Current study focuses on the population dynamic and pattern of the giant red shrimp A. foliacea as the third part of series on commercial crustaceans in the study area. Uniand multi variate analysis on the spatio-temporal distributions of the density, biomass, reproduction pattern, age and growth parameters, mortality and the exploitation status of the stock of the species distributed in the area were evaluated. The highest average value of BI (79.9 kg km-2) and DTOT (5105 n km-2), were estimated from the 500 m stratum. Mature individuals distributed in deeper than 400 m, and the recruits were available between 400-699 m depth. The gonadosomatic index of A. foliacea females showed a sharp increase between May and August, and the first maturation size (FMS) was estimated ≈ 39 mm (1.8 age). Examining the general pattern of the frequency distributions revealed maximum 3-year modes for males while females displayed 5year modes. Since current level of fishing mortality (Fcur=0.848 year-1) is higher than reference point (F0.1=0.540 year−1) and too close to Fmax (=0.960 year-1), the stock of A. foliacea females had a potential for the growth overfishing.
