摘要：

Exponential pulse waveform in electric fishing gave a significantly poorer capture efficiency than other waveforms evaluated. Plasma cortisol levels were significantly and uniformly elevated after shocking by all waveforms. Mortality from the electric fishing was low, 0.2% overall, with few sub-lethal effects. A 0.5 ms duration square pulse waveform had significantly higher catch-per-unit-power than the other waveforms. (C) 2000 The Fisheries Society of the British Isles.
