Polybrominated diphenyl ethers (PBDEs) were measured in three species of fish (yellowfin seabream [ Acanthopagrus latus , a predatory fish]; Klunzinger’s mullet [ Liza klunzingeri , a pelagic fish]; and large-scaled tonguesole [ Cynoglossus arel , a demersal fish]) collected from two sites in the northwestern part of the Arabian Gulf, a marginal sea of the tropical Indo-Pacific Ocean. Concentrations of ΣPBDEs ranged from 11 to 57 ng g −1 lipid weight (lw) for mullet, 5.0–38 ng g −1 lw for tonguesole, and 2.8–48 ng g −1 lw for seabream in Kuwait Bay, whereas in the open gulf, concentrations ranged from 6.0 to 160 lw for mullet, 8.3–190 lw for tonguesole, and 7.1–62 for lw for seabream. The congener composition in all species from both sites was dominated by BDEs 47, 99, and 100, which together constituted approximately 90% of the congeners detected. Although no statistically significant intersite differences were found, ΣPBDEs concentrations in mullet were significantly higher than those in seabream ( p  = 0.01). However, no significant differences existed between mullet and tonguesole ( p  = 0.28) or between tonguesole and seabream ( p  = 0.06). ΣPBDE concentrations were negatively correlated with fish mass for all species; however, the correlations were statistically insignificant, suggesting a growth dilution effect.
