|Abstract:||The objective of the present paper was to estimate the catch rate of Green tiger shrimp (P. semisulcatus) from Bushehr coastal water with some statistical uncertainty methods. Collection of data was performed during 94 hauls by C/V SHANAK. Fishing took place at three depths strata (stratum A: <10m depth, stratum B: 10-20m and stratum C: >20m). The non-parametric bootstrap method was utilized to estimate the catch rate (±Confidence interval) (kg. h-1) of P. semisulcatus for each stratum. A randomization test was also used to compare the mean catch rate among three depth strata. The minimum and maximum catch rates (kg. h-1) of P.semisulcatus was obtained between 4 - 8.8 for depth A, 6.8 – 8 for depth B and 2.7 – 5.1 for depth C (α=0.05). Results of the randomization test showed that there is no significance difference among the mean catch rate in three depth strata in Bushehr coastal water (P>0.05). Managing fisheries under uncertainty has become a top priority for fishery biologists around the world, and this paper is the first study on utilization of uncertainty in fisheries researches of the Iranian water of the Persian Gulf.|
