Portuguese Longline (Gangion)
The Portuguese longline is a fishing technique that involves using a long fishing line anchored to the seabed and buoyed at the surface by a vessel or a buoy. This method is primarily used for catching species that inhabit the deeper waters of the ocean. It is a variation of the traditional longline fishing technique and is known for its efficiency in targeting specific fish species while minimizing bycatch and environmental impact.
The Portuguese longline fishing technique operates as follows: A main fishing line, known as a longline, is deployed from a fishing vessel or buoy, consisting of smaller branch lines attached to it. This mainline, often constructed from durable materials like monofilament or braided line, can extend over several kilometers. Anchored to the seabed using weights or anchors, the mainline stretches along the ocean floor, allowing branch lines, each featuring hooks and bait, to hang at varying depths above the seabed. Floats or buoys at the surface keep these branch lines suspended vertically in the water column, with their positioning determining the desired depth for the hooks and baited lines. These hooks, adorned with a variety of bait to attract specific fish species, are evenly spaced along the branch lines to enhance catch opportunities. As the vessel moves, the baited hooks' movement and aroma entice fish to the fishing line. Upon capturing fish on the hooks, the longline is reeled in, and the harvested fish are carefully removed from the hooks. This process continues until the desired catch is achieved.
The Portuguese longline fishing technique stands as a beacon of sustainability and responsible seafood consumption, captivating consumers who seek ethical and eco-conscious choices. Distinguished by its precision in targeting specific fish species through depth adjustment and bait selection, it substantially reduces bycatch, setting it apart from conventional methods. Moreover, its low impact on marine habitats compared to techniques like trawling showcases its commitment to preserving fragile ecosystems. With minimal gear loss and ghost fishing potential, traceability from catch to plate is enhanced, assuring consumers of both responsible sourcing and superior seafood quality. By aligning with sustainable fisheries management principles and advocating for marine biodiversity conservation, the Portuguese longline technique resonates with consumers keen on fostering healthy oceans.
