Fish reaction to electric pulses

I had done some research regarding the electrosensitivity of
elasmobranches
and as part of my study had included a green sturgeon also.  My results
were
inconclusive regarding the sturgeon as they had seemed not to be
susceptible
to electrical impulses generated in my experiment.  The sharks, however,
were much irritated each time I had "flipped the switch."

Hope this is of use.
