Resumo: | Data obtained by observers on board of two fishing vessels during six trips carried out between January-April 2010 to catch tuna were analyzed. Thirty-four fishing days were completed and of the 59 trawls performed 37 turned out positive (with tuna catches). The fishing gear consisted of a purse seine net. Exploitation took place within the Argentine-Uruguayan Common Fishing Zone, between 36° S-39° S. The main landings occurred in March and consisted of slender tuna, Allothunnus fallai (57%), followed by albacore, Thunnus alalunga (28.5%), in January and bonito, Sarda sarda (14%), in April. Sea surface temperature ranged 16 °C-19 °C. A total of 25 length frequency samples allowed to measure individuals of the species above mentioned and those of skipjack tuna (Katsuwonus pelamis). During fishing operations the death of some magellanic penguins (Spheniscus magellanicus) and soft-plumaged petrels (Pterodroma mollis) as well as catch of anchovy (Engraulis anchoita) were registered
