According to aspects described herein, there is disclosed an apparatus for killing a soft tissue organism in a salt water environment. The apparatus includes an elongate tubular housing, a probe and a conductive element. The elongate tubular housing reaches from outside a salt water environment to at least a portion of a soft tissue organism disposed within the salt water environment. The elongate tubular housing includes a proximal end and a distal end. The probe targets the soft tissue organism, The probe protrudes from the distal end of the housing, wherein the probe is exposed to the salt water environment when the distal end is submerged therein. The conductive element is rigidly supported by the housing between the distal end and the proximal end. The conductive element is exposed to the salt water environment when the housing distal end is submerged therein. The probe and the conductive element being operatively coupled to a source of electric current, such that the salt water environment provides a circuit coupling between the probe and the conductive element for killing the soft tissue organism.
