Abstract
Atotal of 837 Lutjanus limolatits was collected monthly from Bitter Lakes during October 2002 through October 2003 to study age and growth, mortality, relative yield per recruit and relative biomass per recruit Age was determined from otolith's reading and the results showed that the maximum life span of L. iineolaius is 3 years. The growth parameters were estimated as K = 0.60 year-1, Loo = 22.92 cm TL and to = -0.27 yr. The annual rates of total, natural, fishing mortality and exploitation rate were calculated as 2,5, 0.6, 1.9 and 0.76 year-1 respectively. The high level of both fishing mortality and exploitation rate indicated the high level of exploitation of this species. The length at first capture Lc was 31.1 cm TL.The relative yield per recruit analysis showed that the stock of L. lineolatus is over-fished. To maintain this valuable fish resource, the present fishing effort
