Unlikely, too many problems with electrical current dissipation in high
salinity water.  It would require a lot of current in the water to
maintain an electrical field which would also be dangerous.  Maybe there
would be a way to do it with fixed anodes in the water but you'd still
have to deal with how much current would required to maintain the field.

Subject: Re: Electrofishing workshops (boat and backpack)

Can electronic methods be used to create underwater electric fences for
in ocean inlets?

For example, could an electric fence be used under the Lions Gate Bridge
Vancouver to keep the salmon within Burrard Inlet as a huge closed 
containment tank? Or would other methods work better?
