All previous opinions here on DIY electrofishing by in-the-know folks have been negative. Dangerous stuff to try and rig up yourself.
To quote ewest:
Boat mounted e-fishers should only be used by experienced operators - way to dangerous for others and the fish. Back pack e-fishers are for very limited use in small streams and waters and can be very dangerous.
TY Theo - this kinda sets me straight on my thought electrofishing would be a magical process. I'm still concerned with how I'm going to seine fish effectively - guess lowering the water levels and wading after them is going to be my best bet. Sigh.
