Releasing Fish Caught from Deep Water
Descending Devices
A descending device (recompression device) is a tool that is used to reverse the effects of barotrauma. The device descends fish back down to a depth where the increased pressure from the water will recompress the swim bladder gases and allow the fish to swim away. In recent years, a number of descending devices have been developed. The type of descending device to use is often based on individual angler preference.
Most devices are weighted and attached to fishing line (or rope) and clamp or hook on to the mouth of the fish. The angler lowers the device and fish back down to a depth where the fish can recover from barotrauma and then releases the fish. Another option is a fish elevator, a bottomless cage which allows the gases to recompress while the fish is brought down to capture depth.
Although more research is being conducted, there are indications that use of descending devices can increase survival of released fish. If you choose to use a descending device, follow the instructions on the package carefully to ensure the device is used properly. Watch our descending devices playlist to learn more.
