Abstract
An estimate of the age and growth of Rhabdosargus hqffara collected from the Suez Bay is made by examining the growth increment of their scales. The growth rings showed that R. hqffara rarely attain more than four years. The Bertalanffy growth parameters were estimated as K= 0.47 , L^ = 26.79cm and to = -0.36 . The mean total mortality coefficient HZM estimated by two different methods was found to be 1.19 .Natural mortality coefficient "M" was estimated to be 0.29. Exploitation rate "E" was computed as 0.76. The yield per recruit was estimated using the model of Beverton and Holt (1957). The results indicatid that the stock of R~ haffara in the Suez Bay was overexploited and the fishing mortality coefficient must be reduced by about 40 % to obtain the maximum yield per recruit.
