Abstract

 

The length-weight relationships (LWR) and relative condition factor were calculated for five marine fish species collected by shrimp trawls from Iranian waters of the Persian Gulf. Sampling was carried out with bottom trawl net (with 40 and 50 mm mesh size (stretched length) in the cod-end and panel) during June to August 2011. Trawling took place at depths ranging from 7 to 30 m. The values of the exponent b varied between 2.7300 (Sillago sihama) and 3.0156 (Netuma thalassinus). Relative condition factor (Krel) did not differ significantly (analysis of variance (ANOVA) test, P > 0.05) and ranged from 0.98 ± 0.14 (Pelates quadrilineatus) to 1.03 ± 0.17 (N.  thalassinus).

 

Key words: Length-weight relationship, marine fish, condition factor, Persian Gulf.
