Carotenoid pigmentation in Salvelinus alpinus has been connected to stress responsiveness in earlier studies. This has, however, only been tested with time consuming image analysis from photos. Here, we used quick visual categorization of carotenoid pigmentation, to investigate the stress responsiveness of the extreme groups. The visually selected charr were then exposed to a net restraint stressor. Arctic charr with few spots also had a lower stress responsiveness compared to charr with many spots. Thus, visual selection could be used as a simple method within aquaculture. This article is protected by copyright. All rights reserved.

概念证明：北极红点鲑（Salvelinus alpinus L）类胡萝卜素色素沉着的视觉分类可以预测压力反应

Salvelinus alpinus 中的类胡萝卜素色素沉着与早期研究中的应激反应有关。但是，这仅通过对照片进行耗时的图像分析进行了测试。在这里，我们使用类胡萝卜素色素沉着的快速视觉分类来研究极端群体的压力反应。然后将视觉上选择的炭暴露于净约束应力源。与斑点多的北极炭相比，斑点少的北极炭也具有较低的应激反应能力。因此，视觉选择可用作水产养殖中的一种简单方法。本文受版权保护。版权所有。
