Monthly samplings were carried out during August, 2005 to November, 2006 to analizing the changes of the abundance of commercial juvenile penaeid shrimps in the North part of Laguna Madre, Tamaulipas. In every nine points a night trawl were carried out using a seine net of mesh size of 1.25 cm and 6 m length of bottom rope. Three commercial penaeid shrimp species were found and each one presented high abundance values for different periods of the year. Brown shrimp, Farfantepenaeus aztecus, in April-May period; pink shrimp, Farfantepenaeus dourarum, in December-January, and the white shrimp, Litopenaeus setiferus in July and September. These results showed that different species presented a differential temporal use in Laguna Madre.
