Abstract: An ice cooler for storing and refrigerating caught fish has a removable top lid provided with an insert having separated teeth to seal the lid and thereby the cooler. The teeth retentively engage the body of a hooked fish disposed tail-first therewith preparatory to the fish being unhooked by a fisherman for the fish's own downward movement through the engaging teeth and into the cooler by the fish's own force of gravity. The teeth have their own memory to spring-back to re-seal and close the lid upon cessation of physical contact with the fish.
