Patent attributes
A trap accessory for attachment to a marine trap that facilitates release of by-catch. A buoyant recovery buoy is operably attached to a trap frame secured to the marine trap. Components for operably attaching the recovery buoy to the trap frame include a latch and attachment components, of which at least one of these components is a Degradable Metal (DM). The DM maintains the integrity of the trap and trap accessory for a pre-determined time, typically 1 year or less. When one or more of the DM components are sufficiently degraded, the recovery buoy is released to open a slot through which animals can escape. A buoy line connected to the trap frame maintains connection between the marine trap and the recovery buoy, which assists in recovery of the marine trap.
