DISTRIBUSI DAN KEPADATAN PLANKTON DI PERAIRAN TELUK AMBON
ABSTRACT: This research is
done started from April until July 2007 in Ambon Bay at 17 station which is representative
sample of inner and outer bay. Sampling used by net of plankton KITAHARA (phytoplankton)
and NORPAC (zooplankton). Result of the research showed that the distribution
of plankton is concentrated in inner bay in which indication from height in
average of plankton density. Highest of phytoplankton density is 24x106 cell/m3
occurred on May, and the highest of zooplankton density occurred on August
about 9520 ind./m3. Predominance plankton in Ambon Bay are Chaetoceros, Thallasionema,
Nitzchia, Rhizosolenia, Thalassiosira, Trichodesmium for phytoplankton, and
Copepod, Chaetognath, Lucifer, Thaliacea/Larvacea for zooplankton, and
Meroplankton. The highest percentage of plankton reach about 63.47%
(Thalassiosira) and 62.27% (Copepod). Blooming of red tide from non toxic phytoplankton
occured on April by Thalassiosira and Trichodesmium, but it is not caused
