US Patent 7874096 Fish releasing device

The present invention relates to a releasing device and more particularly a releasing device used to release fish in water. Deep-water fishes such as rockfish often exhibit the effects of rapid water pressure change such as expelled gas bladder, protruded eyes when brought to the surface. The fish releasing device of the present utilizes a jaw assembly, a weight, and other components to clamp onto a fish. The device is dropped into the water which pulls the fish beneath the surface of the water and automatically releases the fish upon the opening of the clamping jaw.
