Brojnosti rodova Synechococcus i Prochlorococcus određene su na dvadeset i jednoj postaji smještenoj na području priobalnog mora srednjeg i južnog Jadrana te na tri postaje smještene na području pučinskog mora srednjeg Jadrana. Brojnost roda Synechococcus iznosila je u rasponu od 102 do 105 st mL-1 na priobalnom području, te od 103 do 104 st mL-1 na području pučinskog mora. Brojnost roda Prochlorococcus iznosila je u rasponu od 0 to 104 st mL-1 na priobalnom području, te od 103 do 104 st mL-1 na području pučinskog mora. Sezonska raspodjela brojnosti navedenih rodova uglavnom je pokazala porast vrijednosti u toplijem te smanjenje vrijednosti u hladnijem razdoblju. Najviša brojnost Synechococcusa utvrđena je u Kaštelanskom zaljevu i iznosila je 4.6 105 st mL-1,dok je najviša vrijednost Prochlorococcusa utvrđena na području Šibenika te je iznosila 7.1 x 104 st mL-1. Rezultati istraživanja pokazali su uglavnom prevladavanje brojnosti roda Synechococcus nad brojnostima roda Prochlorococcus. Temperatura je imala veći utjecaj na promjene brojnosti roda Synechococcus u odnosu na raspoložive koncentracije hranjivih soli. Rod Prochlorococcus bio je pod većim utjecajem raspoloživih koncentracija hranjivih soli i gibanja vodenih masa u odnosu na utjecaj HNF-a.

Synechococcus abundance ranged from 102 to 105 cells mL-1 in the coastal area, and from 103 to 104 cells mL-1 in the open sea Prochlorococcus abundance in the coastal area ranged from 0 to 104 cells mL-1, and from 103 to 10 4 cells mL-1 in the open sea. The seasonal distribution of Synechococcus and Prochlorococcus mostly showed an increase in abundance during the warmer period and a decrease during winter. The highest abundance of Synechococcus was found in Kaštela Bay with values at 4.6 x 10 5 cells mL-1, while the highest abundance of Prochlo-rococcus was determined in the Šibenik area and recorded as 7.1 x 104 cells mL-1 Synechococcus was found to be more abundant than Prochlorococcus in most cases. The abundance of Synechococ-cus was influenced more by temperature than nutrient availability. The abundance of Prochlorococ-cocus was influenced by nutrient availability and the movement of water masses more than by HNF.
