Abstract :
AbstractCase sampling was performed in the winter of 2020 in the eastern region of Gorgan Bay in three coastal and central regions to investigate the causes of bird death. For this purpose, algal (macro and micro), zooplankton and water communities were sampled. The results showed that a total of 44 species of phytoplankton were identified. 4 species equal to 12.5% and Euglenophyta branch with the lowest number with 2 species equal to 7.7% of the total species. The highest mortality was observed in Changar species and a few flamingos were observed. No algal blooms were observed during sampling. The density of cyanophytes was the lowest. Therefore, the cause of death of birds cannot be density or planktonic secretions.
