Population dynamics of Green Tiger Shrimp (Penaeus semisulcatus) in the Persian Gulf (Bushehr Waters)

Abstract

The population dynamics of Penaeus semisulcatus was studied out in the Persian (Bushehr province waters) through a series of research cruises conducted by the R/V Lavar. The growth and mortality parameters for both sexes were estimated by FLEFAN and FISAT computer programs. The following results obtained for males: L∞=37mm, K=1.8per year, t0=0.3, M=2.8, F=4.5 and Z = 7.3. These results for females were as follows: L∞=49 mm, K = 2.6 per year, t0=0.6, M=3.2, F=6.7, Z=9.9. According to obtained results, the exploitation rate for males and females were 0.61 and 0.67, respectively and the ϕ-value was estimated 7.8 for males and 8.3 for female. The sex ratio Was M:F-1:1 and the spawning season was from January to March with the main peak in January. The maximum age for males and females were determined 21 and 19 months respectively.
