Horse mackerel, Trachurus murphyi, were collected during the fishing seasons of 1962–1963 and 1963–1964 from three different fishing areas off the coast of Chile. Age and growth were studied through the otoliths and length frequency distribution of the fish. More than 90% of the captures consisted of 4‐ to 6‐year‐old fish. The oldest specimen, measuring 63.5 cm and weighing 2,400 grams, was 10 years old. The major growth occurred during the first year of life.
