INTRODUCTION
Light and purse-seine fisheries started in the Egyptian Red sea regions in
1960. The fisheries authorities have been afraid of over-exploitation since
the start of the fisheries. They decided to increase the number of fishing boats
J gradually and recording catches to -estimate the effort associated with the
optimum yield. Five aLd four motor boats were permitted in the Gulf of Suez
and Ghardaqa regions in 1960 and 19,16 respectively. The boats were increased
in the Gulf to ten in 1961, 1962; and to fifteen since 1963 while fishing has been
prevented in September and October each year. That is, fishing effort was
increased to about 1.25 timeS with respect to 1961-1962 period assuming equal
catchability all ~hp year round. h was decided that this last effort would provide
the optimum yield.
This work was prepaired to present some studies that may help the proper
exploitation of abundant sardines, viz. Sardinella jmsieu (Lacepede) and Sardinella sirm (Valbaum). S. jmsieu formed about 80% of the Gulf catcb; the
two species about 80% of Foul Bay catch, and about 25% of Ghardaqa Catch.
