That is actually an RPG , not a Bazooka. The RPG is an anti-tank weapon. What they should be using is a concussion grenade. The concusive force of the grenade is amplified in the water and kills the fish by literally scambling their brains. I don't the explosive force of the warhead of the RPG has enough "umph" to cause the concussion needed to kill fish. Besides, I'm not even sure those if those RPG warheads even travelled far enough to arm. Somebody with more extensive knowledge of the RPG will have to back me up on this.
