Abstract
This study deals with age determination of the striped mullet Mugil cephalus collected from Bardawil Lagoon during four successive fishing seasons (1995 to 1998). The scale reading and length frequency analysis show that the catch of M cephalus consists of 6 year classes. Age groups I and II represent the bulk of the catch. The growth parameters were determined from both length frequency and length-at-age data. The estimated parameters based on length -at-age data were
U = 74,164 cm., K= 0.246 Y"1 and t0 = -0.969 The similarity of the estimated growth parameters is reflected in the small range of the growth performance index (q>), which indicates the compatibility of the two methods for the assessment of this species. The length weight relationship was calculated for each season separately and the mean resultant formula was W= 0.01547
