Sažetak
A total of 644 juvenile gilt sardine, Sardinella aurita Valenciennes, 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. Mainly representative samples were collected monthly, from their first recorded occurrence in this area from October 2000 to May 2001. Monthly fluctuations in length frequency distributions of gilt sardine juveniles were observed. Total length was in the range from 8.0 to 16.0 cm. Minimum and maximum weights recorded were 3.02 g and 28.98 g respectively. Modal number of vertebrae was 47 and their mean was 47.13 vertebrae. Length-weight relationship of the gilt sardine juveniles was described by the expression: .
