Description

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.
