The abnormalies from different larval stage of Litopenaeus vannamei that grow up from hatcheries were detected. The survivor rate and the physicochemical variables that characterized the water quality were calculated. Five hatcheries rooms were used, with ten concrete tanks each one, and 13 different abnormities between Naupli to Postlarval stage were detected, with a frequency form 0 to 69 %, accordingly to the sub-stage. The abnormities associated with the larvae mortalities are absence of caudal processes in Naupli and Zoea, abnormal uropods development in Zoea III, curved body in Zoea III and Mysis, and pleopods absence in Postlarvae. There are different abnormally incidence accordingly from the laboratory origin of the Nauplii. So high nutrients and ammonium values were found to characterized the water quality in the zone near the hatcheries, and was bound the parameters responsible for the abnormally at the different larval stage.
