Learn how to properly use descending devices They also require more equipment, including a designated rod and reel on the boat to decrease the time between catch and release. weighted milk crateĭescending devices require less training and have the potential to cause less harm to the fish than using venting tools. Once at depth, the fish swims out from under the crate or net, which can then be pulled back to the surface. Due to the need for rope, this method is not always ideal for returning a fish to the depth where it was caught, but studies have shown that getting a fish down to at least 90 feet starts the depressurization process and increases the fish’s survivability. Fish are placed underneath the crate or net and lowered with a rope to depth. seaqualizerĬreated by adding weights to a milk crate or a drop crab net, these devices provide more protection from predators as the fish descend. Once the fish is lowered and reaches the pre-set pressure, the clamp automatically opens and releases the fish. The clamps are attached to a rod and reel along with the weight necessary to reach the depth where the fish was caught. Similar in design to the weighted hook or clamp, these devices use pre-set, pressure-activated clamps to return the fish to depth. diy weighted clamp using a fish grip diy inverted hook shelton fish descender roklees - the fish descending device Pressurized release. Once at depth, a quick tug on the rod will release the fish. They are tied to a rod and reel with heavy enough weight attached to get the fish back down to the depth where it was caught. These devices use an inverted barbless hook or a clamp to hold the fish. Photo courtesy of Florida Fish and Wildlife Conservation Commission. There are many types of descending devices that anglers can make at home or purchase. As the fish descend, their swim bladders naturally decrease with the increase in pressure. Anglers should assess each fish individually to determine if they need descending assistance and choose a method that they are comfortable using.ĭescending devices offer non-invasive options for anglers to depressurize fish by sending them back down to depth and allowing their swim bladders to return to size naturally. What Anglers Can Do to Reverse BarotraumaĪnglers can use descending devices or venting tools on fish showing signs of barotrauma.
