Resumo

We determined the age of the commercial marine fish pescada-foguete (Macrodon ancylodon, Bloch 1801) caught by trawls along the southern coast of Brazil (28oS-34oS), from 1961 to 1963, by means of the annuli in otoliths (CHUGUNOVA, 1959). We correlated the mean total length (L) in centimetres with the age (t) in years by means of the BERTALANFFY expression adjusted by FORD-WALFORD method (BEVERTON & HOLT, 1957). The mean total length was correlated with the mean weight (W) in grams, by means of the expression W = aLb adjusted by least square method, after a logarithmic transformation. Results:
