عنوان المقالة:دراسة غزارة العوالق الحيوانية في المياه الساحلية لمنطقة برج اسلام Study the abundance of zooplankton in the coastal waters of the Burj Islam
We present in this research the most important results related to the total abundance as well
as the abundance of various groups of zooplankton in the coastal area of Burj Islam and its
vertical changes up to 300m depth, during the research period extended between
November 2011 to June 2019, and the sampling process was associated with the
measurement of temperature and salinity.
The results of the study showed significant temporal and spatial changes in the abundance
of various groups of zooplankton in the studied area, where the total abundance of
zooplankton ranged between 20 and 597 ind./m3, which is low abundance compared to
other regions of the Syrian coast and the Mediterranean. Copepoda was in the first level in
terms of its contribution to the total abundance of zooplankton and ranged between 61% to
98%, the mean of relative abundance of the other groups did not exceed 3.7% recorded by
the group of Appendiculata, Hydrozoa, Thaliacea, Chaetognatha, Ostracoda, with mean of
relative abundance 2.77 and 1.9 and 1.8 and 1.6%, respectively, and the mean of relative
abundance for the remaining groups did not exceed 0.4%. In general, we have noticed a
sharp decrease in the abundance of the various studied zooplankton groups, especially
under the depth of 100 m, which is consistent with many studies that have taken place in
the coastal waters of the Mediterranean. We have also noticed a great correlation for the
abundance between Copepoda and a number of groups of zooplankton, which are:
Appendiculata, Chaetognatha, Hydrozoa, Ostracoda and Thaliacea, where the value of (r)
0.9 and 0.83 0.82, 0.77, and 0.65, respectively.
