Abstract

Gelatinous zooplankton (GZ) is a group of zooplankton that consists of various organisms which have a vital role in marine ecosystems. This study aims to investigate the abundance and biovolume of GZ, especially during the northwest monsoon season (February and March) in the inner part of Ambon Bay. Zooplankton samples were obtained using a plankton net, towed vertically. Influences of environmental drivers on abundances and biovolumes were analyzed using the principal component analysis (PCA) loading plot. Approximately 16 genera of zooplankton were found in the inner waters of Ambon Bay, of which Thalia sp. was the dominant genus that occurred with highest abundances and biovolume. The range of GZ abundance and biovolume were 0.71 to 106.86 ind m-3 and 0.05 to 1262.35 mm3 m-3, respectively. Nutrients were found as the driver that governed the GZ community in Ambon Bay waters.
