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.

[ What is claimed is:] [1.] In a sea-water or fresh-water fish or crustacean trap having a lattice work side or top structure, an escape vent system comprising:(a) an escape vent of molded plastic material to replace a top or side portion of the fish or crustacean trap lattice work, said escape vent having substantially cylindrical and parallel upper and lower frame members with at least one securing tab disposed upon said upper and lower frame members, two substantially parallel side frame members, a plurality of webbing members extending from, and situated between, said frame members and at least one ring located substantially in the center of said escape vent for selectively defining a fish or crustacean escape hole;(b) securing means for pivotably attaching said escape vent to the side or top of said fish or crustacean trap, said securing means comprising at least one non-corrosive fastener;(c) additional securing means for detachably attaching said escape vent to the side or top of said fish or crustacean trap, said additional securing means comprising at least one corrosive-release fastener of predetermined diameter; and(d) identifying means for coding said predetermined diameter of said corrosive-release fastener, said identifying means for coding identifying the at least one corrosive-release fastener and its corresponding predetermined fastener release time from different corrosive-release fasteners,whereby said escape vent remains fully attachable to said trap and functions to allow undersized trapped fish and crustaceans to escape through said escape hole during normal usage, and whereby said at least one corrosive-release fastener will disintegrate after said predetermined release time and allow said escape vent to pivot away from said side or top of said trap, allowing all fish and crustaceans to escape when said trap remains unrecovered after said predetermined release time.
