Chaetognaths in Boka Kotorska Bay

Temporal and spatial distribution of pelagic chaetognaths was studied at six stations in Boka Kotorska Bay from March 2009 to June 2010. This work present for the first time detailed information of the ecology of chaethognats in the specific ecosystem of Boka Kotorska Bay. Chaethognats were more numerous in Kotor Bay and Parasagitta setosa was dominant species at all stations. Salinity was the main hydrological factor which influence on chaethognazh abundance. Small copepods and copepodites were the main food for the most abundant chaethognath species as for juvenile stages. Low population densities were noticed during ctenophore Bolinopsis vitrea bloom in 2009 indicating their important nutritional competition relationship.
