H.Bachmann (1936) The fishery grounds near Alexandria. XIV. Phytoplankton from the Nile. Fisheries Research Directorate of Egypt, Notes and Memoirs No 22

Egyptian plankton samples for revision as to its phytoplankton content. First samples are dated in 1933 owned by Prof. Steuer, while the other samples are from the Nile area and collected by Dr. Hans Amberg, in 1904. The samples that come from the large district of the Nile prove that the Melosira in Prof. Steuer's material represents a real phytoplankton component of Nile water and not merely a passive swimming organism. Study Extent: Phytoplankton from the Nile area Quality Control: Taxonomic quality control through WoRMS Method step description:

Apart from the samples of 1933, there are samples of Nile owned by H. Bachmann and collected by Dr Hans Amberg, in 1904. The equipment used is a very small net. The samples are from the following stations: (1) Assuan, 1904/02/09; (2) Above Edfu, 1904/02/08; (3) Dendera, 1904/02/04; (4) Assiut, 1904/02/02; (5) Above Fashn, 1904/01/30; (6) Cairo, 1904/04/08 and (7) Bedreshein, 1904/01/29. The samples 1,2,3 contain the genus Melosira and were very frequently. The samples 4,6 and 7 conatin Melosira granulata var. augustissima and the typical Melosira crucipunctata. These samples showed hardly any other phytoplankton. One may mention: Pediastrum clathratum, with varieties, Surirella splendida, Eudorina elegans.
