F.M.Ghazzawi (1939) Plankton of the Egyptian waters. A study of the Suez Canal Plankton. Notes and Memories of the Hydrobiology and Fisheries Directorate of Egypt, No 24. (A) The Phytoplankton. Preliminary Report

Study Extent

Six stations were examined: S.C.1 - Western Jetty at mouth of the Canal S.C.2 - Ballah signal station S.C.3 - 1km S.W. of the Canal Company’s landing stage at Ismailia S.C.4 - Northern Light buoy in Great Bitter Lake S.C.5 - Kilometre 130 of the Canal in Little Bitter Lake S.C.6 - Last buoy but one of the Western side of the Canal at Port Tewfik

Sampling

Hauls were taken with the international horizontal tow-nets; the fine net has 200 and the coarse 60 strands per inch. The length of the bolting silk is 2 meters and the mouth of the net is 50cm in diameter. Two small motor boats were used; “EL-HILAL” and “EI - ZAFIR”.

Method steps

1. The catches; as soon as they were brought up to the boats were treated with 4% formalin (40% commercial formalin diluted with sea water to 4%). The nets after each catch were washed thoroughly first is sea water and then in fresh water and allowed to dry in the shade by hanging in the air, as direct sunlight had a detrimental effect upon the life of nets. Hydrographical observations were recorded at every station. The Temperature and PH were also recorded.
