Study Extent

This dataset is based on a faunistic report compiled from the expedition by the Fisheries Research Directorate in fishery grounds near Alexandria at 1933.

Sampling

This dataset is only a part from a large expedition 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. For plankton samples, vertical hauls were made using medium sized nets with buckets of celluloids with gauze bottom. 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. Taxonomic identification of mollusc species was made by J.R. Le B. Tomlin, G.H. Crawford and S. Jaeckel.

Mollusc species were found in about 150 benthic stations in the coasts of Alexandria, Egypt. Some species with pelagic larvae were also found in planktonic stations.
