A Fish and Crustacean Trap Escape Vent System, consisting of an inexpensive conical-shaped escape vent with minimal water current noise or resistance, which presents a diminishing perspective to fish and crustaceans in the trap, secured to the trap with Coded, Corrosive-Release Fasteners of different diameters, thereby allowing for easy recognition by fishermen and enforcement authorities of which diameter of fastener is in use. Coding means includes offsets, crimps or color-coating imparted to different Fasteners. If the trap is lost or unrecovered for a predetermined time, the Coded Corrosive-Release Fasteners completely disintegrate and allow the Escape Vent to detach from the trap and allow any trapped fish and crustaceans to escape the trap. The unrecovered trap is now theoretically prevented from further fishing. The Escape Vent remains attached to the trap by conventional hog rings, and can be reused if and when the trap is recovered. Corrosive-Release Fasteners of different diameters and/or compositions can be tested in each locale. Regulations can then specify the wire diameter, composition, and method of coding the Corrosive-Release Fastener which is to be used in specific geographic areas.
