Abstract(s)

The deep-sea sharks associated as by-catch of the Madeiran midwater drifting longline fishery for scabbardfishes (Aphanopus spp.) were investigated by means of an experimental survey at 800-1200 m depth within the Canary Islands Exclusive Economic Zone, whose fishing grounds have been exploited during the past 15 years. Nine species of chondrich thyans were identified, belonging to five families: Pseudotriakidae, Centrophoridae, Etmopteridae, Somniosidae and Chi maeridae. Data on length, weight and sex ratio for the 436 chondrichthyan individuals caught in the March 2009 survey are given. Several voucher specimens of each species caught were deposited in the collections of the Natural History Museum of Funchal.
Se investigaron los tiburones de profundidad en las capturas accesorias de la pesquería de palangre de deriva de media agua que tiene por objetivo el sable negro (Aphanopus spp.) mediante una campaña experimental en la Zona Econó mica Exclusiva de Canarias a profundidades de 800 a 1200 m, en caladeros que han venido siendo explotados en los últimos 15 años. Se identificaron nueve especies de condrictios pertenecientes a cinco familias: Pseudotriakidae, Centrophoridae, Etmopteridae, Somniosidae y Chimaeridae. Se aportan datos de talla, peso y proporción de sexos para los 436 ejemplares de condrictios capturados en la campaña de marzo de 2009. Los especímenes de referencia capturados fueron depositados en las colecciones del Museo de Historia Natural de Funchal.
