| Abstract | ||
| Stock of Pseudorhombuss arsius in north-west Arabian Gulf was studied from March 2004 to July 2005. A total of 6772 specimens of P. arsius were collected, their lengths ranged from 8 to 33cm. Length-weight relationship was obtained as W = 0.0271 L 3.0011. Relative condition factor ranged from 0.97 in June to 1.05 in March. The fish stock was assessed using FiSAT program. Growth and mortality parameters estimated were: L∞= 40.1 cm, K= 0.59, Z= 2.3, M= 1.2 and F= 1.1. Current exploitation rate (0.48) of P. arsius was slightly lower than the optimum level. A bimodal recruitment pattern of unequal strength was observed. Maximum yield per recruitment could achieved at Emax= 0.52. | ||
