Technique de pêche à la Palangre du Requin Sonneur (Lamna nasus Bonnaterre) et de l'Espadon (Xiphias gladius Linnaeus) en Atlantique Nord-Est

French fishermen have been fishing porbeagle shark Lamna nasus on the edges of the continental shelf, from the Bay of Biscay to the south of Ireland. Incidentally, until the past few years, when, during summer, bluefin tunas Thunnus thynnus, albacores Thunnus alalunga and sworfishes Xiphias gladius were caught on the same line. Since 1970, some fishermen have started focusing on swordfish. The authors describe the technique and gear used for this fishery. A fishery that could largely develop in the years to come.
