To deploy the longline, an anchored line with a float and flag is fixed to each end of the mainline. The anchor ensures the gear stays on the ocean floor, while the flag, floating above the surface, marks the gear's position. The process begins by throwing the float and anchor overboard, followed by the mainline with its baited hooks, allowing it to sink to the seabed. The second float and anchor are then deployed, completing the setup.
The longline is left in place for several hours, allowing time for halibut, cod, and haddock to take the bait. After this period, the retrieval process starts by hauling in the float and anchor at one end. The mainline is then pulled into the boat, either manually or with the help of a rotating block or cylinder, especially for larger halibut.
As fish are pulled up, they are either flung onto the deck or removed from the hooks by hand, sometimes using a "gaff" – a large, unbarbed hook with a short handle. The line, now devoid of fish, is coiled into tubs for easy re-baiting and redeployment.
Longline fishing can cover extensive distances, often over a mile, making it highly productive. Recent advancements in gear technology and sustainable fishing practices have further enhanced the efficiency of longline fishing. The use of circle hooks, which reduce bycatch, and the implementation of GPS tracking for gear positioning have been significant improvements.
Moreover, regulations and quotas have been established to ensure the sustainability of halibut populations. Fishermen are required to report catches and adhere to strict guidelines to prevent overfishing. This balance between efficiency and conservation is crucial for maintaining healthy fish stocks and the long-term viability of the fishing industry.
In conclusion, longline fishing remains a vital method for catching halibut, cod, and haddock, combining traditional techniques with modern innovations to maximize efficiency and sustainability.
