Resumo: | The present study was carried out in samples of Ostrea columbiensis (Hanley) taken from the estero ”Las Alforjas”, during de period between march-december of 1989. Three stations were selected in the estero, in order to observe the fixation, growth and survival of the larvae in special collectors designed by the authors. The percentage of fixation in the station 1 was 25,8%, in the station 2, 37,8% and in the station 3, 36,4%. The larvae oyster got fixed, preferably, by the external face of the collector (big valve) in a percentage of 64,3, while on the external face this percentage was 35,7%. The average height of the oysters during the whole period of study was 52 mm, with a monthly increment of 5,2 mm. The percentage of the oysters survival was 84,4%. During the period of study, the average reading for pH, temperature, oxigen, and salinity were 7,3,26,12,4,5 ppm and 32,1 ppt, respectively.
