ABSTRACT
Statistical data on the Sardine gill net fishery during
the period 1963-1976 was discussed. Also, the monthly
fluctuation in the landings of Sardine gill net from ElMax region was analysed during the same period (1963-1976),
before and after Asswan High Dam construction.
The catch-per-trip as index of fish abundance at ElMax region was estimated for the different months during
1977, tha t showed increased fi sh abundance in the SUlllller
months. The species compos i tion.. as well as the length
frequency and age composition of the gi 11 net catch was
studied.
The survival and mortality rates are deduced for both
Sardinella aurita and S. maderensis.
