Crustacean Zooplankton Was Studied In Five ponds In AL- Sinn's
Fish farm. As a one Of The Most Important components Fresh
Water Ecosystem . The samples of zooplankton were collected
During Period From November 2013 To March 2015, By One
Sampling a Month.
The study included 132 Free – living fish in Lake of 16 Tishreen Dam,
collected randomly during the period from 22/11/2011 until 22/10/2012, on
average once a month, for detecting the infection of parasitic copepoda, and
determine the distribution rate, and their effect on the fish productivity.
Vertical sampling process took place to Copepoda during the summer and winter of
2009 and 2010 from Alzzouzo castle which is located in the coastal region of Jableh city.
This region has special environmental properties. Sampling was accompanied wi
th
measuring water temperature, salinity, and dissolved oxygen in the water.
The total number of samples studied in all areas of study is 106 samples. 100 species
were identified during the summer, while 89 species were identified during the winter;
most species belongs to the order of Calanoida. It was noted by the study that most species
appeared in two seasons together, while some species appeared in the season without the
other. It was also noted that the abundance of Copepoda was higher in summer with an
average of (5314 individual / m
3), while the average in winter was (4353, 40 individual / m
3).
It was clear from the study that the station near the beach was less diverse and more
prolific than the offshore station during the summer and winter together.
