Seining

Long Lines for a Purse Seiner

Purse seining is well known as one of the most effective technologies for demersal fisheries. Today many nations support extensive fleets of 20 to 30-meter wood, steel, fiberglass or aluminum vessels working with nets that range of 500 to 1000 meters in length. Throughout Malaysia and Thailand, even in the wooden boat fleet, these vessels are typically equipped with sonar and Puretic-style hydraulic power-blocks for hauling back the nets. All of this was evidenced on a recent visit to the F.V. Sombatpomae owned by Khun Thayuth, who recently acquired it from a processor. The 20 by 7-m wood purse seiner was built 20 years ago in Mahachai on the Gulf of Thailand and brought around Singapore and through the Straits of Malacca to the Thai Andeman Sea port of Ranong. The boat’s crew was busy working to splice what looked like short 18-in. ganglions into skates of half-inch ground line. Captain Mien Saeguay (known to the crew as Capt. Dum) quickly explained that these were not ground-lines and it would be coconut husks, not hooks that would be affixed to the gear. The boat fishes mackerel and various small local tunas in waters of 30 to 70 meters. Species include plaa oh dum (tonggol tuna), plaa oh lai (Thai skipjack or euthynnus) and plaa ta toh (big eye). The lines, with a small forest of coconut husks attached, are deployed between bamboo-pole-marked floats at the surface and concrete-filled bucket anchors. They are arranged in a 10-m diameter circle of 15 lines


New Alaska Limit Seine Boat

For many years Alaskan salmon purse seiners have been limited to a length of 58 ft. This led to the development of some beautiful and relatively beamy wooden boats in the 1950s. In the intervening decades designers have fine-tuned the 58 ft design to add beam and depth. An example of this is being built at Westman Marine in Blaine Washington to a design by Hockema & Whalen Associates Inc. of Seattle and Bellingham Washington


Box: Generations on An Alaskan Limit Seiner

Petersburg, Alaska has been known since its founding as the home of good fishermen and fine boats. One of the earliest limitations on the commercial salmon fishery was the limiting of Alaskan seine boats to 58 ft. Over time, the Alaska limit seiner evolved to one of the truly classic fishboats of the world. With its high bulwarks over a plum bow stem and a full body flowing with a clean shear aft to a broad timbered stern
