A safe and quick gas operated syringe that pierces the skull and brain of afish includesa hollow syringe in which a high pressured gas can be dispatched. The presentinvention places the end stop of the syringe perpendicular on to the skin orscales of thefish in which the brain is located. The needle is retained inside the syringevia a springand piston until the high pressure valve actuator induced gas forces theneedle out ofthe syringe and into the brain of the fish. A high pressure gas is expelledout of the endand sides of the needle causing complete brain destruction and immediate deathto thefish. A sealed gas cartridge is attached to an actuator which instantlypresentspressured gas into the syringe cylinder which plunges the piston with attachedneedleto the end stop of the syringe . The needle protrudes past the end stop of thesyringe ofwhich touches the fish head over top of the cranial area and penetrates thefish brain.The needle is the means in which high pressure gas is introduced to the brainmatter ofthe fish.The syringe uses a trigger exhaust valve to rapidly deploy highpressure gas tocylinder, piston, and through the needle into the fish brain andsimultaneously expelsthe high pressure gas from the syringe into the brain causing a quick andpainlessdestruction of the fish brain.Once the trigger is released the gas expelled through the needle and syringecylinderno longer has pressure to compress the return spring and the needle returnsinto thesyringe to the rest stop for safety and is ready for the next deployment.Thehighpressure cylinder can be easily installed or removed and can be utilized forseveralcycles with the use of the quick valve assembly.The present invention once placed on the brain area of the fish with the endstop willquickly and instantly upon activation of the device kill the fish.A piston shall be thick enough on the side walls in order to maintain thes
