An ice fishing trap including first and second securement struts, each having a plurality of securement chain receiving first holes. The device also includes an adjustable crossbar engaging at least an aligned pair of first and second apertures in the securement struts, a support bar on a bottom end of the securement struts, a removable trap conforming to a diameter of an ice fishing hole and having a barrier, and a trap retaining latch. The trap is secured in an open position by the engagement of the trap retaining latch. As a fish is reeled in through the hole, the fish disengages the trap retaining latch which releases the trap into a closed position at a bottom of the ice fishing hole. The barrier prevents the fish from escaping if the fish falls from a hook. The support bar prevents the trap from falling below the ice fishing hole.
