Results from brown shrimp (Farfantepenaeus aztecus) abundance evaluation of the coasts of Tamaulipas during summer of 2002 are presented. Four exploratory fishing cruises were carried out in the coasts Tamaulipas during August, where biomass values were analyzed by swept area. These values were compared with data of previous exploratory fishing cruises. The information was complemented with data of size structure, observed during May in Laguna Madre and information from a survey carried out in June 2001. The results shown that the yield of capture and biomass existing are smaller than the previous months. Likewise, the structure of sizes in the inshore system, from the coast and the distant zone to the coast (20 m to 42 m depth) shown a delay in the recruitment and abundance on decrease, possibly explained as a result of a temperature and rainfall abnormality. The low values observed of biomass and sizes, caused that yields in the commercial captures of open sea were smaller than the expected ones.
