Sažetak
Anchovy Engraulis encrasicolus L. 1758, is one of the most abundant species in Croatian fisheries. However, in the last few years, landings of this commercially very significant species have decreased from 14 163 tons in 2011 to 8904 tons in 2013. Therefore, the aim of this study was to analyse current state of anchovy population in the Eastern Adriatic Sea. In total, 612 anchovy specimens were sampled from June to December 2014. All fishes were sampled from purse seine landings, i.e. from fisheries zones (B, C, E and F) of the Eastern Adriatic Sea. Total length (LT) varied from 10.0 to 16.6 cm, the average length was 13.5 ± 0.99 cm, and modal length class was 13.0 cm. Number of male specimens exceeded the number of female specimens (m/f=1.63). Analyses of length-weight relation indicated positive allometric growth (b=3.469 ; r2=0.899). Condition coefficient (K) ranged from 0.52 to 0.69. In general, condition values were higher in longer fishes. In the beginning of this study, in June, anchovy was spawning, and inactive phase of maturity cycle started after September.
