Sažetak
The Vrgorac goby Knipowitschia croatica Mrakovčić et al. 1994) is a critically endangered freshwater goby species that is endemic to the karstic Matica River of Croatia (Mrakovčić et al. 2006). The genus Knipowitschia, a member of the sand goby group, is characterised by a short life span which rarely exceeds two years. This study gives the first description of the otolith morphology of the Vrgorac goby. Age structure and growth were calculated separately for males and females, and pooled as the population, to determine the growth model. The high growth coefficient K obtained in both males and females is owing to the short life span of this species. Age readings from otoliths show that both males and females achieve almost maximum body lengths at sexual maturity in their first year of life.
