MORPHOLOGICAL CHANGES OF FISH SPERM AFFECTED BY COPPER USING (SEM)

This study was carried out from April 1999 to March 1999. During this study 55 genus of phytoplankton were seen including: diatoms (Bacillariophyceae), dinoflagellates (Dinophyceae) and blue green algae (Cynaophyceae). The most population was seen in diatoms (25583 cells/lit), dinoflagellates (687 cells/lit) and blue green algae (75 cells/lit), respectively. The highest record of diatoms was seen in winter (66922 cells/lit), but blue green algae were dominated in summer (157 cells/lit). The highest population of phytoplankton was seen in during June in surface water of eastern creek (156660 cells/lit). In statistical study, difference between stations of two branches of creek (east branch and west branch) wasn't significant
