ABSTRACT
The regression coefficient “b” in the fonnull
w- el b for lutjenus Hneolltus collected from Ahka,
near Suez was found to be 2.8852. This value was
statistically anillysed an~ the fish showed isometric
growth. The relative condition factor It different
lengths distinctly decreased at the end of the first,
second, thrid end fourt~ years of life for both
sexes. Fecundity was f1uc~uated between 4873 – 27644
ripening eggs for the range of total length 107
– 177 nn. It was found that the absolute fecundity
is the better expression than the relative one.
The fecundity length relationship lollS found to be
more correlated where it 15 best described by the
equation:
Log F- -2.742 + 3.2J4 Log L (r- 0.984).
