Sažetak
Temporal fluctuations of species composition and abundance of fish larvae in the Kornati archipelago and Murter Sea were studied over 12 months from january to December 1990 from seven stations. A total of 2145 larvae, representing 28 families and 52 species, were collected using two types of plankton nezs on each station, "Helgoland" and "Bongo". The community was dominated numerically by a few species: Sardina pilchardus (29, 2%), Engraulis encrasicolus (28.7%), Serranus hepatus (7.5%), Sarpa salpa (5.2%) and Cepola rubescens (4.7%, constituting 75.35 of the total catch. Similarity between patterns in the abundance of the 11 most common specie swere examined using correlation matrix-based principal component analysis. Results were compared to the abiotic factors leading conclusion that only a low amount of variation in the abundance field can explained by temperature and salinity.
