S8q)le. of Merlucct.. _rLuect.. .cttterrlll’leW L. from
the Egyptlln Mediterranean water. were .tudled and compared
for the yelr. 1961, 1972 Ind 1992. The length-weight

dlff.renc. at the 95 X prob. Level between the
w.lght.lt-Length dlta of the three sampled perl ode, whIle
the condItIon factor estimates proved that the value of 1972
perfod WI’ lower than the others. This was Ittributed to the
