![]() Venting tools should be inserted at a 45-degree angle, under a scale 1-2 inches behind the base of the pectoral fin, just deep enough to release trapped gasses.ĭescending devices and venting tools should only be used when fish show one or more signs of barotrauma and cannot swim back down on their own. Never insert venting tools into a fish’s belly, back or stomach that may be protruding from the mouth. ![]() Insert the venting tool at a 45-degree angle, under a scale 1-2 inches behind the base of the pectoral fin, just deep enough to release trapped gasses. To properly vent, lay the fish on its side (on a cool, wet surface). Venting a fish incorrectly or with the wrong tool may cause more harm than good. Please note, items such as fillet knives, ice picks, screwdrivers and gaffs are not venting tools and should never be used to vent a fish, because they are not hollow tubes that allow air to escape. Venting tools are sharpened, hollow instruments that anglers can use to treat barotrauma by releasing expanded gas from the swim bladder, enabling the fish to swim back down to capture depth. Learn more about descending devices and how to use them at /SaltwaterFishing by clicking on the “Fish Handling” then “How-to Videos” or scrolling to “Barotrauma.”ĭescending devices are used to return fish to a depth where expanded gases in the body cavity can recompress. They fall into three categories: mouth clamps, inverted hooks and fish elevators. It’s important to know in advance what tools are available and how to use them to help fish return to the bottom and increase their chances of survival.ĭescending devices can be used by anglers to take fish back down to depths where increased pressure from the water will recompress swim bladder gases. Signs of barotrauma include the stomach coming out of the mouth, bulging eyes, bloated belly and distended intestines. Barotrauma is a condition seen in many fish caught in waters greater than 50 feet that is caused by expansion of gases in the swim bladder. Continue your role as a conservationist by looking out for fish with signs of barotrauma and being prepared to respond. ![]() It’s that time of year when you might be fishing for snapper and grouper.
