The aim of this study was to observe phytoplankton species and associated bacterial populations in the coastal waters of the United Arab Emirates (UAE). Samples were collected from the Umm al Quwain (UAQ) and the Dibba coastal water area. The samples were analyzed to determine the phytoplankton species and associated bacterial populations. A Fluorescent in situ hybridization (FISH) technique, using six sub-groups and a family-specific oligonucleotide probe, was performed on the ethanol and paraformaldehyde fixed samples. The microscopebased analysis of eight samples revealed the presence of both toxic and non-toxic phytoplankton species. The four dominant harmful dinoflagellate species detected in the samples were Cochlodinium polykrikoides, Dinophysis caudata, Prorocentrum arenarium and Protoperidinium spp. The FISH analysis showed a diverse bacterial community associated with the phytoplankton species. The overall findings of this study showed the presence of 4 non-toxic and 11 toxic phytoplankton species in the UAE coastal water samples. The FISH analysis indicated the presence of a highly diverse bacterial community belonging to five different sub-groups (Alpha, Beta and Gamma sub-classes of proteobacteria, High and Low G+C sub-groups) and one family (Enterobacteriaceae).
