The Anglers Choice Venting/Fizzing Needle Tool is a 'must-have' tool for catching and releasing fish caught in deep water 50 feet or greater. This instrument is the device to vent a fish to reduce fish mortality rates! The fish venting tool addresses the condition of barotrauma, a condition where gases expand in the air bladder, causing a bloated belly, distended intestines, bulging eyes, or worse. The Venting/Fizzing Needle Tool alleviates these conditions. Insert the no-clog side vent needle under a scale 1-2 inches behind the base of the pectoral fin at a 45-degree angle and only deep enough to release trapped gasses. If a released fish can't swim back down on its own and shows one or more of the trauma symptoms, this is the perfect time to use your Anglers Choice Venting/Fizzing Needle Tool!Exclusive no-clog side vent needleSafety storage bungee-capDouble hilted no-slip gripQuantity per pack: 1Made in the USA
