When Releasing Reef Fish, Using The Right Tool, Right Technique Makes A Difference

With the right tool and the right technique, all anglers should properly descend or vent a fish and give them a better chance at survival.

When a fish survives release, it has another opportunity to reproduce and grow the population, leading to more fishing opportunities in the future.

Descending devices are tools with weights that attach to a fish and help take the fish back to the appropriate depth. There are various types of descending devices but the most common are lip clamps, inverted hooks, and fish elevators. It is important to find the device that works best for you.

Before you go fishing, be sure to have your selected descending device ready for use. To properly descend a fish with a lip clamp or inverted hook, attach the descending device and weights to a heavy-duty rod and reel that is designated for descending or use a rope to handline the device and weights down and back up.

A good goal is to use 1 pound of weight for every 5 pounds of fish being descended. Use a combination of loop knots, swivels, snaps, clips, etc. to attach the weights and device to your line. Be able to quickly and easily add or remove weights as needed, based on the size of the fish being descended and the water conditions. Unless you use a pressure-sensor device that releases fish automatically, you’ll need to jig your device to release the fish once the weights have brought it back down to depth.

To descend a fish with a fish elevator, simply send down the fish in a weighted container using a rope. This weighted container could be a crate, box or net that is turned upside down with an open top, so the fish can swim out on its own when it is returned to the bottom. 

Venting tools are sharp, hollow instruments that treat barotrauma by releasing expanded gas from the swim bladder, which enables the fish to swim back down to depth.

Items such as fillet knives, ice picks, screwdrivers and gaffs are not venting tools and should never be used to vent a fish. Venting a fish incorrectly can cause more harm than good. To properly vent, lay the fish on its side (on a cool, wet surface). Venting tools should be inserted 2-3 inches behind the base of the pectoral fin, under a scale at a 45-degree angle, just deep enough to release trapped gasses. Never insert venting tools into a fish’s belly, back or stomach that may be protruding from the mouth.

Descending devices and venting tools should be used when fish show one or more signs of barotrauma. It is essential to work quickly when using these tools and return the fish to the water as soon as possible to give the fish the best chance at long-term survival. Studies have shown that the longer a fish is out of the water, the higher the mortality rate. Therefore, it is important to minimize handling time when descending or venting a fish with barotrauma. Anglers should choose the device and method they are most comfortable with that best fits the situation, and that follows reef fish gear requirements.

When fishing for reef fish, descending devices and/or venting tools are required to be rigged and ready for use in Florida Gulf federal waters and descending devices are required to be on board and ready for use in Atlantic federal waters.
