Empirical investigation into the applicability of surrogacy for juvenile salmonids (Oncorrhynchus spp.) exposed to hydropower induced rapid decompression

Surrogacy, whereby the response of a representative species subjected to a stressor is applied to one or more species, is commonly used without validation in conservation research and applications. The objective of this study was to empirically evaluate the appropriateness of using morphologically a...
