The equation log W=a+bL (where W=dry weight in ug, and L=total length in mm) was used to describe the growth in weight of larval anchovy collected in two areas of the Argentine sea, sampled in different months and several years. Regression lines were compared by covariance analysis applied to two size groups, namely larvae less and over 10 mm total length, as an evident break in the slopes indicated the existence of a change of rhythm in the trajectory of larval growth in length. Significant differences between the slopes of the growth lines were observed within the smaller size group. No regional or yearly differences could be established fo larvae larger than 10 mm.
