Abstract

Brazilian sardine datawere collected between September 1981 and August 1982 from the southeastern Brazilian waters. Otoliths were read using reflected ligth on the surface of the whole structure. Three methods were used to determine the time of ring formation, being the mean length per ring the best one. There are two annual rings clearly visible, one laid down in November/December, and the other one laid down in March/April. A method of age determination is described, being the maximum age 3 years.
