The development of demersal fishing in slope areas off southern Brazil (21o - 34o S) accelerated since the year 2000 as a result of commercial operations conducted by national and chartered bottom longliners, potters, gillnetters and trawlers. These operations were continuously monitored by observers as part of scientific research program carried out by the Fisheries Study Group (CTTMar - UNIVALI) in collaboration with Brazilian Government. Besides the assessment of the main stocks, efforts have been concentrated on assessing the impact generated by fishing on non-target organisms and on deep-water ecosystem as a whole. In this context, this work lists cephalopod fauna caught by both trawling and gillnetting between 2001 and 2003. Only the argentinean squid Illex argentinus was included between trawlers target-species, specially during the winter of 2001. Other 15 species, included in the orders Spirulida (1), Sepiolida (1), Teuthida (6) and Octopodida (5), were caught as by-catch of trawling operations. Particularly abundant in some fishing trips were the squid Pholidoteuthis adami and Histioteuthis corona corona, and the octopus Vosseledone charrua. Gillnet fishing directed towards the monkfish between 2001 and 2002 caught, besides the argentinean squid, two octopods including the pelagic Argonauta argo.Downloads
