A collapsible swim-through trap having a cage body, a position lock mechanism, a release mechanism, and two setting hooks, the cage body having a front opening, a rear opening, and four walls extending between those openings. Each of the openings is equipped with a door which opens inwardly. There is a position lock mechanism used to secure the trap in an upright position which may be disengaged when a user wants to collapse the trap. The release mechanism includes a trigger, and an interfaced door retaining bar for holding the two doors in an open position. Upon pushing the trigger, the door retaining bar will rotate and release the two doors, trapping whatever is inside the cage body within the trap. The two setting hooks are used to hold the doors back while the door retaining bar is rotated into position.
