The Harvest Gear
Canada’s commercial fishermen mainly use longline gear when harvesting wild Pacific halibut.
In some parts of the world there are fisheries with large longline vessels capable of deploying groundlines up to 80 kilometres (50 miles) in length; however, Canada's wild Pacific halibut fishery is a small-boat fishery and the groundlines used are much shorter, generally less than 2 kilometres (1.25 miles). Longline gear includes a long line, called a groundline, with baited hooks attached at intervals with branch lines called gangions. A gangion is a short length of line attached to the main line with the baited hook at the other end. Each groundline is attached to an anchor and buoy line on one end and marked at the surface with a buoy, flagpole and flag.
