Billards A. 1936.The fishery grounds near Alexandria. VI Hydroidea. Notes et memoires No 13

This is a historical dataset that was published in 1936 by A. Billards and concerns of the faunistic report on the Hydroidea collected during the floristical and faunistical survey of Adolf Steuer on the coasts near Alexandria mainly with the vessel “El Hoot”. This dataset covers the time span of 2/9/1933 to 12/11/1933 and contains occurrence data of Hydroidea in the coasts of Alexandria, Egypt. The digitization of this dataset was done by LifewatchGreece team.

Hydroidea were found in about 20 sampling stations near Alexandria, Egypt, eastern Mediterranean.

This dataset is only a part from a large faunistical expedition(http://ipt.medobis.eu/resource?r=egyptexpeditionpreliminaryrepor) that took place in the coasts near Alexandria. The samples were collected by A. Steuer. For bottom samples almost exclusively a dredge with 20x70 cm opening was used. A single catch was made in a depth of 20 m with a large otter trawl in the eastern part of the Bay of Abukir. In general, the motor-launch of the Marine Laboratory "El Hoot" was used for dredging and a rowing boat in shallow water. All excursions were one-day trips. After the expedition, taxonomic identification of the samples was done by specialists. The results of this expedition were published in separate for each taxonomic group volumes. Thus, sampling methods were described in a preliminary report by A. Steuer. Species indentification and description were done by A. Billards.
