ResumenThe fishery of the red shrimp Aristeus antennatus is one of the main fisheries in the western Mediterranean. In this work we evaluated the status of the A. antennatus fishery in the Catalan region (NE Spain) in recent years, 2008-2010, and compared it with the last historical available data, 1984-1989. Fishing mortality and population biomass displayed high inter-annual variability. Population biomass values were higher for the recent period. Yield per recruit analysis showed a general overfishing pattern, for both periods. In general inter-annual variability of estimates suggested the existence of non-fishery effects affecting the population dynamics of this species in the area
