Sažetak
The minimal length at first maturity, as well as L50 and L100 of anchovy, Engraulis encrasicolus (L.), were estimated. length frequency and gonad data (ripe, spawning, spent, with semi hydrated and hydrated oocytes) of 2 530 anchovy specimens were analsed during the peak of anchovy spawning period - in July and in August 1990 and in May 2003. Anchovy specimens were caught by purse seine in the Zrmanja River estuary, which is a nursery ground of the small pelagic fish species. Total length of anchovy specimens used for obtaining the lowest size of its sexual maturation ranged from 4.4 to 12.5 cm and weight range from 0.4 to 13.8 g. The minimal length at first maturity of these fish species was 8.2 cm of total length (male), L50 was 9.0 cm and L100 was 11.5 cm. Highly significant correlation was found (r2=0.9537 ; SE=0.0019).
