Latest version published by Hellenic Center for Marine Research on Feb 7, 2018 Hellenic Center for Marine Research

A study of the plankton in the Suez Canal could throw some light from the explanatory point of view, on the distribution of the planktonic forms of the two different water bodies of the Mediterranean and Red Sea. From the fisheries point of view, the plankton study is indispensable to seek out the relation between the abundance and movement of fishes and the fluctuations in the plankton; both in quantity and quality at different times, places and depths.

Sampling Methods

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".

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

Method step description:

  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.
