The behavior of organisms can be subject to human induced selection such as that arising from fishing. Angling is expected to induce mortality on fish with bold and explorative behavior, which are behaviors commonly linked to a high standard metabolic rate. We studied the transgenerational response of brown trout (Salmo trutta) to angling-induced selection by examining the behavior and metabolism of 1-year-old parr between parents that were or were not captured by experimental fly fishing. We performed the angling selection experiment on both a wild and a captive population, and compared the offspring for standard metabolic rate and behavior under predation risk in common garden conditions. Angling had population-specific effects on risk taking and exploration tendency, but no effects on standard metabolic rate. Our study adds to the evidence that angling can induce transgenerational responses on fish personality. However, understanding the mechanisms of divergent responses between the populations requires further study on the selectivity of angling in various conditions.

父母的垂钓选择是否会影响鳟鱼的行为或新陈代谢？

生物的行为可以受到人为选择的影响，例如捕鱼引起的选择。钓鱼有望以大胆和探索性行为诱发鱼类死亡，这些行为通常与高标准代谢率相关。我们通过检查实验蝇钓是否捕获到的父母之间的1岁幼崽的行为和新陈代谢，研究了褐鳟（Salmo trutta）对钓鱼诱导选择的跨代反应。我们在野生和圈养种群上进行了成角度的选择实验，并比较了在普通花园条件下具有掠食风险的后代的标准代谢率和行为。垂钓对冒险和探索趋势有特定的影响，但对标准代谢率没有影响。我们的研究为钓鱼增加了对鱼类个性的跨代反应的证据。但是，了解种群之间差异反应的机制需要进一步研究各种条件下钓鱼的选择性。
