The present paper reconstructs total marine fisheries removals in the Exclusive Economic Zone (EEZ) of Argentina from 1950 – 2010 by providing estimates of unreported components of fisheries catch in various sectors. The results indicate that reconstructed catch is 55% higher than FAO reported landings. Of the unreported component, unreported commercial landings accounted for 61.1%, discards accounted for 24.0%, recreational catch accounted for 14.7%, and catch in the subsistence sector was 0.2%. The recent declines in catch and the shift to species of lower trophic levels point to over-exploitation of Argentinean fisheries.

Total reconstructed catch was estimated at 38,600 t in 1950, increasing to 81,200 t in 1985, declining to approximately 43,700 t·year-1 in the early-2000s and finally spiking to about 65,300 t·year-1 by the late-2000s. These catches coincide with a severe depletion of fish stocks, especially those of bentho-demersal species, due in part to fishing overcapacity in the artisanal sector, despite attempts to limit effort by the government. Only starting in 2006 were catches reported in national statistics and from 2006 to 2010 reconstructed catch was seven times the reported catch. Nearly 70% of this catch was from the recreational fishing sector, due in part to technological advancements and increased investments in the construction and improvement of secondary ports.
