I claim:

1. A submersible barrier for shielding a portable manually manipulatable anode electrode of a pair of anode and cathode electrodes used with portable electrofishing apparatus to be supported by an operator, which apparatus includes an electric circuit unit electrically connected with the anode and cathode electrode for providing DC pulses, said barrier comprising in combination:

a) a wall disposed about the portable anode electrode for shielding the portable electrode against contact by the operator or other objects when the portable anode electrode is out of the water and for shielding the portable anode electrode against contact by the operator, fish and other objects when the portable anode electrode is in the water;

b) means for accommodating water flow through said wall to establish an electric field in the water surrounding the portable anode electrode;

c) means for securing and maintaining said wall about the portable anode electrode when the portable anode electrode is manipulated into and out of the water by the operator; and

d) means for transporting said electrofishing apparatus during use of said electrofishing apparatus.
