Data from: Carry-over effects of environmental stressors influence the life performance of brown trout

Here, we focused on the carry-over effects of excessive sedimentation on the early life stages of brown trout in a multiphase experiment. First, we experimentally tested the influence of fine sediments (organic matter (OM) and inorganic sand, both <2.0 mm in diameter) on the metabolic rate (MO₂), size, emergence, escape responses and survival of the relevant brown trout embryonic stage (egg, alevin or fry) in indoor experimental channels. Second, we mimicked the movements of parr to a more suitable habitat if available in natural rivers and transported parr to either their original or different treatments in outdoor experimental channels and remeasured their metabolic rate and size.本研究聚焦于多阶段实验（multiphase experiment）中，过度沉积对褐鳟（brown trout）早期生活史阶段的遗留效应（carry-over effects）。首先，我们于室内实验渠内开展实验，探究直径均小于2.0 mm的细颗粒物沉积物——包括有机质（organic matter, OM）与无机沙粒——对褐鳟相关胚胎阶段（卵、仔鱼（alevin）或稚鱼（fry））的代谢率（MO₂）、体型、出穴行为、逃逸反应与存活率的影响。其次，我们模拟了天然河流中幼鳟（parr）在存在适宜生境时向其移动的行为，并将幼鳟转移至室外实验渠的原处理组或异处理组中，重新测定其代谢率与体型。
