CAPTAIN ROYS Fish Saver Descending Tool Fishermen often catch fish that are too small, out of season, not edible or they just do not want to keep. When these fish are reeled up from deep water, the changes in pressures cause the internal organs and swim bladder to expand, a condition known as fish barotrauma. If released, this condition prevents the fish from returning to its habitat causing the fish to die. This elongated barbless upside down hook, physically takes the fish back to the bottom, naturally recompressing the trapped air relieving the barotrauma effect, oxygenating the fish on the way down and releasing it unharmed. The device uses a weight to descend the fish and a retrieval line to bring it back to the surface. This device is simple with no moving parts or triggers and is capable of returning multiple fish at the same time. Features:
