The purpose of this study was to develop a model to predict electroshock‐induced mortality in embryos of freshwater fishes. Herein, electroshock‐induced mortality was evaluated for sauger Sander canadensis and rainbow trout Oncorhynchus mykiss , and results were combined with published results obtained for eight other species in studies that used consistent methodology. The model was based on embryo diameter (1·1–4·1 mm among...
