect selection on a variety of fish behaviours, potentially leading to evolution over time. However, while trawling selection was consistent between density conditions, the heritability and genetic correlations of behaviours changed according to the population density. Fishing‐associated environmental effects can thus modify the evolutionary potential of fish behaviour, revealing the need to use a more integrative approach to address the evolutionary consequences of fishing.
