Abstract:
This study aims to determine the abundance and composition of zooplankton in the waters of Doreri Bay. Water samples were taken at a depth of 5 meters and 10 meters at 2 research stations. Identification of zooplankton was carried out using the sweep method. The results obtained that the average abundance of zooplankton at station 1 at a depth of 5 and 10 meters respectively was 54 ind/L in the morning and 33 ind/L in the afternoon and 33 ind/L in the morning and 30 ind/L in the afternoon. On the other hand, the average abundance of zooplankton at station 2 at a depth of 5 meters and 10
meters consecutively was 61 ind/L in the morning and 67 ind/L in the afternoon and 81 ind/L in the morning and 66 ind/L in the afternoon. The number of zooplankton genera is 29 genera with a percentage of 32.41% in 1 genera (Nauplius sp.), 20.99% in 1 genera (Calanus sp.), 5-9% in 2 genera (Epiplocylis sp., and Euntintinnus sp.), 3-.5% in 3 genera (Arcelia sp., Rhabdonella sp., and Salpingella sp.), and 0-3% in 22 genera (Abarenicola sp., Amphorellopsis sp., Ascomorpha sp., Balanus sp., Codonellopsis sp., Cornutella sp., Cyphoderia sp., Evadne sp., Lecane sp., Lithotrobus sp., Notholca sp., Oikopleura sp., Paravafella sp., Penaeus sp., Pinctada sp., Pleuraspis sp., Protorhabdonella sp., Spiophanes sp., Tintinnidium sp., Tintinnopsis sp.,Trichocerca sp., and Undella sp.).
