SUBMERGING A BUOY UNDERWATER to avoid traffic, detection by other fishermen or to prevent poaching. Numerous methods are used to rig up the line and buoy. Care must be taken in rigging up the coiled line to prevent any tangles when the GTR releases the line and buoy. Check local regulations to insure compliance.
PREVENTION OF GHOST FISHING TRAPS is achieved by using GTR's to activate an escape mechanism such as an escape door or escape panel. The use of GTR's to prevent ghost-fishing pots offers a "time certain" method that allows visual inspection. This is not available with untreated cotton twine or untreated metal hog rings.
GEAR RETRIEVING SYSTEMS use GTR's as timing devices to release a retrieval line and hard plastic buoy. Such systems can be used on pot gear as well as longline gear.
TIMED BAIT RELEASE CONTAINERS can be activated using GTR's. They allow the pot to be rebaited without pulling the pot. This is especially useful on longer soaks caused by delivery schedules or bad weather. They can also be used in areas where sea lice are a problem.
