Sažetak
Temporal fluctuations of species composition and abundance of fish juveniles in the National Park Kornati were studied over 12 months from January to December 1992. A total of 40168 individuals, representing 24 families and 69 species, were collected using a 50 m long beach seine. The community was domintaed numerically by a few species: Atherina hepsetus (45.90%), Sarpa salpa (21.21%), Diplodus vulgrais (10.49%), and Symphodus ocellatus (6.98%), constituting over 84.58% of the total catch. similarity between patterns in the abundance of the 17 most common species were examined using correlation matrix-based principal component analysis. results were compared to the abiotic factors leading to the conclusion that only a low amount of variation on the abundance field can be explained by temperature, salinity and dissolved oxygen.
