ABSTRACT
Age and growth of the grouper, Eplnephelus chlorostlg11l1.
fr,,, the Red Sea were studied. Scales froRi 433 fish were
USN to estl_te the age and growth rate of this species.
constants of the length – weight relationship were
camputed using the least square and geometric regression
..~. The length – wefght equatfons computed were:
w 1.7620403 X 102 L2.8933592
by the least sqllare method and
w 1.488702 X 102 L2.9399814
by the geometric regression method. The Von Bertalanffy
growt~ in length equation was as follows:
lt 113.7934 [ 1 _ .-0.0728 ( t + 1.0804) ].
