Bear in mind that fish are very sensitive to metals.

And sensitive to electricity?
Even a few millivolts?
I've heard of electric fishing lures and/or methods of 'attracting" (or
driving) pond fish towards electrodes placed in the water!
And none of these involve 'shocking' the fish into insensibility?




Yes they can be, Terry. Marine fish and certain species of
freshwater fish can become unwell in the presence of electric
currents. Hence, my earlier suggestion of making sure that any
sensing electronics is very high impedance.
