Summary A total of 644 juvenile gilt sardine, Sardinella aurita Valenciennes 1847, were obtained by random sampling from the Zrmanja River estuary (Novigrad Sea Bay, eastern part of the North Adriatic), which is a nursery ground for small pelagic fish species. Gilt sardine were caught by purse seine as well as with beach seine. From their first recorded occurrence in this area, representative samples were collected monthly from October 2000 to May 2001. Monthly fluctuations in length frequency distributions of gilt sardine juveniles were observed. Total length was in the range of 8.0–16.0 cm. Minimum and maximum weights recorded were 3.02 g and 28.98 g respectively. The modal number of vertebrae was 47, with a mean of 47.13 vertebrae. Length–weight relationship of the gilt sardine juveniles was described by the expression: W = 0.0043 L 3.1162 .
