The shrimp Pleoticus muelleri is the most important species in the crustacean fishery off Patagonian Argentine Sea. Morphometric and reproductive aspects of 1,564 specimens from Rawson Port zone, South Argentine, were analyzed. The shrimps were taken approximately 12 nm by the trawling coastal fleet, between January and April 2001. From the total sample, only 3.9% were juveniles. Mature and impregnated females were mostly found in January (86.27%) and the lowest peak was in March. Immature female shrimps were caught in only in April. These results show the importance to characterize the shrimps from landing samples, to the fishery management.
