Abstract
Abstract An underwater weapon principally for hand use for insertion into a fish after which upon operation of multidirectional release means in the form of a valve, fluid in the form of a liquid or gas is expelled into the interior of the fish causing the fish to become bloated and incapacitated for underwater mobility. The underwater weapon is provided with a hermetically sealed chamber to receive a removable flask containing fluid under pressure. A stiletto is provided on the forward end of the body and is provided with passage means in communication with the chamber so that upon puncture of the flask, the release of the fluid through the passage means in the stiletto may be controlled by the hand operated release means.
