Fish descending device
A descending device including a member providing a fish attachment point, a member providing a means of traversing the suspension point, a moveable member to attach the suspension line and traverse to the alternate suspension point, a member that applies a moment about a suspension point to reverse the orientation of the device and stops that prevent the attachment member from coming off the descending device.
1. A method for returning a fish to depth so the fish can recover from barotrauma, the method comprising:
providing a device for returning a fish to depth so the fish can recover from barotrauma, the device comprising:
a rigid wire having a proximal end and a distal end;
a hook disposed on the rigid wire at the proximal end;
a weight fixedly attached to the rigid wire at the distal end; and
a sliding member disposed on the rigid wire in sliding relation between the proximal end and the distal end;
providing a suspension line attached to the device at the sliding member;
attaching a fish onto the hook of the device, the fish hanging by its lower lip on the hook and the sliding member in a first point of suspension, with both the fish and the weight below the first point of suspension;
lowering the device with the attached fish into the water;
moving of the sliding member to a second point of suspension by the weight acting on the device with the fish lagging due to its buoyancy;
turning of the device into an upside-down position by action of the sliding member sliding to the second suspension position;
pulling of the fish to a lower depth by the device; and
exerting an upward pull on the suspension line upon reaching the lower depth thereby pulling the hook out of the fish's mouth, whereby the fish has been returned to depth and recovered from barotrauma.
