Effect of Waveform and Voltage Gradient on the Survival of Electroshocked Steelhead Embryos and Larvae

Electrofishing is commonly used to monitor fish populations and to control nuisance or invasive fishes. These applications typically focus on juvenile and adult fish, and comparatively less is known about how early developmental stages of fish are affected by electroshock. We examined the survival of hatchery steelhead Oncorhynchus mykiss embryos and larvae exposed to three waveforms often emitted by commercially available electrofishing...
