Fig. 2. Frequency distribution of estimated hatch dates of early and late larvae, juveniles and pre-recruits of Sardinops sagax spawned in 2004 (top) and 2006 (bottom). The hatch dates in a month were assigned to early, middle and late month in 10 or 11 days intervals. Thick bars indicate survey period for early larvae in 2004 and late larvae in 2006. Shaded area represent period of the late spring for the growth-selective analysis.
