This paper shows CPUEs of Loligo gahi and Illex argentinus by Spanish vessels operating in the SW Atlantic from 1988 to 2001. The analysis of the raw data in a haul-by-haul basis indicated that the maximum CPUE for Loligo was obtained on the High Seas in March 2001 (6,372 kg/h), whereas for Illex, it reached 15,000 kg/h also on the High Seas in May 2001 (Division 42º S). Maximum mean monthly CPUE for Loligo almost reached 2,000 kg/h during August and September 2000 to the South of the Falklands (MS), as well as for Illex, a maximum value of around 2,700 kg/h was observed in February 2000 in Division 46º S. Both species are highly influenced by the oceanographic conditions of the area. Shortfin squid (Illex argentinus) performs yearly large migratory movements from the South of Brazil to Falklands, maybe related to its life cycle. Patagonian longfin squid (Loligo gahi) is more confined to a relative small area within Falklands waters, named Loligo-box, but with great explosions of abundance ...
